- 摘要:
- 应用最大熵模型MaxEnt和地理信息系统ArcGIS,预测了合欢在我国的潜在适生区及其适生等级,为明确合欢在中国的潜在分布区和适宜性,及开展合欢种植区划和规范化栽培提供指导。结果表明:合欢潜在分布区主要位于华中、华南、华东和西南部分地区,主要适生省份为贵州、广西、广东、湖南、湖北、福建、江西、浙江、安徽(适生指数>0.7);刀切法测试表明,最暖季降水量(模拟贡献率26.3%)、7月降雨量(25.2%)、年均温(13.5%)、最干季平均温(11.6%)、1月平均气温(10.8%)是影响合欢潜在分布的最主要5个环境因子。合欢最适生长地区主要集中在华中、华东2个地区。
- Abstract:
- The potential distribution prediction and suitability evaluation of Albizia julibrissin Durazz.were conducted which based on MaxEnt and ArcGIS,in order to grasp the potential distribution and suitability,to provide valuable references for the plantation regionalization,and the standard cultivation of A.julibrissin.The results indicated that the model revealed that the potential distribution areas were mainly in parts of central China,eastern China,south China and southwest China.Within these areas,Guizhou,Guangxi,Guangdong,Hunan,Hubei,Fujian,Jiangxi,Zhejiang,Anhui were determined as the largest highly potential distribution areas (suitability index>0.7);a jackknife tested in MaxEnt suggested that was precipitation of the warmest quarter (contribution percent,26.3%),precipitation of July(25.2%),annual mean temperature (13.5%),mean temperature of the driest quarter(11.6%),mean temperature of January(10.8%)were the main influential environmental factors that affecting the distribution of A.julibrissin. The potential distribution areas of A.julibrissin were mainly concentrated in central China and eastern China.
