| 摘 要： | 在科学构建林业有害生物防控综合评价指标体系基础上,运用因子分析和聚类分析法,对31个省进行林业有害生物防控综合评价和分析。结果表明:上海综合水平最高,广西综合水平最低。林业有害生物防控综合水平存在地区不平衡的问题,东部地区较高,中部地区一般,东北和西部地区较低。防治力弱和林业有害生物危害程度高是综合评价生物防控综合水平较低省份的共性问题。

| Abstract: | After scientifically constructing the evaluation index system of forestry pest control,and by factor analysis and cluster analysis,31 provinces of China were taken as examples.The results showed that the Shanghai had the highest comprehensive level and Guangxi had the lowest comprehensive level.Forestry pest control level was uneven in the east-west direction:that was,Eastern China>Central China>Northeast China and western China.Weak control of forest pests and high degree of harmful forest pests were the common problems of provinces with low comprehensive evaluation. |
