| 摘 要： | 松突圆蚧已给我国林业生态环境带来了极大破坏,并造成严重的经济损失.本文选用Maxent生态位模型与地理信息系统相结合,综合分析影响松突圆蚧生长发育的环境因素,结合寄主分布特征,非常直观定量地获得了松突圆蚧在我国的潜在发生区,计算结果经ROC曲线分析法验证,Maxent生态位模型的AUC值为0.991(非常接近于1),表明预测获得了较好的效果,研究可为松突圆蚧的检疫及防治决策的制定提供科学依据.

| Abstract: | Hemiberlesia pitysophila caused destructive disaster for forest ecological environment and huge economic loss in China.Ecological environment factors affecting its growth and development and the spatial distribution characteristics of plant autoeciousness of Hemiberlesia pitysophila were comprehensively analyzed by combining Maxent ecological niche models with geographical information system technique in this paper.The relatively exactly potential distribution region of Hemiberlesia pitysophila in whole Chi... |
