摘　　要：在GIS支持下,对三川流域3年的不同景观结构的水文生态效应进行了初步分析,研究表明不同景观要素的林冠截留量、枯枝落叶层厚度、土壤蓄水能力及土壤入渗率等存在差异,导致不同景观要素对水分的再分配和运移能力相差较大,三川流域3年不同的森林景观结构,致使该流域产生了不同的水文调节能力,1995年该流域的水文调节能力较强,而2004年的水文调节能力相对较弱,有林地的面积比例,尤其是阔叶林的面积比例在该流域3年的水文效应差异中起着重要作用。而在森林总面积相同的情况下,大斑块面积的森林更有利于水源涵养,在研究区进行小面积的造林,其水文调节功能并不理想,而大范围实施效果会更明显。With the support of GIS, this paper preliminaryly analyses hydrological ecological effects of landscape structures on three--riverbasin within three years, and the main conclusions are as follows： the canopy interception, litter thickness, soil water storage capacity and soil infiltration rate of different landscape elements have differences, which lead to quitely different water redistribution and migration capacity of landscape elements. There are different forest landscape structures of three-riverbasin during three years, which results show that the basin has a different hydrological adjust ability： in 1995, greater, and in 2004 weaker. The research results show that the proportion of woodland area, in particular the broad-- leaved forest, plays an important role at differentthydrological effects for the basin. In the same circumstances of total forest area, a large patch of forest area is more conducive to water conservation. Therefore, in the study area a small area for afforestation, the hydrological adjustment ability is not ideal, but the effect in large scale will be more apparent.
