摘要
本文利用自建的森林流域水文模型分析计算了龙门山地区的森林水文效应规律，并得出该区森林径流效应为正效应和森林洪峰效应为负效应的结论．在此基础上，评价了岷江上游地区森林水文效应对紫坪铺水库和都江堰灌区的影响，认为森林有助于提高工程与灌区的兴利效益与抗洪能力，河工措施与生物措施结合治理岷江势在必行．
The forest-hydroeogy effect law in longmen mount region is analyzed and computed by using the forest catchment hydrologic model developed by the authe forest-runoff effect is positive and the forest-peak effect is negative. The impacts of the ferest-hydrology effect in the upstream region at the Min river on Zipinpu reservoic and Dujiangyan irrigation region are assessed based on the model. The results indicale that the hi is conducive to raise the benefits and improve the flood -preventing ability of the reservoir and the irrigation region,and both hydraulic engineering measures and biologic measures are necessary to bring the Min river under control.
