- By the analysis on the status of severe increase of the contribution and harm from terrene non - point sources pollution in the merine environment of china , the need to research and develop the monitoring tracking technology of pollutans source was emphasized
摘要通过对我国近岸海域陆源性非点源污染污染贡献率及其危害性剧增现状的分析，强调了在我国开展污染源示踪检测技术研发的必要性。 - Water is always the main factor not only during the course of soil eroding but also during the process of non - point source pollution moving . so hydrological process of watershed is the central problem in the study of soil erosion and non - point source pollution with watershed in scale
无论在流域侵蚀产沙过程中，还是在非点源污染运移过程中，水都是主要因素，所以在以流域为尺度进行土壤侵蚀研究和非点源污染研究时，流域的水文过程是研究的主要问题。 - This study has designed and built non - point source pollution spatial database of the three - gorge reservoir area in chongqing based on geodatabase and case tools . the study has also workout the corresponding metadata standard and built non - point source pollution metadata . at last . this study assessed the non - point source critical area applying environmental model
本文基于geodatabase数据模型应用case工具设计、建立了重庆市三峡库区农业面源污染空间数据库，编制了相应的元数据标准并构建了重庆市三峡库区农业面源污染元数据，最后就三峡库区的农业面源污染应用环境模型进行了危险性评价。 - The outcomes show that the two methods can separate the basin pollution load from different sides , the two separation results are close to each other and can be provided as references for drafting pollution prevention policies and ; the proportion of the two pollution loads in the basin is more or less the same , point source is slightly heavier in a dry year and the proportion of non - point source pollution is greater in a wet year
结果表明，两种方法可以从不同的侧面分别对流域污染负荷进行分割，且两者分割结果相近，可以为流域污染防治政策的制定提供参考；流域内两类污染负荷所占比重大体相当，枯水年点源污染比重略高，而丰水年非点源污染比重较大。 - Hang - jia - hu water - net plain is the primary grain production base of zhejiang province . with a high population and intensive land utilization , agricultural non - point source pollution is extremely serious in this region . animal wastes , household cleaning products , farmland runoff and leakage mainly contribute to the anpsp
