Potential Geographical Distribution of Quercus wutaishanica Forest and Its Dominant Factors
摘要
Abstract
In terms of the geographical distribution data of Quercus wutaishanica forest and the eight variables that potentially affect distribution of plants,including annual precipitation (P),annual range of monthly mean temperature (DTY),temperature of the coldest month (Tc) and temperature of the warmest month (Tw),growingday degrees above 5 ℃ (GDD5),moisture index (MI),annual amount of solar radiation (Radi) and elevation (Elev),four dominant factors,including P,Tc,GDD5 and Radi,influencing Q.wutaishanica forest distribution were selected with the MaxEnt Model.Thus,a relationship model between the geographical distribution of Q.wutaishanica forest and dominant variables was constructed.The results showed that this relationship model could effectively simulate the potential geographical distribution of Q.wutaishanica forest.The potential distribution regions include southern Northeast,central and south of North China,northwest of Central China,north of East China,eastern parts of Southwest and east of Northwest.The thresholds of the four dominant factors were 340 mm ≤ P ≤ 1060 mm,-17 ℃ ≤ Tc ≤ 4 ℃,800 ℃ · d-1 ≤ GDD5 ≤3 700 ℃·d-1,1.08×105W·m-2≤Radi≤1.41 ×105 W·m-2关键词
