Authors: Lv Jie , Yuan Xiping , Gan Shu 
Published: September 2019

Abstract
Understanding past and current relationship between water-soil resources utilization and eco-environment is essential for predicting how these relationships may be affected by future human activities change. Combined with GIS technology and statistical analysis, based on the actual situation of water shortage, limited land resources and the prominent contradiction between the supply and demand of water-soil resources in the karst mountain area of southeast Yunnan province. This paper studies the coupling coordination relationship between the water-soil resources utilization and eco-environment in karst rocky region and evaluated the coupling coordination degree between the utilization of water-soil resources and the eco-environment by using the entropy weighting method and the system coupling theory. Results show that the model estimated the spatial and temporal variation between water-soil resources utilization and eco-environment parameters precisely. On this basis, the stress response mechanism of social and economic development and water-soil resources under the constraint of water-soil resources is further discussed by using impulse response function simulation, so as to provide theoretical and technical support for the sustainable development of regional water-soil resources.

Published: September 2019

Abstract
Sound speed profiles in the ocean have a significant impact on the acoustic propagation, thus affecting the sonar detection performance. Sound speed profiles have characteristics of positional and seasonal distribution. In order to guide the sonar detection, use WOA13 dataset, calculate the number of categories of sound speed profiles by hierarchical clustering method, classify sound speed profiles categories and typical sound speed profile structure of various categories in different seasons by fuzzy c-means clustering. It is concluded that there are 7 categories of sound speed profiles in Indian ocean: Antarctic Water category, Antarctic Transition Water category, Sub-Antarctic Transition Water category, Sub-Antarctic Water category, Sub-Tropical Water category, Tropical Divergence Zone category and North Indian Ocean Water category. The distribution area of these categories are generally zonal distribution. Sub-Tropical Water category, Tropical Divergence Zone category and North Indian Ocean Water category have significant seasonal variations. The seasonal variation of other categories are not significant.

Abstract
The southern Great Xing’an Range (SGXR) is one of the most important non-ferrous metal ore concentrating areas in China, and a large number of Pb-Zn and associated metal deposits have been found and mined in this area. The Early Cretaceous deposits of SGXR can be divided into three principal types according to their geological characteristics: skarn type deposits, porphyry type deposits and hydrothermal vein type deposits. In this contribution, we list some important Early Cretaceous deposits in the SGXR and summarize their geological characteristics. Research of stable isotope and fluid inclusion reveal that the sources and properties of ore-forming fluids varied between different types of mineral deposits, while the sources of ore-forming materials of different deposits are similar(characterized by deep-seated magmatic activities). We therefore conclude that the Early Cretaceous porphyry, skarn and hydrothermal vein type deposits in SGXR belong to a unified metallogenic series and developed a synthetical model for these deposits.

Abstract
The snapping shrimp is a member of the family Alpheidae, which is characterized by having asymmetrical claws. When it comes to danger or when it finds prey, the snapping shrimp will close its snapping claw rapidly, generating cavitation bubbles to stun or kill the prey instantly, accompanied by huge energy. This unique biological characteristic was studied since the 1950s, mainly on three aspects, the structure of snapping claws, cavitation jet properties of snapping shrimp and the mechanism of cavitation in snapping shrimp. The article summarizes the progress and results of the research from the above three aspects, and proposes the bionic technology is the research direction of cavitation by snapping shrimps in the future, which is based on research of the biological structure of the snapping claw.

Published: September 2019

Abstract
The purpose of this paper is to analyze the change trend of the virtual water trade for a 15-year period in Shandong Province, and to discuss how ecological environment is affected by numerous virtual water trade in a representative region. To carry out the analysis, the authors derived a water balance model from lateral economic balance formula in the input-output table. The model was combined with the economic data from Shandong Province’s input-output tables and environmental Kuznets curve for an analysis of the change trend of virtual water trade of different industries. Findings - The agriculture is the largest industry that consumes water among three industries, and it plays a conclusive role on whether Shandong Province export virtual water or import virtual water. The virtual water of the province was exported in 1997 and 2002 and imported in 2007 and 2012. This situation was in line with the change of the environmental Kuznets curve and such transformation can be considered a kind of repair to the ecological environment. When the net output volume of virtual water was zero, the total output value of agriculture was 257.86× 109 Yuan. About the representative region (Shouguang City), the annual irrigation water of vegetables is approximately 1.6× 108 m3, of which 84.5% water is exported to other areas in the form of vegetable trade. The virtual water quantity exported in the form of vegetable accounted for approximately 73% of the annual average groundwater resources. Shandong Province has insufficient water resources, and this study can provide a scientific basis for allocating water resources and repairing ecological environment.

Abstract
The continuous improvement of agricultural production efficiency is an important guarantee for the development of modern agriculture. Based on the input-output data of agricultural production in 9 cities of Guizhou from 2005 to 2014, the agricultural production efficiency was analyzed by the DEA-Malmquist index method. It shows that: Firstly, the total factor productivity (TFP) of agriculture in Guizhou showed a decline trend, the growth rate of total factor productivity was -1.9%, and the main reason of the decline is the reduction of pure technical efficiency and scale efficiency. Secondly, the leading factors of total factor productivity decline are different in different regions of Guizhou. Thirdly, the main reason for the fluctuation of Malmquist index with time is technological progress, and technological progress plays a important role in improving productivity. Scale operation, the enhancement of management level, and the enhancement of scientific and technological innovation can be used to enhance agricultural productivity.

Abstract
As for the tourism development of cultural community in ethnic area, the coexistence(symbiosis) of both the local tourism and local culture is not only connected with the relevant agents of them but also the relation of the relevant agents themselves. This is because harmonious coexistence(symbiosis) of the various agents is the elementary precondition of the ethnic cultural community tourism development. Symbiosis Theory was chosen as the theoretical perspective in this thesis, and Tu Nationality Hometown Park of Huzhu was selected as the study area. Then, symbiotic relationships and patterns of the various tourism agents were put into quantitative analysis. The findings displayed as the following: firstly, the four agents’ mutual characteristic symbiotic degree δM belongs to(ϵ) [0.719, 1.390], which illustrates that there exists the symbiotic relation between the every two agents of the four mutual agents and the symbiotic relations are totally positive symbiosis; secondly, the symbiotic coefficient 9m belongs to(ϵ) [0.34, 0.66], which approaches to 0.5 except the symbiotic coefficient of G-R(0.34). This illustrates that the mutual incidence of the other agents is basically the same except G-R; thirdly, the symbiotic relevancy of each agent approaches to one another, the symbiotic relevancy§m belongs to(e) [0.88, 1.08] concretely as R=E>G>T for the perspective of the tourism subject(tourists); lastly, the mutual behavioral patterns of the four agents of Tu Nationality Hometown Park of Huzhu belong to the patterns of positive reciprocal symbiosis(the positive symbiotic pattern of “residents-leading, enterprises-boosting” (REGT).

Published: September 2019

Abstract
The study of geodynamic processes observed in the Earth’s crust at densely populated and commercially developed areas in the east of Russia and China is of great importance for their sustainable development. The research results available show that not only natural, but also man-made geodynamic events associated with mining operations reflect the global geodynamic processes. Geodynamic events that occurred while mining in impact-hazardous areas allowed to identify some common features in the manifestation of natural and man-made geodynamic events in the eastern regions of Russia and China. Thus, both natural and disastrous technogenic geodynamic events (tectonic rock bursts, induced earthquakes, cracking on the earth’s surface) have positional connection with the linear zones of earth’s crust modern destruction (block boundaries and faults). Existing tectonic faults get re-activated during major geodynamic events, i.e. they get displaced in response to the mining operations. Areas hazardous for manifestation of geodynamic phenomena can be defined by geodynamic zoning method which can be used to draft the development programs for the eastern regions of Russia and China
The state of stress in the aftershock area of the March 11, 2011 Tohoku earthquake
Authors: Rebetsky Yu L , Yu Polets A 
Published: September 2019

Abstract
This paper presents the results of the stress inversion in the Earth’s crust in the Japanese seismic focal zone after the Tohoku earthquake of March 11, 2011. The stress tensor parameters are determined using the method of cataclastic analysis (MCA) of discontinuous displacements. The reconstruction of the stress state is based on earthquake focal mechanism data for magnitude range (Mw) 3.0–6.0. The calculations are performed at six depths. The 2011 Tohoku earthquake brought significant stress changes in the upper layers of the lithosphere of the continental slope (0-30 km). These changes have led to the emerging of extensive areas of horizontal extension here. The areas with changed geodynamic regime were not reduced over the past few years. The magnitude 9.0 Tohoku earthquake was a catastrophic mega earthquake and in this case the presence of an anomalous state of stress may take a long time.
Seismic regime of south Sakhalin before the Krillon earthquake 23.04.2017 (LURR and SDP models)
Authors: Zakupin A S 
Published: September 2019

Abstract
In the present work we show a fundamental possibility of a short-term prediction of strong shallow-focus earthquakes in the Southern Sakhalin (on the Krillon earthquake example, 23.04.2017, Mw=5.0). Retrospective modeling of earthquakes sequences from 2013 to 2017 based on the method of self-developing process (SDP) and the catalogue data of the local network has required. An auxiliary tool was used to improve the accuracy of the SDP estimates. It is a medium-term earthquake prediction method called LURR (load-unload response ratio). The previous results were improved using different sample data in the zones of active fault structures. This avoids ambiguity in the choice of the computational domain for SDP calculations. The zone of maximal anomalous levels of LURR coincides with that one we obtained a solution by the method of SDP. It happened 77 days before the earthquake. When compared with average estimates by the LURR method (two years), the prediction time was concluded to go down by 11 times.

Published: September 2019

Abstract
To conduct complex geophysical observations in the area of the Central Sakhalin Fault, an experimental geophysical test site was created, including a broadband molecular electronic type station and a new development of the Molecular Electronics Center - molecular electronic hydrophone. A module for placing a molecular-electronic seismometer at the test site has been developed and arranged. The noise level of the seismometer was analyzed and compared with the reference data. The results of hydroacoustic observations of weak earthquakes in the area of the Central-Sakhalin fault using a molecular-electron hydrophone are presented. The characteristics of the recorded acoustic emission signals from earthquakes perceived by the hydrophone station (frequency spectrum, arrival times of seismic waves) are investigated. The issues of operation and maintenance of molecular-electronic sensors with seismic signal data logger at various stages of seismological observations (setting up equipment, acquisition and storing data) were considered. The analysis of recording capabilities of seismic equipment was performed. Conclusions about the advantages and disadvantages of molecular-electronic sensors and their use on Sakhalin are made.

Authors: Yu Polets A 
Published: September 2019

Abstract
The present study presents the results of the stress tensor inversion in the Sakhalin-Island and adjacent territories. The method of cataclastic analysis of discontinuous displacements has been used to perform the stress reconstruction. The stress inversion has been performed on the basis of local focal mechanism solution catalog of earthquakes, NEID and Global CMT Project data. The calculations are carried out at three depths levels (0–6 km, 6–12 km and 12–18 km) for magnitude range (Mw) 3.0–7.0. The results of the stress reconstruction allowed us to obtain the new specific features of the tectonic stress field: orientation of the principal stress axes, stress ratio or Lode-Nadai coefficient and the types of stress (the geodynamic regimes). The tectonic stress field is less stable at depth between 6 and 12 km.

Abstract
According to the various scale GPS measurements, the process of collision between India and Eurasia is still ongoing and is reflected on Central Asia territory. The maximum velocity of shortening on northern component between India and Asia is ∼35 mm/year; the longitudinal (east-west) extension of the Tien Shan is ∼20 mm/year. The maximum deformations of shortening ∼15 mm/year along the north coordinate operate in a narrow fault zone between the Pamir and Tien Shan. Not on all Cenozoic (neotectonic) faults occur modern movements of the earth’s crust, these faults may have separate segments of active at different times. The general kinematic tendencies of modern movements correlate well enough with the general kinematic structure of neotectonic faults. In the fault zones at distances from the first hundreds meters to the first kilometers, intense elastic changes in the baseline lengths up to 4 cm (strains of 10–4) can occur within a week and up to 3-5 months. Such high-frequency elastic events have a different character of manifestations and are 2-4 orders of magnitude greater level than stable many years’ residual deformations.
