QIN Jia-hai1,JIN Zi-xue2,WANG Jin1,LIU Jin-rong3,XIE Xiao-rong3 (1.Department of Plant Science and Technology,River West Institute,Zhangye, Gansu 734000;2.River West Ecological Institute,Zhangye,Gansu 734000; 3.West Resource Environmental Chemical Key Laboratory,Zhangye,Gansu 734000)  
This paper with the bush forest,needle leaf forest and rich leaf forest of Qilian mountains 3 kinds of forest land is research material,discuss the different type of forest land as soil reason melts,the influence of nature and the selfcontrol function of source of water,show as a result: Soil porosity,granule structure and physicalness glue grain content is bush forest needle leaf forest rich leaf forest,soil unit weight and physicalness sand grain content are bush forest needle leaf forest rich leaf forest;Soil organic matter,whole N,N of quick result,P of quick result,K of quick result and CEC is bush forest needle leaf forest rich leaf forest,and CaCO_3,pH,completely salt content is bush forest needle leaf forest rich leaf forest;Soil water layer thickness,natural water content,saturation reservoir storage and woollen pipe reservoir storage,not woollen pipe reservoir storage,store water quantity is bush forest needle leaf forest rich leaf forest;Withered fall thing accumulation thickness,withered fall thing accumulation dry quality,hold water quantity,biggest hold water rate is bush forest needle leaf forest rich leaf forest.Bush forest plant kind is rich,closing degree big,withered fall thing accumulation quantity much,the self-control function of source of water is strong.
