选择西双版纳热带地区３类不同植被覆盖小流域水文观测点，利用１９９５年７月～１０月的水文和降水观测资料，分析了月径流特征，并选取了大暴雨、连续降水后降大雨和连续无降水后降中雨等３种情况，对热带地区不同土地利用所引起的径流变化特征进行了初步分析，为西双版纳热带地区的水土保持、森林功效等研究奠定基础，并为有效地保护和合理地利用西双版纳地区的森林资源，促进当地经济的健康发展提供科学依据。
Three types of hydrological observation points in small watersheds covering different vegetation cover in the tropics of Xishuangbanna were selected. Based on the hydrological and precipitation observations from July to October 1995, the characteristics of monthly runoff were analyzed and the characteristics of heavy rainfall, heavy rainfall after heavy rainfall and continuous precipitation- Afterwards, this paper made a preliminary analysis on the characteristics of runoff changes caused by different land use in the tropical regions, and laid the foundation for the study of soil and water conservation, forest function and so on in the tropical areas of Xishuangbanna. In order to effectively protect and rationally utilize Provide the scientific basis for the forest resources in Xishuangbanna region and promote the healthy development of the local economy.
