| 摘 要： | 文章以鄂尔多斯市2001～2009年森林资源调查数据为材料,对森林总面积、森林覆盖率、森林蓄积量、组成结构等进行了动态分析,并做出了各项森林指标间的线性回归方程。结果表明,2001年以来,森林总面积、森林覆盖率和森林蓄积量均稳步提升,年均增长速度分别为8.28万hm2、0.95%和33.7万m3。森林覆盖率与灌木林地面积、森林蓄积量与有林地面积有显著相关性,回归方程分别为y=0.1199x+2.4778(R2=0.9999)和y=10.003x2-439.31x+5471.7(R2=0.9071)。

| Abstract: | Based on the date of Forest resources of Ordos in 2001 to 2009,we conducted dynamic analysis on acreage,coverage and volumes of the forest resources.The results showed that the forest acreage,coverage and volumes have been all greatly improved.The average annual increasing rate of forest acreage was 82800hm2,The average annual increasing rate of forest coverage was 0.95%,the average annual increasing rate of forest volumes was 337000m3.There was Significant correlations between forest coverage and acreage of shrub,between forest volumes and acreage of woodlands.The linear regression equation was y=0.1199x+2.4778(R2=0.9999)and y=10.003x2-439.31x+5471.7(R2=0.9071) |
