摘要
漓江上游植被包括针叶林、阔叶林、竹林、灌丛和草丛等 5种类型。不同植被类型之间的水文特征与功能有较大差异 ,主要表现在对降水再分配、水量平衡和水文综合调节功能等的差别上。森林对河川径流的调节作用随森林水文功能的变化而变化。在评价各种植被类型水文功能的基础上 ,指出常绿阔叶林是亚热带水文功能最佳的植被类型。针对漓江面临的生态问题和漓江上游森林植被功能现状 。
The vegetation in upper reaches of Lijiang river could be divided into five elementary types, such as coniferous forest, broadleaf forest, mao bamboo forest, shrub wood and herb. The hydrological characteristics and functions of different vegetation types are variable, and it differs mainly in reallocation of precipitation, equilibrium of water and hydrological comprehensive adjusting ability. The forest adjusting function on rivers runoff alters as the forest hydrological function changing. On the basis of estimating the hydrological function of different vegetation types, it could be concluded that broadleaf forest is the best vegetation type of sub tropical hydrological function. The ecological rehabilitation strategies are suggested according to the problem of Lijiang river faced and forest vegetation function condition of Lijiang river upper reaches.
