基于遥感技术的滁州市各县森林线性优化配置分析

Linear Programming and Optional Distribution of the Forest Resources from Counties in Chuzhou Based on Remote Sensing

森林植被作为土地覆盖的重要类型之一,在社会、经济、文化和环境中的地位与其所发挥的生态效应相关,对耕地、园地等水土流失区保护就具有重要意义。文章利用遥感影像和一些数学方法来优化配置森林资源,以2000年、2006年相近的滁州市TM遥感影像作为数据源,利用监督分类法对森林植被进行分类、统计、验证和分析,结合层次分析法和线性规划法对森林植被分布进行优化。结果表明定远县、凤阳县、来安县、天长市各县市森林植被配置不合理,需要各增加476.74km2、255.41km2、162.76km2、263.49km2,适当增加农田林网建设,这样才有利于各县市农林生态和谐发展。

Forest resources are one of the best important type of the land cover. It related to standing and ecological effect from forest resources in the social, economics, culture and environment. It is very important to optimize the distribution of forest resource for water and soil conservation on the regional scale based on remote sensing images and mathematical methods. In this study, two periods （2000 and 2006） of TM remote sensing images with similar temporal phase were selected as the basic data sources. The supervised classification was used for classification, statistics, verification and analysis of the forest resources with the AHP and the optional distribution method. The results indicated that the forest resources spatial distribution was extremely uneven in Dingyuan, Fengyang,Laian,and Tianchang,their needs should be increased by 476.74km^2,255.41km^2,162.76km^2,263.49km^2. Therefore, the appropriate increase of farmland shelterbelt construction is conducive to the harmonious development of agriculture and forestry ecological county.
