摘要
通过对湖北省郧县杨溪铺石灰岩母质发育的石碴地土壤的水分研究,结果表明:不同的土石比及不同的土地利用方式下土壤的持水性存在一定差异。砾石量少、土粒含量多的土壤持水性能强。在本试验的六种利用方式下,持水性从强到弱依次为:本试验的园地、草地、林地、小麦地、荒草地、荒地的土壤。而水分扩散率、饱和导水率从高到低依次为果园地、草地、小麦地、荒草地、林地、荒地的土壤。
The experiment is designed to subject to steely features of water in Yangxi town,Yun County ,Hubei province. We draw a conclusion that differences of water thread features engendered by different frontages of soils and rocks and utilizing methods if stumbling the amanda of gravel increasing the amble soil particle. The soil has a better capacity to substain water, This experiment carries six methods in order to get a better understanding and inference. Through this, we find that a sequence of the capacity of water and thermal is from strongest to weakest the line is soils of fruit garded, meadow, forest, wheat,the barren. If arrange sequence according to water diffusive coefficient from strongest to weakest,the line will be fruit garden ,meadow, wheat,forest, the barren.
