| 摘 要： | 本文应用遥感技术资料调查大流域不同年代的下垫面组成及其结构变化,结合流域历年实测的水文资料和对不同森林植被—土壤类型降雨截留、枯落物贮存、土壤孔隙贮水及土壤渗透性的测定,评价不同森林植被—土壤系统的涵水能力,研究森林植被覆盖率变化对河川径流的影响研究表明,河川径流总量受大气候的影响.流域森林植被的变化对河川径流的构成和年内分配有决定性作用,大流域森林的采伐和恢复对河川径流的影响是一个渐变的过程.

| Abstract: | This study used remote sensing technology to investigate the composition and structure of valley in different periods combined with annual hydrologic date and determined information of rainfall interception , litter water storage , soil pore waterstorage and soil permeability , to evaluate the water storage ability of different forest plantation - soil system , to study the effects of forest plantation changes on Rivers Runoff . the results showed that the total volume of rivers runoff was affected by macro-climate , the changes of forest plantation had crucial effects on the composition and distribution in a year , the effect of cutting and recovering of forest plantation on rivers runoff was a gradual process. |
