基于卫星遥感的城市绿地景观格局变化研究进展

城市绿地景观是城市景观自然要素和社会经济可持续发展的生态基础,在城市景观结构、功能及其变化中起重要作用。利用卫星遥感技术开展城市绿地格局研究已成为热点。本文通过梳理相关研究成果,阐述了城市绿地景观遥感分类方法、景观格局指数的选择及城市绿地景观格局动态变化驱动力分析的具体内容,分析出基于遥感技术的城市绿地景观格局研究在数据源和景观格局指数选择时所存在的不足,并且从遥感数据源、分类方法、景观指数筛选和多学科、多角度交叉综合的研究方法等方面对城市绿地景观格局分析提出展望。

Research progress of urban green space landscape pattern change based on satellite remote sensing

Urban green space landscape is the ecological basis for the natural elements of urban landscape and the sustainable development of social economy,which plays an important role in the structure,function and change of urban landscape.Using satellite remote sensing technology to study urban green space pattern has become a hot spot.By reading and organizing the relevant literatures,this study expounds the remote sensing classification method of urban green space landscape,the selection of landscape pattern index,and the specific content of driving force analysis of urban green space landscape pattern dynamic change.The results shows that there are some deficiencies in the data source and landscape pattern index selection of urban green space landscape pattern research based on remote sensing technology.This study puts forward to the prospect of urban green space landscape pattern analysis from the aspects of remote sensing data sources,classification methods,landscape index selection,and multidisciplinary and multi-angle cross-synthesis research method
