摘　　要：以矸石山营造的火炬树林分为调查对象,观测其改良土壤理化性质作用,结果表明:林分土壤的物理性状有明显改善,土壤水分的渗透速率明显变小,较对照减少了18.86%,稳渗率较对照减少了57.73%;饱和含水量、自然含水量分别比对照增加了35.03%、37.28%,总孔隙度、毛管孔隙度分别比对照增加了23.07%、7.11%,非毛管孔隙和土壤容重分别比对照减小了5.53%、5.41%。土壤pH明显改善,平均值为7.62,较对照高出2.21;土壤有机质比对照高出36.15%;全N和速效N分别比对照高出50.00%和20.86%,速效K比对照高出64.50%,但全P和全K分别比对照低33.90%和25.88%。Rhus typhina Nutt. in waste hill had been taken as the objects, physicochemical properties of the soil characteristics had been observed , and the results showed that： forest soil physical properties were im- proved significantly, infiltration rate of soil water decreased significantly ,and was 18.86% lower than the con- trol , steady infiltration rate was 57.73% lower than those of control; saturated water content and natural water content were respectively increased by 35.03% and 37.28% than thc.~e of control, total porosity and capillary porosity were respectively increased 23.07% and 7.11%, non - capillary porosity and soil bulk density de- creased by 5.53% and 5.41%, respectively; soil pH was significantly improved, the mean value was 7.62, and it was 2.21 higher than the control; soil organic matter was 36.15 % higher than the control; total N and a- vailable N were 50. 00% and 20.86% ,higher,respectively available K was 64.50% higher than the control , total P and K were were 33.90% and 25.88% lower than those of control.
