Prediction of Ecological Suitable Area and Analysis of Dominant Environmental Factors of Cordia dichotoma
摘要
Abstract
Objective:To predict the suitable areas of Cordia dichotoma in China by using the existing distribution data,and ana-lyze the dominant environmental factors affecting its growth,so as to provide reference for the protection of wild Cordia dichotoma germ-plasm resources and the location of introduction and cultivation.Methods:Based on the data of 130 wild distribution points of Cordia di-chotoma obtained from field investigation,literature database and specimen database,8 limiting factors affecting Cordia dichotoma distri-bution were selected from 19 bioclimatic parameters by Pearson.The MaxEnt model was used to predict the potential distribution area of Cordia dichotoma in China.Results:The average temperature in the driest quarter,the lowest temperature in the coldest month,the rain-fall in the wettest quarter and the average annual temperature were the main factors affecting the distribution of Cordia dichotoma.The suitable distribution area of Cordia dichotoma was mainly located in low-altitude tropical and subtropical areas,and the predicted poten-tial distribution area was larger than the known area at present.Conclusion:Temperature is the decisive factor affecting the distribution of Cordia dichotoma.The results have guiding significance for expanding the planting area and solving the technical problems in the in-troduction process,and also provide data support for the future protection measures of Cordia dichotoma germplasm resources tased on ecological adaptation characteristics.关键词
