通过对落叶松人工林实施强度（39.7%）、中度（32.8%）、弱度（21.6%）的抚育间伐试验,结果表明：抚育间伐能改变落叶松人工林的土壤理化性质,中度间伐区有机质、全N含量比对照提高107%和83%,有效N、速效P、速效K的含量均为间伐区大于对照区,土壤容重、持水量、孔隙度也为间伐区大于对照区;不同间伐区土层（5～20 cm）温度高于对照区1%～7%。光照强度以中度间伐为适度。降雨量为对照区〉弱度区〉中度区〉强度区。蒸发量为强度区〉中度区〉弱度区〉对照区。树冠截留量为对照区〉弱度区〉中度区〉强度区。

Larch plantation were conducted tending thinning experiments with heavy degree（39.7%）,moderate degree（32.8%）,weak degree（21.6%）.Result shows that： effects of thinning can change soil properties of larch plantation;degree of thinning area（32.8%） of organic matter,total N content are increased by 107% 83%;available N,available P available K content in thinning areas are more than that in the control area;soil bulk density,water holding capacity porosity in thinning area are more than that in the control area;temperatures of different thinning zones（5-20 cm） soil are 1%-7% higher than that of the control area;moderate thinning is optimal for light intensity.The sequence for rainfall is control area weak area moderate area heavy area.The sequence for evaporation is heavy area moderate area weak area control area.The sequence for canopy storage capacity is control area weak area moderate area heavy area.
