黄土丘陵区不同植被群落土壤水分研究
Study on the Soil Water of Different Vegetation Communities in the Loess Hilly-Gully Region
摘要
Abstract
In the semi-arid hilly and gully area with most severe natural conditions on the loess plateau, soil moisture is the major factor limiting the growth of plants, and environmental factor influencing on soil moisture is a comprehensive process, the effects of different geographical areas are very distincted, but to the difference in a specific area of scale, the controlling factors exist emphases. The soil moisture of vegetation communities in Zhifanggou watershed of loess hilly-gully region was analyzed. It could be known that the slope positions, aspect, altitude are the main controlling factors of soil moisture content in this area. And vegetation communities will also affect the change of soil water content, but cannot be the dominant factor.And it also can tell us that the age of forest is not the factor affecting the moisture content.关键词
