凉水自然保护区主要森林生态系统的土壤湿度

A Preliminary Study of Soil Moisture in Major Forest Ecosystems of liang Shui Natural Conservation

采用实测法,分析了凉水自然保护区主要森林生态系统土壤湿度在不同深度、不同月份的动态变化及其差异。

Data of monthly variations of soil moisture at different hotizons in major ecosystems in Liangshui Natural Conservation were collected and analyzed.The soil moisture regime plays an important part n reasonable exploitation of land and water resources as well as protection of forest and ecological balance in the temperate and cold temperate zones.The soil moisture The results show that soil moisture increases with increasing precipitation and vegetation cover,but gradually decreases from topsoil down.
