对贵州喀斯特高原区的堆花小檗、小叶平枝栒子、矮生栒子3种灌木及无植被生长的土壤(0~20 cm)水分物理性质进行了研究。结果表明:(1)土壤容重大小依次为:无植被>矮生栒子>堆花小檗>小叶平枝栒子,且变化差异极显著;(2)土壤总孔隙度、非毛管孔隙度、毛管孔隙度的大小变化及相互间的变化差异显著性规律不一致;(3)土壤最大持水量,毛管持水量及最小(田间)持水量均表现出相同的规律,即:小叶平枝栒子>堆花小檗>矮生栒子>无植被,但相互间的变化差异显著性规律不一致;土壤蓄水量的大小顺序表现为:堆花小檗>小叶平枝栒子>矮生栒子>无植被,其中堆花小檗与小叶平枝栒子的变化差异不显著,堆花小檗、小叶平枝栒子与矮生栒子和无植被变化差异均极显著,矮生栒子与无植被变化差异显著。
對貴州喀斯特高原區的堆花小檗、小葉平枝栒子、矮生栒子3種灌木及無植被生長的土壤(0~20 cm)水分物理性質進行瞭研究。結果錶明:(1)土壤容重大小依次為:無植被>矮生栒子>堆花小檗>小葉平枝栒子,且變化差異極顯著;(2)土壤總孔隙度、非毛管孔隙度、毛管孔隙度的大小變化及相互間的變化差異顯著性規律不一緻;(3)土壤最大持水量,毛管持水量及最小(田間)持水量均錶現齣相同的規律,即:小葉平枝栒子>堆花小檗>矮生栒子>無植被,但相互間的變化差異顯著性規律不一緻;土壤蓄水量的大小順序錶現為:堆花小檗>小葉平枝栒子>矮生栒子>無植被,其中堆花小檗與小葉平枝栒子的變化差異不顯著,堆花小檗、小葉平枝栒子與矮生栒子和無植被變化差異均極顯著,矮生栒子與無植被變化差異顯著。

The soil’s (0 ~ 20cm) hydro-physical properties under Berberis aggregate, Cotoneaster horizontalis var. perpusillus, Cotoneaster dammerii forests and no bushes soil in Guizhou karst plateau area were investigated and studied. The results show as follows:(1) The soil bulk density values of the forest soil types ranked from high to low as follows: no bushes > C. dammerii > B. aggregata> C.horizontalis var. perpusillus, and the difference of soil bulk density values of each type varied extremely. (2) The regularity of size changes and difference changes inter the three porosity indexes of total porosity, non-capillary porosity and capillary porosity were not consistent. (3) The regularity of max moisture capacity, capillary moisture capacity and field moisture capacity in the four types soils showed the same rules, they ordered from big to small as: C. horizontalis var. perpusillus > B. aggregate > C. dammerii > no bushes, but the change differences of each types soils was not consistent; The water conservation capacity from high to low was B. aggregate>C. horizontalis var. perpusillus > C. dammerii > no bushes; Of them, the change difference between B. aggregata and C. horizontalis was not significant, the change differences among B. aggregata or C.horizontalis and C. dammerii or no bushes were extremely significant, and the change difference between C. dammerii and no bushes was significant.
