• After summarizing the experience of research and application about microbial sources tracking in anther countries , the project to research and development the monitoring tracking technology of the microbial source in shore of china was introduced
  在总结了国外治理非点源污染的经验微生物源示踪技术研究和应用现状的基础上，介绍了我国近岸海域微生物源示踪检测技术研发的设计思想。
• Non - point pollution source model is the important means of simulating non - point pollution , and soil erosion model is the foundation of non - point pollution model , and the affecting factors of soil erosion is the foundation of soil erosion model
  摘要非点源污染模型是进行非点源污染模拟研究的重要手段，而土壤侵蚀模型是非点源污染模型的基础，土壤侵蚀因子的研究是土壤侵蚀模型的重要基础。
• 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。
• The research results of the paper provides foundation to people rightly and rationally utilizing rainwater resource and controling pollution of not on the spot , and exploits a new effective way to the zone of lacking other recharging water source
  本论文的研究结果为人们正确合理的利用雨水资源，有效的控制城市非点源污染提供了依据，为缺乏其它补给水源的地区进行地下水人工补给开拓了一条行之有效的新途径。
• According to the present situation of the agricultural irrigation and water resources status , suggestions and possible solutions for water saving , proper distribution of water resources in hangzhou , and the reduction of water crisis as well as nonpoint source pollution were presented
  针对目前的农灌用水现状，对农灌节水、合理配置本地水资源、改善由农田灌溉引起的用水危机和农田径流引起的非点源污染提出了建议和措施。
• 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。
• Abstract : non - spot pollution source was analyzed qualitively and quantitatively on the basis of experiment data of pollution density variation during raining and flood process . the experiment result is in agreement with the observed reality . a calculation method for non - spot pollution source was presented
  文摘:利用雨洪过程中污染物浓度变化的试验资料，对非点源污染进行了定量和定性分析，指出非点源在雨洪过程中的作用特点与试验成果有很好的一致性，提出了一种粗略测算次雨洪非点源量值的方法。
• 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。
• To strengthen basins , non - point source pollution control , put the control into practice , build monitoring system online for pollution source , construct pollution treatment project , carry out research on oxygenation and direct - cleaning in lake or river , set up three gorges reservoir water pollution control laws and region regulations , deal with properly the ex - development between resource exploitation and environment prevention , and walk on the sustainable development road are important measures
  针对已发生和潜在的水环境污染问题，提出了加强流域非点源污染的管理、实施总量控制、建立污染源在线监测系统、立项建设污染治理工程、开展河湖水域接触氧化直接净化技术的科研和实践、制定《三峡库区水污染防治法》地方法规、正确处理资源开发与环境保护协调发展的关系、走可持续发展道路等多项防治对策与建议。
• 2 . the results showed that the contents of cach - extractable soil p , and soil test phosphorus ( olsen , bray , mehlich - 3 ) and algae - available p contents ( naoh - extractable soil p ) in the soils correlated significantly with the contents of ortho - p , particulate p and bioavailable p in runoff , respectively , which were feasible to be used as primary indices to evaluate of agriculture p impacting on surface water quality . the results also showed that the relationships between the phosphorus sorption of soil index ( psi ) , and the degree of soil saturation with phosphorus ( dpss ) and the contents of ortho - p , particulate p and bioavailable p in runoff reached significant level , respectively
  黄壤旱地土壤易解吸磷( cacl _ 2 - p ) 、土壤有效磷( olsen - p 、 bray - p 、 mehlich - 3 - p )或藻类可以利用的土壤磷( naoh - p )与地表径流中颗粒态磷、生物有效性磷和磷酸根态磷之间均存在显著的相关性，在一定的程度上可用cacl _ 2 - p 、 olsen - p作为指示黄壤旱地地表径流中磷潜在流失的预警指标，来判断旱地存在磷素非点源污染的可能性。
