Study on Green Development Efficiency of Yangtze Economic Zone in China considering Resources and Environment
Authors: Wei Li , Junyi Yan , Jingkai Wu 
Published: December 2019

Abstract
This paper evaluates the green development efficiency of 11 provinces and cities in the Yangtze River Economic Zone considering resources and environment. Input factors include assets, human resources and resources. Output takes into account GDP and major pollutants (as unexpected output). This paper makes a static analysis of the economic development efficiency of the provinces and municipalities in 2015. Considering the resource and environment constraints, the overall economic development efficiency is constrained to a certain extent. The Malmquist index model is used to calculate the changes of economic efficiency in 2005-2015, which is decomposed into pure technical efficiency, scale efficiency and technological progress index. Considering the impact of resources and environment, the overall economic efficiency of 11 provinces in the Yangtze River Economic Zone showed an upward trend in 11 years, with an average MI index of 1.014. Technological efficiency (EC) is declining as a whole. Pure technical efficiency (PEC) is the main factor that causes the decline of technical efficiency, while technological progress (TC) is an important factor to promote the increase of development efficiency during the research period. The results of regional analysis show that the decline of technological efficiency (EC) in Sichuan, Yunnan, Hubei and Anhui provinces is mainly affected by pure technological efficiency (PEC). The decline of technological efficiency (EC) in Guizhou, Jiangxi and Jiangsu provinces is mainly affected by scale efficiency (SEC).

Authors: Yang Ping , Zhang Lei , Huang Yu , Ouyang Zebin 
Published: December 2019

Abstract
Nanomaterials are a new type of materials, which have been widely used in many fields. In the field of environmental governance and restoration, nanomaterials are highly concerned by scholars all over the world. Due to the small particle size, strong reducing ability, high surface activity and large specific surface area, nanomaterials have obvious advantages in the rehabilitation and treatment of contaminated soil and water. At the same time, due to the characteristics of small particle size, low solubility and weak degradation ability, nanomaterials will have adverse effects on the ecological environment. In this paper, through literature research, the application of nanomaterials in soil and water pollution remediation and treatment is summarized, and the repair mechanism and influencing factors are briefly described. At the same time, the impact of nanomaterials on ecological environment is also summarized. On this basis, this paper points out that further research on measures to reduce the impact of nanomaterials on ecological environment should be carried out in the aspects of soil and water pollution rehabilitation and treatment.
Study on Spatial and Temporal Changes of Ecological Vulnerability in Weinan Area Based on GIS
Authors: Hao Fu , Xinlei Liu , Xuxiang Li 
Published: December 2019

Abstract
With the development of urbanization, the ecological environment of the typical agro-development city-Weinan is disturbed to varying degrees, and it restricts the coordinated development of resources, population and environment in the region. This paper combines social, economic and climate data to propose an index system suitable for the evaluation of ecological vulnerability in Weinan. The analytic hierarchy process was used to quantitatively evaluate the ecological vulnerability of the Weinan region. The results showed that from 2000 to 2011, the urban ecological vulnerability index(EVI) was higher than that of the surrounding counties, which had a great relationship with the impact of urbanization on ecological vulnerability. The extremely fragile areas of ecological vulnerability in Weinan were mainly distributed in the urban areas of Linwei District and Hancheng. The main reason was that these cities had a fast development speed and a strong industrial base, which had a great impact on the ecological vulnerability.

Authors: Li Qiang , Dong Bochang , Xi Chenggang 
Published: December 2019

Abstract
The author selected three expressways in Guizhou as the research objects, and the runoff pollution characteristics were researched by sampling, measuring and analyzing runoff during the rainfall. According to the research data, the primary pollution factors in expressway runoff such as SS. COD and Petroleum had greater pollution intensity; the BOD5, NH3-N, TP and Pb had medium pollution intensity, which were defined as the secondary pollution factors; the range of BOD5/COD was 0.0351∼0.1025, which means a poor biodegradability for the expressway runoff. The expressway runoff showed different pollution characteristics and discharge rules, which were mainly affected by the rainfall and rainfall intensity. The first flush effect (FFE) was mainly medium and weak in the research area, and the degree of FFE was relatively weak under the light rain conditions, FFE didn’t occur in some rain events. This work is expected to pave the way for the pollution control of expressway runoff.

Published: December 2019

Abstract
The wastewaters produced in chemical production contain large numbers of persistent organic pollutants, posing potential adverse impacts to aquatic ecosystem and human health. In this work, the electrochemical degradation of organic pollutants in chemical wastewater belonging to Sunny wealth chemicals (Linyi, Shandong Province) was conducted using anodic oxidation process. Three commercially available anodes (Pt, boron-doped diamond (BDD) and Ti-Ru-Sn ternary oxide (Ti/RuO2-SnO2)) were chosen to investigate the effect of several primary operating parameters, such as electrolyte composition, electrolyte concentration and applied current density. Total organic carbon (TOC) was detected as reference parameters to assess the performance of anodic oxidation. The experimental results show that BDD anode exhibited excellent oxidation capacity for degradation of organics in chemical wastewater, achieving over 30% removal efficiency in all cases within 4 h. TOC removal efficiency of 52% was obtained with BDD anode in 4 h of reaction time at applied current density 30 mA cm-2, NaCl concentration 0.05 mol L-1; nevertheless, less than 45 % of removal was achieved with Pt and Ti/RuO2-SnO2 anode under the same conditions.

Published: December 2019

Abstract
In recent years, with the rapid development of cities, water resources are becoming increasingly scarce. Reasonable prediction of community water use is an important basis for regional water resources allocation, effective management of water resources and water conservation. The prediction model of BP neural network based on correlation analysis is established. Firstly, the influence factors of water consumption are analyzed by the correlation analysis theory, the influence size is sorted, and then the partial autocorrelation theory is used to analyze the daily water flow sequence, and the optimal delay time is determined, and then the input variables are determined. Then the BP neural network model is used to predict the water consumption of the community. Finally, the BP neural network model based on the correlation analysis is compared with the other models. The results show that the average error of forecasting model for residential community water consumption is 2.21% and the maximum relative error is 6.87%. Compared with the BP neural network model without correlation analysis and the least squares support vector machine model, the error is the smallest.

Published: December 2019

Abstract
Sediment heavy metal pollutant monitoring was carried out at 16 monitoring points of three rivers and one lake in Huai’an city. The contamination degree of heavy metals was evaluated by geoaccumulation index. The potential ecological risk of heavy metals was assessed. The results showed that Hg and Cu geoaccumulation index class exceeded moderately polluted level, especially Hg, and two monitoring points reached highly polluted level. Hg pollution is at a high/extremely high potential ecological risk. Most of the other single-factor heavy metal indexes are at a low ecological risk level. The comprehensive ecological risk index of 6 monitoring points showed a high potential ecological risk. The Hg in urban rivers sediment of Huai’an may come from the deposition of long-term domestic sewage discharge or domestic refuse dump.

Published: December 2019

Abstract
The reduction of fluvial sediment input has brought new features to the evolution of the Changjiang (Yangtze) Estuary. The response of river channels and shoals in the Changjiang Estuary are still unclear. A two-dimensional model of water and sediment transport in the Changjiang Estuary is established by using MIKE21. The sediment gradation and the flocculation of the fine sediment have been considered in the model. After calibration, the future evolution trend of the Changjiang Estuary was simulated based on the measured terrain in November 2016. The inflow of water and sediment at Jiangyin from 2008 to 2017 were taken as the upstream inlet conditions. The simulation results show that the pattern of river channel and shoals in the Changjiang Estuary will basically remain, and the main trend of bed evolution is erosion in deep channel and siltation of shoals.

Published: December 2019

Abstract
A calculation method of the risk index of oil spill pollution is presented, and main factors are considered in the method, such as the shoreline environmental sensitivity index ESI, the environmental sensitivity index SI, the statistical probability of the pollution, and the minimum time to be polluted. After 600 stochastic simulations of oil spill trajectory and fates model, the calculation of the pollution probability is carried out for the probability of the pollution to each segment of the shoreline and the minimum time to be polluted. The ESI and SI indexes, which indicate the shoreline environmental sensitivity, are determined by satellite image analysis, field investigation, data investigation and so on. The calculation method can be applied to the risk assessment of the oil spill accident with environmental conditions not determined, and provide the basis for the emergency preparedness and planning for the oil spill accident. The method was applied in Jiaozhou Bay, and the changes of the risk index along the shoreline was analyzed.

Authors: Zhao Jingjing , You Xueyi 
Published: December 2019

Abstract
To study the effect of Chinese dishes cooking activities on the health risk for domestic cook, numerical simulations are executed under different air flow rates for three oil-based Chinese dishes cooking activities. The concentration of formaldehyde in respiratory area during cooking process is obviously influenced by the cooking dishes. And the effect of air flow rate of range hood on the formaldehyde capture is not as significant as that of the cooking method. The predicated results show that the formaldehyde concentration is 4.5-5.5, 2.8-3.6 and 1.2-1.5 times of the prescribed limit when cooking the dishes of stir-fried mutton, pan-fried chicken with onion and deep-fried pork, respectively. The high air flow rate is recommended for improving formaldehyde capture efficiency (CE) of range hood. The potentially benefit effects induced by higher air flow rate is reliable in the cooking activity of stir-fry mutton. Using high air flow rate of 19m3/min can reduce the risk by 11.86% compared with using low air flow rate of 10m3/min. Low air flow rate is more suitable for cooking activities with low release rate of cooking oil fumes (COFs), in order to better protect the health of cooks.

Authors: Di Shengjie , Zhang Ying , Zhou Heng , Li Hongru , Huang Peng 
Published: December 2019

Abstract
Rainfall infiltration and canal seepage are the main causes of slope instability, the paper considered the factors such as soil type, soil-water characteristic curve and rainfall duration, and analysed the stability of unsaturated soil slope. The calculation results show that rainfall has a significant impact on the stability of the slope, as the matric suction in the unsaturated soil makes the slope safer. However, it reduced during rainfall, so the safety factor is greatly reduced when the continuous rainfall occurred. Moreover, when rainfall infiltration and canal seepage coupled, it is worse than just taking one factor into account, and the slope safety factor decreases from stable to unstable.
