MaxEnt model-ArcGIS-based evaluation of habitat suitability of Hedysari Radix
摘要
Abstract
AIM To evaluate the habitat suitability of Hedysari Radix based on MaxEnt model and ArcGIS.METHODS Using the MaxEnt model to screen the ecological factors affecting the distribution of Hedysari Radix,an evaluation model was thus established.ArcGIS software was used to evaluate the ecological suitability of Hedysari Radix to obtain the data about the highly suitable area,the moderate suitable area,the low suitable area and non-suitable area for its growth in China.RESULTS Hedysari Radix found its 1.29×106 km2 suitable area in China,among which the highly suitable area was 5×104 km2,mainly in Gansu Province,the moderately suitable area was 3.38×105 km2,and the low-suitable area was 9×105 km2,occupying 4.03%,26.20%and 69.77%of all,respectively.The main ecological factors affecting the distribution of Hedysari Radix were determined to be altitude,precipitation in the hottest quarter,solar radiation in September and December,seasonal temperature variation deviation and basic saturation of upper soil(0-30 cm).CONCLUSION With its result complying well with the literature records,this study provides theoretical basis for the introduction and cultivation of Hedysari Radix,and sustainable utilization of resources as well.关键词
