| 摘 要： | 利用2006年勐腊县森林资源二类调查数据，在ARCGIS9和FRAGSTAT3．3软件支持下，选取有代表性的林地景观格局指标：景观斑块密度、分维数、聚集度、破碎化、多样性指数、优势度、均匀度等来描述勐腊县林地景观格局。结果显示研究区优势度较低，异质性不高；景观中有一定的优势类型，以自然景观占优势。橡胶林景现破碎化程度较低，斑块较为完整。混交林景观连通性好，结构稳定。半自然景观、农地景观破碎化程度较高。

| Abstract: | The representative setup indicators such as landscape patch density, fragility, diversity, dominance, evenness and etc. were selected to describe the landscape setup of Mengla countyg forested land by means of data of forest resource inventory and planning supported by ARCGIS 9 and FRAGSTAT 3.3 software in 2006. The result revealed that the dominance was comparative low in study area, while natural landscape was dominant among certain dominant types. Fragmental extent of rubber forest landscape was low and patches were relative integrated, but that of semi-natural landscape and farmland landscape was high. The structure of mingled forest is stable. |
