摘要: 为了研究农业面源污染负荷空间分布及风险评估,综述了国内外近10年的最新研究进展,发现在农业面源污染空间分布及风险评估上的研究较多,其中污染的源因子及迁移因子空间分布研究进展颇多,而在综合风险评价上的研究还比较缺乏,对污染负荷的分布特征及其相关性的研究还存在不足,今后还需研究污染负荷分级区划与管理控制措施研究。本研究在介绍了农业非点源污染现状与面源污染来源基础上,对农业面源污染估算模型中分布式模型进行归纳对比,分别从区域性分布、降雨和土壤侵蚀、不同土地利用类型方面对农业面源污染空间分布特征进行分析;最后对中国不同区域农业面源污染风险评价结果进行了总结;并提出今后农业面源污染在空间分布和风险评价的研究重点。

Abstract: In order to study the agricultural non-point source pollution and risk assessment of spatial load, we summarized the latest research progress in recent 10 years at home and abroad, founding that there is more research in the agricultural non-point source pollution spatial distribution and risk assessment, including pollution source factor and migration factor on the spatial distribution of progress, but studies on the comprehensive risk assessment is a lack of research, distribution and correlation of the pollution load are still inadequate, so it is necessary to study on division and management measures to control pollution load classification.This research introduces the current status of agricultural non-point source pollution, analyzes the sources of agricultural non-point source pollution, summarized and compared agricultural non-point source pollution estimation model in distributed models. Agricultural non-point source pollution spatial distribution characteristics respectively from the regional distribution of rainfall ,soil erosion and different types of land use were analyzed ; finally, the result about evaluation on different regional agriculture non-point source pollution risk in China were summarized; and put forward the future research emphasis of agricultural non-point source pollution spatial distribution and risk assessment.
