摘要/Abstract

摘要： 利用多元线性回归分析法建立了江苏宿迁市2000年、2005年、2010年森林蓄积量和郁闭度估测模型，采用基于遥感数据的森林信息提取方法，结合主成分分析法与逐步回归法判断最优模型，对估测森林蓄积量后的验证发现，最优模型精度能达到96%以上，基本满足估测要求。而根据宿迁市3期郁闭度和森林蓄积量结果分级统计表明，宿迁森林蓄积量在近10 a 内逐年稳步上升。

Abstract: By using multivariate linear regression method, estimation model of forest volume and crown closure in the three years, 2000, 2005 and 2010 over the entire Suqian city were established in this paper. The method of mining forest information was used to determine the optimal combination estimation model with implementing the principal component analysis and the stepwise regression method based on Landsat TM. According to the statistic of validating estimate model, the result of the estimation was relatively accurate and could satisfy the requirement basically, which was more than 96%. Grading the crown closure and forest volume showed that there was a progressive improvement in Suqian′s forest resources of three periods. A continuous increase of forest volume, implied a good sign of ecological functioning in Suqian.
