摘要
利用西双版纳人工橡胶群落试验集水区内测流堰１９９３年５月至１９９４年１２月的径流量与降水量资料，经分析结果表明：１）径流量年变化趋势与降水量相似，并且具有较好的相关性，雨季径流量大于干季径流量８～１０倍。径流量最小峰值出现在５月份，最大峰值出现在７月份；２）利用总径流量与降水量资料综合考虑分离出地下径流量与地表径流量；地表径流量较地下径流量偏小７０．３ｍｍ；地表径流与地下径流分别占总径流量的４５．３％和５４．７％。
The runoff and rainfall were measured in a catchment of manmade rubber community in Xishuangbanna from May,1993 to December,1994. The findings were as follows:(1)the annual variation of runoff was similar to that of rainfall, and there was a better relationship between them. Runoff amount in rain season is 810 times as large as that in dry season. Minimum runoff peak occurred in May, while maximum runoff peak occurred in July;(2)the underground and ground runoffs were divided based on the total runoff and rainfall data.The ground runoff is 70.3 mm less than underground runoff.The ground and underground runoffs were 45.3% and 54.7% of total runoff,respectively.
