基于最大熵模型预测莼菜的分布格局与主导环境因子
Prediction of Distribution Pattern and Dominant Environmental Factors of Brasenia schreberi Based on Maximum Entropy Model
摘要
Abstract
In order to investigate the distribution pattern and dominant environmental factors of Brasenia schreberi,this study calculated and analyzed the existing distribution data of Brasenia schreberi based on 19 bioclimatic factors and 3 topographic environmental factors by using the maximum entropy model and Arc-GIS software.The results showed that the area under curve of the model was 0.930,indicating that the prediction results of this model were highly accurate;the dominant environmental factors affecting the dis-tribution of Brasenia schreberi were the minimum temperature of the coldest month(bio6),the precipitati-on in the coldest quarter(bio19),the seasonal variation of precipitation(bio15),and the slope.During the current period,Brasenia schreberi was mainly distributed in Hubei Province,Zhejiang Province,Chongqing Municipality,Sichuan Province,etc.Under the future climate conditions,the amount of Brase-nia schreberi in the suitable areas under both the SSPs126 pathway and the SSPs585 pathway increased significantly,with a higher percentage of increase under the SSPs585 pathway.The results of this study provide an important scientific basis for the selection of suitable areas for Brasenia schreberi planting and rational cultivation.关键词
