内蒙古大青山主要林分类型水源涵养能力研究
THE WATER CONSERVATION OF THE MAJOR FOREST TYPES OF DAQING MOUNTAIN IN INNER MONGOLIA
摘要
Abstract
In this paper, the canopy interception, water holding capacity of litter and soil moisture level was observed in natural pine forest and the different ages of secondary birch, and the observation data were analyzed by SAS data processing software. The regression equation of natural rainfall and canopy interception was established. The result shows that soil water holding capacity is increasing from the Pinus tabulaeformis plantation andyoung-aged forest、middle -aged forest、matured forest of Betula platyphylla natural secondary forest, but there is a downward trend as soil depth increased. Soil water holding capacity of Betula platyphylla natural secondary forest is higher than that of Pinus tabulaeformis plantation.关键词
