摘　　要：讨论了西双版纳地区热带雨林、人工橡胶林和无林农耕地集水区测流堰的选择与设计 ,并扼要介绍了集水区测流堰建设中应该注意的问题。用集水区测径流量是一种生态—水文试验的实用方法 ,它使生态系统与集水区界线一致 ,能相对准确测定集水区生态系统的水分输入和输出 。Site selection and design of V notch weirs in three different forested catchments (tropical seasonal rainforest,rubber plantation,and farmland) in Xishuangbanna are discussed.We also addressed some issues in the weir construction.It is a practical method to measure discharge by catchment weir.We can get relatively accurate data about input and output of water in the studied catchment. Furthermore, we can get the main factors about the water cycling in the studied ecosystem.
