摘　　要：以龙江县两种主要退耕还林地——樟子松嫁接山杏林地和红松林地为研究对象,以农田地作为对照,采用主成分分析法明确影响土壤状况的主要指标,对各样地进行综合评价,分析土壤理化性质,为该地区植被恢复及土壤修复提供科学依据.结果显示:各样地土壤容重、土壤pH随土层深度增加而增大,土壤有效蓄水量、土壤总孔隙度、土壤毛管孔隙度及土壤有机质含量呈减少趋势;农田地土壤有效蓄水量、土壤总孔隙度、土壤非毛管孔隙度、土壤pH、土壤有机质含量均低于山杏林地及红松林地;试验区域土壤理化性质综合评分由高到低为红松林地>山杏林地>农田地.农田地退耕对改善土壤状况具有一定促进作用.Taking two main types of forest land converted from farmland to forest land in Longjiang County sylvestris grafted with Pinus koraiensis forest and Armeniaca sibiric forest land as research objects,and farmland as control.Using principal component analysis to identify the main indicators that affect soil conditions,conducting a comprehensive evaluation of various land types,studying the soil physicochemical properties of returning farmland to forest land,and providing scientific basis for vegetation restoration and soil restoration in the region.The Results showed that the soil bulk density and soil pH of various areas increase with the increase of soil depth,while the effective water storage capacity,total soil porosity,soil capillary porosity,and soil organic matter content all show a decreasing trend;The effective water storage capacity,total soil porosity,non capillary porosity,soil pH and soil organic matter content of farmland are all lower than those of Armeniaca sibiric forest land and Pinus koraiensis forest land.The comprehensive evaluation scores of all the plots were as follows:farmland<Armeniaca sibirica forest land<Pinus koraiensis forest land.The above Results show that the conversion of farmland has a certain role in improving soil conditions.
