达乌里秦艽潜在适生分布区研究
Study of Potential Distribution Regions of Gentiana dahurica
摘要
Abstract
Objective:To study effect of ecological factors on distribution of Gentiana dahurica and predict the potential suitable distribution regions of G.dahurica in China.Methods:By using 154 distribution recordings in China and 28 ecological factors and combined with ArcGIS,the effect of the ecological factors on the suitable distribution regions of G.dahurica and the potential suitable distribution regions in China and each province were studied by MaxEnt.Results:The main factors effect of the suitable growth of G.dahurica were altitude,the highest temperature and the precipitation in January.10 provinces in China existed higher suitable distribution areas for G.dahurica.The suitable distribution areas were 577 517.4 km2,accounting for 6.02% of the total area of the country.Gansu province had the largest areas for the suitable growth of G.dahurica,and the second was Qinghai.Conclusion:The results could guide for resources native protection and wild nurture of G.dahurica.Meanwhile,it could provide scientific basis for selecting cultivation fields and suitable production area of G.dahurica.关键词
