不同森林-土壤类型在水源林生态系统中的作用

水源林是森林水文学的研究主体和实践区域，丘陵山区开发利用首先要解决水源林布局问题，使之达到生态平衡。文章探讨了不同的森林—土壤类型及其水源涵养能力，阐述了森林—土壤类型在森林生态系统中的基本核心功能，特别是林地土壤内的重力水库容在其中担负着重大的作用，并初步提出了营建和改造水源林的建议。

Effect of Different Forest-Soil Type in the Water Conserving Forest-Ecolsystem

Water conserving forest is the main study object and practice area of Forest-Hydrology. Prior to the development and utilization of the mountainous areas, the layout of water conserving forest should be dealt with so that the ecological balance could be achieved. This paper discusses different types of forest-soil and their water conservation capacity and demonstrates their basic and core functions in the forest ecosystem, especially the important roles the gravity water storage of the forest soil plays. Some suggestions on how to build and reconstruct water conserving forest are also made.
