| 摘 要： | 农田流域由于下垫面性质的复杂和农业管理活动对水文循环的影响,表现出了与自然流域不同的水文特征。通过对农业水文、农田水利方面的相关研究进行总结,从农田流域典型下垫面和农业管理活动2个角度,分析农田与自然流域水文响应差异,提出建立基于农田水文系统特征的分布式流域水文模型的若干考虑。

| Abstract: | Due to spatial variability of agricultural underlying surface and influence of agricultural management activity on hydrological process,agricultural hydrological system is obviously different from natural watershed hydrological system,which has more significantly spatial and temporal variability.Therefore,it has great sense to distributed-based model agriculture hydrological system,theoretically and practically.From the perspectives of both the typical characteristics of agricultural underlying surface and the hydrological effect of agricultural management activities,difference between farmland and natural watershed hydrological systems is analyzed.And the necessity of farmland watershed distributed hydrological modeling research is also discussed on details.On this basis,the challenges,focal points and the research direction of farmland watershed distributed hydrological modeling research are further illustrated and pointed out. |
