荒漠化草原不同机械组成土壤水分运移规律研究
Study on Different Mechanical Composition of Soil Moisture Move Regularity in Desertification Grassland
摘要
Abstract
The soil moisture move law was studied by positioning methods of observation in different mechanical composition of desertification grassland. The results showed that water storage capacity and the preservation of the loose sand was less, it was higher in loam soil, and the annual soil water storage trend was basically the same due to the influence of rainfall; desertification grassland soil moisture active level existed in the layer of above depth of 110 cm, while in the layer of above the depth of 80 cm was most intense; the grassland vegetation recovery through the implementation of the fencing consumed a large amount of soil moisture for vegetation growth, resulting in the deficit of soil moisture and reduction of soil moisture reserves.关键词
