摘要: 利用西双版纳热带季节雨林集水区1996—2006年日径流序列资料,计算出逐年基流指数值(BFI);以二水源假设理论为依据,用基流指数值对日径流资料做基流分割,计算出热带季节雨林集水区基流量。结果表明:西双版纳热带季节雨林集水区年基流指数值在0.24~0.45,均值为0.322,年间变化较小;月基流指数值在0.31~0.34,干季大于雨季;径流总量与降雨量年内变化趋势较为一致。本文结果将为热带森林生态水文功能研究和热带区域水资源的规划管理提供基础数据。

Abstract: Based on the 1996-2006 daily runoff data of tropicalseasonal rainforest catchments in Xishuangbanna, the annual base flow index (BFI) values of the catchments were calculated, and by using these BFI values to partition the daily runoff data according as the hypothesis of dual water source, the total base flow of these catchments was calculated with the help of BFI software. The annual BFI values of the catchments varied from 0.24 to 0.45, withan average of 0322 and changed less among years, and the monthly BFI values were 0.31-0.34, being higher in dry season than in wet season The variation pattern of the total base flow was similar with that of rainfall, and the former lagged behind the latter. The findings of this study could provide basic data for the research of tropical forest ecohydrological functioningand the management of water resources in tropical area.
