摘要：以江西省武宁县林改前后（2000年和2008年）2期TM遥感影像为基本资料,运用空间分析和统计分析方法,从林地类型及转换、植被覆盖度和森林景观指数等3个方面,对研究区林改前后林地资源变化特征进行分析。结果表明,1）阔叶林、针叶林和毛竹林显著增加;灌木林、疏林地和无林地显著减少。林地与非林地间转换不多,但林地内部转换数量和频率均较大。林改后针叶林（占34.93%）为全市最大的优势地类,转入率最高的为阔叶林,转出率最高的为疏林地;2）武宁县植被覆盖度主要分布在0.4~1.0之间（超过83%）,林改后0.6~1.0的分布区间面积增加;3）景观特征指数分析表明,林改后武宁县多样性指数、边缘密度和总斑块数下降,景观水平趋于均一化;斑块特征指数分析表明,乔木林斑块数、分散度和破碎度均降低。毛竹林斑块数增加,分散度降低,但破碎度不变。林改后武宁县林农营林积极性增强,使得有林地面积和植被覆盖度增加,景观向良性发展。
This paper analyzed the change characters of wood land resources of Wuning County,Jiangxi Province by using spatial analysis and statistical techniques,from land use and its conversion pattern,vegetation fraction and landscape index three aspects based on 2000 and 2008Landsat TM remote sensing images.The results showed：1）broad-leaved forest,coniferous forest and bamboo plantation areas increased significantly,sparse forest,shrubbery and non-forest areas decreased obviously.The major changes of land use were the conversion between wood lands,but not between the wood land and the non-wood land.The coniferous forest became the dominant class type（34.93% of the total area）,meanwhile the broadleaved forest had the highest transfer-in rate and the sparse forest had the highest transfer-out rate.2）Vegetation fraction degree was mainly distributed between 0.4~1.0（more than 83% of the total area）and vegetation fraction degree distribution from 0.6~1.0 area increased after collective-owned forest tenure reform.3）The analysis of landscape characteristics index showed that the landscape diversity index,edge density index and total patch number decreased,indicating that the landscape level tended to be uniform.The analysis of plaque characteristics index showed that the broad-leaved forest and coniferous forest plaque number,dispersion degree and fragmentation degree also decreased,the bamboo forest plaque number increased,dispersion degree decreased and fragmentation degree didn＇t change.The conclusion was that forest farmer silvicultural enthusiasm was enhanced,which brought forest land area and vegetation fraction degree improving,the Wuning County landscape was being lead to a good direction after the collective-owned forest tenure.
