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。 |
| 8. | For pollution prevention and remediation , countermeasures are proposed as follows , pollution source control , clean production , construction of more sewage treatment plants and related pipe structures , ecological agriculture enhancement and non - point pollution control , protection region construction in turbid areas
因此，对流域污染提出防治措施：从源头控制污染，推行清洁生产；增建污水处理厂及配套管网；发展生态农业、加快治理面源污染；建设湿地保护区等。 |
| 9. | The objective of this research is to test the rcc from ] st to 6th order streams of changjiang river watershed in southern mountain area of anhui province , to explore the function and structure of macroinvertebrate community succession rule of the river . the changjiang river water quality asse ssment is carry on by comparison of the community characters of the point - pollution or non - point pollution sites to the hypothesized rcc , the macroinvertebrate community structure indices and bi index were used in the assessment
本文对阊江河底栖动物群落结构和功能进行了系统研究，运用河流连续性理论对该河一至六级支流各取食功能团比例的演替规律及毛翅目成虫的群落结构进行了比较分析，并通过计算底栖动物群落结构指数和bi指数，对该河进行了水质评价。 |
| 10. | Physical - chemical data shows that slight - moderate point pollution exists in changjiang river . the inorganic pollution exists at the testing site of the 1st stream , and the predator ' s number at the testing site is obviously smaller than that of the reference site , while the number of shredder , collector and scraper each at the testing site is close to the number of those at reference site respectively
与参照点相比，一级支流检测点捕食者群落明显偏低，而撕食者、集食者及刮食者群落很接近，三级支流检测点集食者群落偏高，刮食者群落偏低，底栖动物种类单一化，而撕食者和捕食者群落比较接近。 |
