Abstract

Abstract: Our research modeled the ecological niche of Picea crassifolia,Picea likiangensis,Sabina przewalskii,Populus cathayana,Pentaphylloides fruticose and Hippophae rhamnoides in Qinghai Province using MaxEnt by climate data,soil data,DEM and forest inventory data,and then determined the appropriate afforestation area according to forestry policy.All 6 species showed high accuracy during modeling(AUC=0.86~0.99).The results showed that the whole appropriate afforestation area of Qinghai reached 549.25hm² if we plant these 6 species in cropland (slope>25°) and bareland,which covered 0.01‰ of the province and is equivalent to 0.49‰ of the existing forest land and shrub land.The research also revealed that the appropriate afforestation is mainly distributed in Delingha,Dulan,Guinan,Gonghe,Nangqian,Banma and parts of Haidong and Xining.
