顺德地区不同森林改造区土壤水分—物理特性研究

The soil moisture physical characteristics of forest ecosystem at 7 sites in Shunde region were analyzed.The results show that the soil bulk density increases and the pore decreases with the increase of soil depth;the soil water holding characteristic of Jun'an town is superior to that of Jingping Hill and of Shuiniu Hill.Without the supply of rainfall and surface water and groundwater,the non capillary water will drain within 2 days,then the capillary water will be put into drainage slowly.As far as the availability of water is concerned,the soil water of the Shuiniu Hill will hamper the growth of plants,and of the others will not.
