| 摘 要： | 在总结了中国森林资源连续清查体系现状的基础上,以吉林省第7次森林资源连续清查固定样地资料和吉林省TM遥感影像为基础,对固定样地调查结果与遥感影像分类结果进行了对比,并采用点对点匹配法,分析了固定样地作为遥感影像解译标志时的精度.结果表明,采用固定样地调查与遥感影像分类调查森林资源总体精度较高,森林覆盖率误差仅为-1.04%,而点对点匹配检验时森林类型误差达到52.99%.

| Abstract: | Based on summary of the national forest inventory of China,using permanent sample plot data of the seventh national forest inventory in Jilin Province,this paper compared the results of permanent sample plot inventory with the results of classification by remote sensing images,and analyzed the accuracy of interpretation using the matching method of point to point from permanent sample plot to classification map.The results showed that the forest resources inventory error was low both using permanent sample plot and remote sensing classification,the accuracy of forest coverage rate was-1.04%,but the interpretation error was 52.99%. |
