Abstract

Prediction of potential vegetation distribution has great significance on protection and restoration of vegetation as a starting point of studies refering to vegetation-climate relationship.On the basis of climate data and current distribution data in Northwest Yunnan,the study predict potential distribution areas of cold-temperate mountainous sclerophyllous evergreen broad-leaved forests by means of Maxent model.Results are as follows:(1) AUC value of training data and texting data are 0.976 and 0.973 respectively,demonstrating that accuracy of the maxent model is excellent.(2) Four climatic factors including Bio6,Bio11,Bio14 and Bio8 become the leading factors affecting the potential distribution of cold-temperate mountainous sclerophyllous evergreen broad-leaved forests in Northwest Yunnan,in which bio6 is the most critical.(3) With a total area of 9 233.92 km2,potential distribution of cold-temperate mountainous sclerophyllous evergreen broad-leaved forests occupy 13.40 percent of Northwest Yunnan.(4)Elevation range of potential distribution areas of cold-temperate mountainous sclerophyllous evergreen broad-leaved forests in Northwest Yunnan is 2 452~4 127m,with an average of 3 034m.

Key words： Maxent model; vegetation-climate relationship; Northwest Yunnan; cold-temperate mountainous sclerophyllous evergreen broad-leaved forests; potential distribution
