滇中高原区主要森林类型林地土壤蓄水功能

Water Retention Ability of Forest Land Soil of Main Forest Types in Central Yunnan Plateau

应用人工模拟降雨、径流场定位观测及林地土壤层持水能力等实测资料，从森林土壤入渗性能，地表径流和土壤侵蚀，林地土壤水分状况，土壤的持水能力和最大容水量等方面深入分析了不同森林类型林地土壤的水源涵养功能及其差异。

Based on the field measurement data of simulated rain trails,runoff position observation and water retention ability of forest land soil,the water conservation function of forest soil of different forest types were analyzed from the infiltration characteristics of forest soil,surface runoff,soil erosion,hydroregime of forest land soil,water retention ability and maximum waterreserving capacity of forest land,etc.
