基于MaxEnt与ArcGIS的中国角茴香生态适宜性区划研究
摘要
Abstract
To predict and analyze the ecological suitability range of Hypecoum erectum by using maximum entropy model(MaxEnt)and geographic information system(ArcGIS)combined with relevant ecological factors.The 205 messages about the longitudes and latitudes of Hypecoum erectum in China were collected,and the potential suitable distribution area of Hypecoum erectum was analyzed by MaxEnt model and ArcGIS combined with 19 ecological factors.The main ecological factors affecting the potential distribution of Hypecoum erectum were precipitation in the coldest season,average temperature in the coldest season,precipitation in the warmest season,and the ratio of temperature difference between day and night to annual temperature difference.In the current climatic conditions,the highly suitable growth areas of Hypecoum erectum are mainly concentrated in Beijing,northern Hebei,Shanxi,Henan,Shaanxi,southern Inner Mongolia and other places,the area is about 77.4×104 km2;in the future climatic conditions,the suitable growth area will expand to the northeast and west.The predicted results of this study are consistent with the actual distribution area of Hypecoum erectum,which provides an important theoretical basis for the sustainable utilization and introduction and cultivation of Hypecoum erectum.关键词
