中文摘要：

以2010年将乐县林相图为源数据,从2个等级对森林景观类型进行划分,利用分形理论对研究区内各景观斑块类型指标、形状指标和异质性指标进行定量分析,并讨论景观结构的分形特征.结果表明,研究区以有林地和非林地为主,二者面积比重之和高达97.174%,且斑块被边界割裂的程度较高.异质性分析表明,将乐县景观斑块团聚程度较高、结构组成复杂且具有良好的连续性,景观异质性程度较高,但各斑块类型空间分布不均匀.景观要素的分维数及稳定性分析表明,非林地的斑块形状复杂程度较高,灌木林地、其它林地和有林地的空间结构稳定性较好,其稳定性指数值均高于全县的稳定性指数值0.291.有林地中竹混交林的斑块形状最为规则且稳定好,而针叶纯林的斑块形状最为复杂且稳定性差.

英文摘要：

This thesis took the 2010 stock map of Jiangle County as source data,dividing it from two grades of the forest landscape types,and comprehensively uses the GIS and Fragstats software and fractal theory to have a quantitative analysis on the study area ’s landscape patch type indicators,shape indexes and heterogeneity indexes,and discussed the fractal features of landscape structure. The results showed that the study area is based of forest and non forest,the proportion of the sum of the two areas is 97. 174%,and the degree of patches which is fragmented by boundaries is high. Heterogeneity analysis showed that the reunion ’s degree of landscape patches in Jiangle county is higher. It has a complex composition,a good continuity and a higher degree of landscape heterogeneity,but the various types have a uneven distribution in the patches of the study area. Fractal dimension and stability analysis of landscape elements shows a high complex degree of the shape of no-forest-patches. Shrub land,other woodland and forest land have a better structural stability space,and their stability index are 0. 291 higher than the county’s stability index. The shape of patches of the bamboo mixed forest in woodland is most regular and stable,and the shape of patches of the coniferous forest is most complex and lack of stability.
