摘要
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。
Runoff measurements were conducted at three catchments covered with different vegetation in the tropical region of Xishuangbanna, southern Yunnan in the period of July to October,1995. The impact of different vegetation on runoff characteristics was primarily analyzed in the three selected conditions of storm, heavy rain after continuous rainfall and moderate rain after continuous rainfall. The results was the basis for studying the soil and water conservation as well as the forest functions, efficiently proventing and rationaly using forest resources, promoting development of local economy.
