基于遥感数据的厦门市生态绿地多样性分析

以遥感数据为基础。在地理信息系统的辅助下，运用生态学原理，选取厦门市湖里区作为研究区域，以鼓浪屿为比较，结合具体情况和考虑研究的可操作性，以绿地斑块大小来进行分类，选取多样性指数、优势度、均匀度3个指标，对厦门市湖里区及鼓浪屿城市植被景观进行多样性分析。研究结果表明：湖里区绿地景观多样性指数为1．844。优势度为0．510，均匀度为0．741；鼓浪屿绿地景观多样性指数为2．190，优势度为0．847，均匀度为0．395。两区总体表现为各类型分布不均，各种类型相差较大，多样性程度不高。综合评价结果为鼓浪屿区较湖里区合理。

RS-based Analysis of Ecology Greenland Variety in Xiamen City

This paper takes the remote sensing data as the foundation,in geographic information systems(GIS) support,using ecology principle,selected Huli District in area Xiamen City as a study area,takes Gulangyu as the comparison,unifies the special details and the consideration research feasibility,carries on the classification by the green space mottling size,selection multiple index,superiority,uniformity,the three targets,the area city vegetation landscape carries on the multiple analysis to Huli District in Xiamen City and Gulangyu District.The results indicate:the landscape diversity of Gulangyu District was 2.190,which was higher than Huli District(1.844),and the dominance of Gulangyu District was higher than Huli district(0.510),which indicates one kind of greenbelt type was prepondenderant in this district and the greenbelt types of Huli district was comparatively proportional.The uniformity of Huli District was higher than Gulangyu District(0.395).Fuzzy comprehensive assessment method was used to evaluate greenbelt landscape with indices of urban greenbelt landscape structure and green overlay;the results indicates the ecology greenland variety in Gulangyu District has the most desirable and that in Huli District has the least desirable structure.
