| 摘 要： | 珠海是珠江三角洲地区一个海陆交互作用与人类干扰活动频繁的典型区域。文章以2000年TM数据为基础数据源，编制珠海地区景观类型图，并以镇(区)为基本空间单元将珠海划分为20个景观生态子区，在GIS与景观斑块分析软件Patch Analyst 2．0支持下计算各子区的景观特征指数。通过各子区的景观指数对比分析，探讨研究区范围内景观格局的空间差异，揭示人类活动、自然干扰等各种景观生态机制对区域景观生态的影响。根据各指数反映的景观特征信息，选择平均斑块大小(MPS)、斑块大小变异系数(PSCOV)、边缘密度(ED)、面积加权分维数(AWMPFD)、破碎度指数(F)、多样性指数(SDI)及人为干扰指数(DT)进行珠海景观生态聚类分析，根据聚类分析结果可多层次客观地对珠海地区进行景观生态类型区划分。 |

| Abstract: | Base on TM (2000) remote sensing data, landscape types map of Zhuhai had been compiled. According to administrative regionalization, Zhuhai area was divided into 20 basic landscape ecological units. And landscape index of every unit were calculated with GIS and landscape patch analysis software. By analysis of landscape index and spatial changes of landscape pattern, human active and natural disturbance effect on regional landscape ecology were also discussed in this paper. Landscape ecological cluster analysis of Zhuhai was implemented by choosing some landscape index including MPS, PSCOV, ED, AWMPFD, F, SDI and DT. The results can be used for landscape ecological classification in difference levels impersonally. |
| Keywords: | Landscape Index landscape ecological zone classification Cluster Analysis Zhuhai |
