摘要
土壤侵蚀引起的农业非点源污染问题是20年来国际社会普遍关注的热点。从影响农业污染物运移的因素污染物运移定量评价模型,减少污染物运移的措施等方面概述了国外农业非点源污染的研究动态,提出了我国开展面源污染的研究的重点,包括侵蚀过程对非点源污染质运移和水质影响的机理,结合我国水蚀预报模型的研究,研发污染物运移的预报模型,制定全国统一的农业污染物危险性评价的指标体系。
Research work on agricultural non-point source pollution caused by soil erosion is a hot-point issue in recent 20 years. The author outlined the research development on overseas agricultural non-point source pollution, including the factors affecting agricultural non-point source pollutants, prediction models and measures to minimize agricultural non-point source pollution.Main research fields on developing agricultural non-point source pollution in China were also put forward, including research on processes and mechanisms of agricultural non-point source pollutants, developing prediction model and constituting indictors assessed potential risks of different agricultural non-point source pollutants.
