Abstract
The water level is an important indicator for lake operation management, and the variability of lake water level will have an important impact on the ecological suitability of aquatic vegetation. The ecological water level of lakes is the minimum water level for maintaining the structural and functional integrity and biodiversity of lake ecosystems. Therefore, it is very important to determine the ecological water level of lakes is for maintaining the harmony and stability of lake ecosystems. This paper analyzed the characteristics of water level, the lowest and suitable ecological water levels and the guarantee degree, by using the monthly water level data of Dianchi Lake from 1961 to 2016. The main conclusions are as follows: (1) The water level of Dianchi Lake mainly had a change period of about 15 years; (2) The abrupt change point of water level of Dianchi Lake occurred in 1994; (3) The lowest and suitable ecological water levels of Dianchi Lake and its actual water level had a typical unimodal distribution. The ecological water level in spring and winter was high, while that in summer and autumn was low. Thereinto, the lowest and suitable ecological water levels in May were lowest, 1885.86m and 1886.04m respectively, while those in November were highest, 1886.60m and 1886.78m respectively. (4) The guarantee degree of the lowest ecological water level of Dianchi Lake was as high as 93%∼95% within the year, while the guarantee degree of the suitable ecological water level could only reach 46%∼50%. The guarantee rate of the ecological water level during the low water level period was higher than that during the high water level period, and the guarantee degree of the interannual ecological water level varied greatly over the years. The lowest guarantee degree occurred in 1988 and 1989 with 0%, followed by the guarantee degrees of 50% and 8% in 1993, and they had reached 100% since 1994.

Abstract
Knowledge of vegetation dynamics is important for the sustainability of natural resources and understanding the changes in ecosystems and its impact to earth’s environment. We have carried out analysis of GIMMS (Global inventory modelling and mapping studies) NDVI3g (third generation normalized difference vegetation data for the period 1982-2015. Based on the Linear Regression (LR) analysis, the Mann-Kendall (MK) test with Sen’s slope estimator and Kriging interpolation method, we have investigated the spatiotemporal variations of vegetation NDVI in the Yangtze River Basin (YRB). The results show pronounced increase in the annual mean NDVI at the rate of 0.01/10yr during 1982-2015, with significant turning point (TP) around 1994. The spatial distribution of the annual mean NDVI reasonably increased in the northern, eastern and south-western YRB, while decreased in the Yangtze River Delta (YRD) and parts of the southern YRB during 1982-2015. Pronounced change in NDVI trend is found in different seasons, for example, the increasing trend during spring (0.02/10yr) and in autumn (0.02/10yr) was higher compared to winter (0.006/10yr) and summer (0.002/10yr) seasons.

Abstract
This paper shows the sea level variations (SL) over zhejiang province, china. Using Sea surface height data which obtained from the European Centre for Medium-Range Weather Forecasting (ECMWF) and Sea surface temperature (SST) data to validate the correlation of them. Monthly, seasonal, annual and decadal variations of SL over ZJ and its subareas are presented and discussed in this research. SL shows an increasing trend on the whole. However, there is a decreasing trend between the years of 1975 and 1987, then SL shows increase. Over the ZJ province, the rising rate of SL is 0.343cm/a from the year of 1958 to 1975 and the rising rate of SL is 0.238cm/a after the year of 1987. The overall rising rate of SL in the ZJ province is 0.172cm/a from the year of 1958 to 2015, then we can also find that the dropping rate is 0.264cm/a from the year of 1975 to 1987. The Maximum SL height of ZJ province is in 2012. Further SL variations have been done over the ZJ province which includes Hangzhou Bay (HZB), Ningbo (NB), Zhoushan (ZS), Shengsi (SS) and Wenzhou (WZ) areas. We have checked the steric effect with SST on SL. It was found that there was a positive correlation (CC = 0.77) between SL and sea surface temperature (SST), and the same correlation was observed in other areas of Zhejiang Province.

Published: April 2020

Abstract
When ship sails on the water surface, it will form a wake containing a large number of bubbles for different scales. The existence of bubbles will cause the attenuation of sound waves. In this paper, bubbles with different sizes are generated in the pool by using ceramic tube array. An experimental study on the acoustic attenuation characteristics of sound waves in bubbles was carried out for still water, small bubbles, medium-sized bubbles and large bubbles. Through experimental research, it is found that the existence of bubbles makes the acoustic signal decay obviously. At different frequencies, bubbles decay more than 10dB relative to still water. Large bubbles have the strongest attenuation effect on acoustic signals, averaging over 20dB. The medium and small bubbles are similar to the attenuation of the acoustic signal. The acoustic signal intensity in static water and different scale bubbles is basically the same as the frequency.

Published: April 2020

Abstract
The use of vehicle image detection to detect traffic information along roads is a key technology for high-precision navigation map updating. At present, China’s roads are developing rapidly. Traffic signs along the roads are constantly updated as the roads change. An accurate and efficient method for detecting traffic signs along the roads is yet to be proposed. Aiming at this problem, this paper proposes a road traffic signage change detection method based on Grayscale Adaptive SVM (Support Vector Machine). First extract the traffic signs in the two-stage image, rotate and interpolate the operation, automatically rotate the guide card to the horizontal, and zoom to the uniform size, grayscale the image pair and extract the changed part using the SVM model, and finally use the morphological operator. Process images to remove the effects of “salt and pepper” noise. Through experimental verification, this method can detect changing areas accurately and efficiently, eliminate the influence of parallax, and have a higher degree of automation.

Published: April 2020

Abstract
Based on the analysis of driving factors of urban drought, this paper adopts different methods of water balance and drought identification for different water supply sources, such as local water storage and transit runoff. By calculating the city water shortage rate and frequency under different water supply conditions and combining with the benefit analysis model of water supply for each water using sectors, the relationship curve between water loss and water shortage rate for each major industry in cities and towns is established. Based on the dynamic optimal distribution of water shortage for each industry and the forecast results of precipitation and runoff, the dynamic loss and risk assessment method for urban drought with different water supply sources is put forward. Taking Qidong County and the towns of Hengyang City along the Xiangjiang River as examples, the model method is validated. The results show that there is a power function relationship between the urban drought loss and the water shortage during the drought period, the models may provide theoretical reference for optimizing urban water allocation management and making urban drought resistance plan.

Published: April 2020

Abstract
Shipping is one of the main modes of transportation, and the safety of ship operation is very important. The navigation conditions of the inland river are complex. The width of the river, the density of the ships and the height of the bridge all affect the navigation of the ships to a certain extent. Based on this, this paper proposes a decision-making optimization method for collision avoidance of inland ships based on intelligent calculation. By analyzing the process of ship collision, the genetic algorithm in intelligent calculation is used to avoid collision. The simulation results show that the best collision avoidance effect is achieved in the collision avoidance of the two ships and the collision avoidance of the ship and the bridge, which reduces the risk to the lowest level.
A Preliminary Study on Promoting the Use of Solar Energy Roof in Residential Building in Jinan
Authors: li Yanwei 
Published: April 2020

Abstract
The excessive development and utilization of traditional energy makes the energy fuel (oil, coal, etc.) on the earth tend to be exhausted. At the same time, the pollutants discharged in the process of use have caused serious harm to our living environment, resulting in increasingly acute environmental problems such as climate warming and air pollution. Solar energy is inexhaustible clean energy. At present, the use of solar energy in Jinan residential buildings mainly focuses on the installation of solar water heating system in the south facade of the building, while the use of roof of residential buildings is very little. There are two ways to use solar energy on the roof of residential buildings: photovoltaic power generation and light heat conversion. Through these two ways, solar energy is converted into electric energy and thermal energy. There are many favorable factors to promote the use of solar roof in Jinan residential building. First of all, Jinan has a long sunshine time. Secondly, the usable area of Jinan residential building roof is large. In addition, the solar energy roof of Jinan residential building has a double energy-saving effect. Finally, the solar energy roof has little adverse effect on the appearance of the residential building in Jinan.

Abstract
Value-for-money evaluation can provide decision-making basis for the selection of public project implementation mode. As far as the current situation is concerned, there is a great controversy in the quantitative evaluation of value for money. This paper attempts to explore the option value ignored in the evaluation process of PPP projects by using the concept of triangular fuzzy number in real option B-S model and combining with the traditional quantitative evaluation model. Taking a tourism creative park project as an example, the uncertainty value range is calculated without completely deviating from the existing evaluation system, so as to provide a more comprehensive perspective for the quantitative evaluation of value for money.

Abstract
Traditional villages are a typical representative of the regional human settlements in Xinjiang. In order to clearly understand the general public’s basic understanding of the landscape environment of Nanjiang villages. The author strives to collect individual cognition into group cognition, and conduct data statistics in different categories to form a scientific basis. Therefore, the article takes the traditional villages of oasis in the Tarim Basin (commonly referred to as the southern Xinjiang) as the research base, and uses field visits, questionnaire surveys, and photo shoots. It mainly uses big data survey and analysis software and field surveying and mapping as specific implementation methods. The three independent variables include who was interviewed, the province where the mobile phone IP belongs, and the occupation. The three dependent variables include the recognition of the status quo of the traditional village landscape environment, whether the village residential planning and design should have regional cultural characteristics, and its effect on rural rejuvenation and long-term stability. The two types of variables are comprehensively analyzed by combining them individually and crosswise. The comprehensive results show that the interviewees in this study have wide coverage, reasonable composition and accurate data. From the perspective of data quantification, it is enough to prove that the achievements of rural planning and construction in Xinjiang in China are obvious to all and won the hearts of the people. At the same time, it provides important intellectual support for the planning and improvement of the landscape environment of traditional villages in southern Xinjiang.
