【摘要】 国外森林和水分的关系的科学研究始于20世纪初,森林与径流关系的研究方法大致有大范围的计量分析研究、一个林区或林场的计量调查、小范围的定位观测试验3大类。森林对径流影响的研究主要有森林对年径流的影响、森林对洪水径流的影响、森林对枯水径流影响等几个方面。今后应加强合作研究,特别是利用网络研究对比不同集水区之间的结果来探讨森林对径流的影响,同时重视新技术和新方法的应用。更多还原

【Abstract】 The reserch in effect of forests on river run-off was began in 1900 s,but its was began in 1949 s in China.There are three methods including Metrological analyse research,catchment research and little scale location research.The relation of the forest and hydrology included the influence of forests on run-off total value of years,flood run-off and exhausted run-off.A developing trend to study is the combination of data from a number of catchments that have different characteristics and the application of new measuring technical and approaches.更多还原
