摘要: 以中国生态系统研究网络长期定位观测的西双版纳热带季节雨林、鼎湖山亚热带常绿阔叶林、哀牢山中山湿性常绿阔叶林和长白山阔叶红松林为基础,分析比较4种森林类型土壤水文功能的差异。研究结果表明:土壤容重随土层深度增加而增大,土壤孔隙度、有效含水范围、饱和含水量和月均含水量随土层深度增加而降低;鼎湖山地表径流量及其占总降雨量的比例最大,哀牢山蒸散量及其占总降雨量的比例最大;4种森林类型0~50cm厚度土壤最大吸水能力为哀牢山>鼎湖山>长白山>西双版纳,蓄水量则为鼎湖山>长白山>哀牢山>西双版纳。

Abstract: Based on the location observation data of Chinese ecosystem research network about four typical zonal vegetations, this paper analyzed the difference of hydrological functions in different climatic zones. The results showed that the soil bulk density increased with soil depth, but soil porosity, soil effective moisture, saturation moisture content and water content per month are opposite. The runoff of Dinghu Mountain was the highest among the four forests and consumed the largest portion of precipitation. The evapotranspiration of Ailao Mountain was the highest and consumed the largest portion of precipitation; the soil water absorption capacity of Ailao Mountain was the largest and followed by Dinghu Mountains,Changbai Mountains and Xishuangbanna, while the soil water storage ability of Dinghu Mountain was the highest, and followed by Changbai Mountains,Ailao Mountains and Xishuangbanna.

Key words: zonal vegetation, soil, hydrological function
