土地利用/覆被变化(LUCC)充分体现了人与自然之间相互作用的关系,特别是LUCC对径流量的影响备受全球的关注。本文总结了LUCC对径流量影响的主要研究方法(对比试验流域法、统计分析法、模型模拟法、分离评判法)和前人的研究工作,分析了备受关注的森林和城镇化对径流量的影响、气候条件和不同土地利用/覆被类型对径流量和洪水过程的影响评价,以及量化气候条件和土地利用/覆被对净流量影响贡献率等几个方向研究进展,并讨论了在研究过程中存在的问题和未来可能的研究趋势。

[Abstract]
Land use / cover change (LUCC) fully reflects the interaction between human and nature, and especially the impacts of LUCC on runoff have received global attention. In this paper, the main research methods (comparative watershed method, statistical analysis method, model simulation method, and separation judgment method) and previous research progress of the impacts of LUCC on runoff were summarized, the impacts of variation of forest and urbanization on runoff were analyzed, the impacts of climate conditions and different land use/cover types on runoff and flood process were evaluated, the research progresses of quantitative assessment of the contribution rate of the above impacts were introduced, and the existing problems and future research trend of the impacts of LUCC on runoff were discussed.
