According to the detailed analyses of the AGNP distribution characteristics and existing problems in Lake Nansi Basin, it showed that land utilization rate is high, livestock and poultry breeding and aquaculture breeding are excessive and sewage collection system has not been established yet and so on. Based on the above-mentioned problems, this paper points out some useful countermeasures such as optimizing the land utilization structure, adjusting the agricultural planting structure, live stock aquaculture integrated system, strengthening the harmless disposal piling up of solid waste, comprehensive utilization of crop straw, rural domestic waste ecological treatment.

Water environment safety is increasingly gaining public attention in recent years. To assess the degree of water environment safety, an evaluation index system associated with system dynamics (SD) was built. Water environment safety degree (WESD) is affected by a comprehensive system. As the effective tool for complex system simulation, SD approach was used to simulate the relationship between water environment and social activity. Taking Zhejiang Province as an example, the study was on the assessment of WESD from 2003 to 2010 and prediction from 2011 to 2015 in high, normal, low development scenarios. Results suggest that index parameters should be revised according to the development of society in order to get more accurate and reliable assessment results, and that the approach is reasonable to mimic the actual situation and to predict the future water environment safety degree.

This paper analyses the relationship between integration which is one of variables of space syntax and standard land price based on the output of Axwomen which is one free software integrated by space syntax and GIS. Taking Huangshi as an example, this paper makes the correlation analysis between the standard land price and integration. The result shows that there is significant correlation between them according to which the standard land price can be verified and optimized. When forecasting the future land price based on these result, the other elements should also be considered.

Analysis of the data in the last six years by applying the gray theory model GM (1,1) revealed the amount of the water resources in Northwest China. On inspection, the relative error rate of the fore-cast results are all less than 0.1. This paper lists the analysis process of gray model, as well as the original data and projections fitting curves equation, which indicate obviously that the model can be well used for the prediction of the amount of water resources.

The sewage samples in the combined sewer system of the typical mountainous city were collected and analyzed during dry and wet weather. Results showed that grit from influent had obvious change curve during 24 hours in dry-weather. The average concentration of grit from influent was about 183.9 mg.L-1. The loads of grit were higher than value designed in the Fuling Wastewater Treatment Plant (WWTP). Grit variation curve was associated with the sewer flow discharge in collection system. In wet-weather, the peak concentration of grit from initial rainfall was at least eight times more than that in dry-weather. The average concentration of grit during the wet weather of sampling was 405.5mg.L-1 in combined sewer system. In the sanitary sewer in the commercial zones, the average concentration of grit was 426.2mg.L-1. Because of the dilution effect of rain in a rain pipe, the grit concentration was only 199.1mg.L-1. Up to 50% of the grit entering the Fuling WWTP may be 200 microns or smaller. It is difficult for the existing grit removal systems to efficiently remove the grit 200 microns or less. For removal of smaller grit, a grit removal device should be designed for removal of grit and sediment particles near 100 microns in particle size. Regardless of dry weather and wet weather, the WWTP of the mountainous city had to pay more attention to the grit removal system.

SWAT model was selected to investigate the effects of land-use change on sediment yield in the upper Huaihe river. On the basis of the simulated sediment concentration, the effects of land-use change on soil erosion modulus and rainfall-sediment yield relationship were analyzed. The results showed that under the similar rainfall, soil condition and slope, the sediment yields ascended with woodland, paddy field and farmland. The outputs could provide references for soil and water conservation and river health protection in the upper stream of Huaihe River.

To meet the demand of crops irrigation water, the optimal planning model of the field water saving irrigation, in which minimum incremental annual cost of field water saving irrigation engineering is the objective function, has been established based on types of water resource, agricultural utilizable water yield, crop planting structure, status of water saving irrigation and feasibility of each water saving irrigation technology. To use the model, the Xinjiang Hetian region optimal plan of water saving irrigation that includes optimal development scale of water saving irrigation for each crop in the region has been put forward in 2020. The model provides a scientific basis for reasonable planning of water saving irrigation and optimal allocation of water and land resources in region.

Based on MODIS data and Mann-Kendall test, our study put forward a method of combining EVI (enhanced vegetation index) and TCWI (Tasseled Cap wetness index) to monitor the ecological health of wetlands and adjacent uplands. In terms of the experimental district in Zoige Basin, a series of the ecological restoration projects implemented in recent years has not yet measurably improved the ecological health in wetlands and adjacent uplands, and the unfavorable affection from overgrazing is still obvious. The above conclusion is identical with several latest research results from other scholars based on both the post-classification change monitoring and landscape structure indices. This proves that our method is reliable; it will have great potential for popularization.
本研究基于MODIS数据和Mann-Kendall检验，提出了一种结合EVI (enhanced vegetation index)和TCWI (Tasseled Cap wet index)的湿地及邻近高地生态健康监测方法。若尔盖盆地试验区近年来实施的一系列生态修复工程，对湿地及邻近高岭地的生态健康改善效果尚不明显，过度放牧的不利影响依然明显。以上结论与其他学者基于分类后变化监测和景观结构指标的最新研究结果一致。这证明我们的方法是可靠的;它具有很大的推广潜力。

In this study, the wastewater containing 10mg/L lead was treated by five different kinds of mixed substrates of constructed wetlands. The results indicated: (1) For total Pb, substrates 1, 4 and 5 showed significantly higher capacity than other kinds; (2) In five fractions, bound to Fe-Mn oxides and residual Pb were treated with higher efficiency than other fractions; (3) There were significant changes between the content of total Pb and that of five fractions in substrate 5; (4) Bound to carbonates and residual Pb showed an upward trend, but exchangeable and bound to OM Pb showed upward trend firstly, and then showed downward trend. The bound to Fe-Mn oxdies fraction Pb showed downward trend.
