基于遥感数据的生态脆弱区森林景观分类及格局研究——以香格里拉为例

Research on Classification and Pattern of Forest Landscape of Ecological Fragile Region Based on Remote Sensing Images——A Case Study of Shangrila

以Landsat-7 ETM+为数据源,在遥感(RS)和地理信息系统(GIS)技术的支持下,对云南省香格里拉县北部进行森林景观分类及其景观结构分析。结果表明,研究区以针叶林为主要森林景观,阔叶混交林的形状结构较为松散,景观破碎化程度最严重,人为干扰强烈。因此,需加强森林保护,减少人为干扰,防止景观破碎化程度的进一步加深。

In this paper,the data souxce was Landsat - 7 ETM ＋ ,remote sensing（RS） and geographic information systems （GIS） technology in support of northern of Shangrila County forest landscape classification and landscape structure analysis. The results showed that in file study area the coniferous forests was as the main forest landscape,and broad- leaved mixed forest shape index was more loose,easy to interaction between internal and external environment,but this regional fragmentation was the most serious,human disturbance was the most strong, we needed to strengthen forest protection,and prevent the degree of landscape fragmentation further deepen.
