摘要
随着全球变化研究的深入,土地利用/覆被变化(LUCC)与水文过程的相互作用成为全球生态与环境研究的热点和前沿问题。在阐述土地利用/覆被变化对水文过程影响特性的基础上,从LUCC对径流影响的研究成果、研究方法,以及模拟尺度等方面概述了LUCC对水文过程影响的研究进展。综合分析表明,由于区域气候和地理的差异性,以及研究尺度和方法的不同,特定流域上LUCC对水文过程影响的结论难以取得一致。需要考虑多方面因素,正确评价LUCC对水文过程的影响,加强生态环境效应研究,为流域土地利用规划和水资源的合理配置提供科学依据。
With the in-depth study on global change,the interaction research between land use/cover change and hydrological processes has been the focus of attention and the international frontier of global environmental and ecological research.The influencing characteristics of land use/cover change on hydrological processes was expounded.On the basis,the researches about hydrological response to LUCC were reviewed,including the progress,study methods,and simulation scale.Some conclusions were drawn as follows.Due to different region climatic conditions,geographic locations,study scale and methods,hydrological effect of LUCC in specific basin showed as certain difference.Therefore,various factors need to be considered comprehensively,and the impacts of watershed land use/cover change on hydrological processes should be correctly evaluated.Besides,the eco-environment effect should be strengthened so as to provide scientific evidences for land use planning and rational allocation of water resources.
