文摘The soil moisturephysical 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 waterholding 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 noncapillary 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.
