农业面源污染模型研究进展

Research progress of agricultural non-point source pollution models

介绍了USLE、CREAMS、EPIC、ANSWERS、AGNPS、AnnAGNPS、SWRRB、SWAT等常用的农业面源污染模型的研究历程,讨论了模型的基本组成、特点和现有问题。针对农业面源污染模型在数据获取、模拟结果和模型引进本土化等问题,提出了新的研究思路。对发展趋势的分析可以发现:农业面源污染模型将更多地作为大型流域集成管理模型的第一部分进行开发,并且向环境评估和管理等方面发展;新兴技术可促进模型优化,“3S”技术将成为农业面源污染模型研究的热点。

The research process of common agricultural non-point source pollution models such as USLE,CREAMS,EPIC,ANSWERS,AGNPS,AnnAGNPS,SWRRB and SWAT were introduced,and their basic composition,characteristics and existing problems were discussed as well.In view of the problems regarding data acquisition,simulation results and localization of imported models,several new research ideas were proposed.The analysis of future research show that the agricultural non-point source pollution models will be developed more as the first part of the integrated management model of large watersheds focusing on environmental assessment and management.New techniques helps optimize models.In particularly,"3S"technology will become a research hotspot of agricultural non-point source pollution models.
