Climate Suitability and Potential Distribution of Sophora japonica L.Based on ArcGIS and MaxEnt Model
Based on the collected distribution data of wild Sophora japonica L.,combined with the envi-ronmental factor,the ecological suitability and potential distribution of Sophora japonica L.was studied by using the MaxEnt model and ArcGIS software.The results showed that the key climate factors affecting the distribution of Sophora japonica L.were the lowest temperature in the coldest month(Bio6),annual precipitation(Bio12),and the lowest temperature in April(Tmin4);the ecological niche parameters for Sophora japonica L.were that the lowest temperature in the coldest month was-11.1-12.7℃,the aver-age annual precipitation was 480.0-2455.0 mm,and the lowest temperature in April was 4.3-21.1℃.Sophora japonica L.in China was mainly concentrated throughout east and central China,as well as in parts of northeast,north,northwest,southwest and south China.The predicted results were basically consistent with the actual distribution of Sophora japonica L.,which could provide a reference basis for the resources protection,germplasm collections and reasonable development and utilization of wild Sopho-ra japonica L..
