摘　　要：生态足迹法是一种常用的可持续发展度量方法。现有的生态足迹评价方法往往受行政单元的限制,主要从大尺度、宏观的角度开展评价,难以对生态足迹的空间分布进行系统分析,尤其在城市群这样内部差异较大、急需协调发展的地区,评价结果解释和应用更是存在明显的限制。随着遥感数据产品的不断丰富,与生态足迹模型相关的人口、生产性土地面积等指标往往在遥感数据产品中可以定量、定位地表达。该文结合遥感解译获取的NPP、人口密度、土地覆盖等产品,在GIS空间分析技术的支持下,提出了基于格网的生态足迹分析方法;以长江三角洲核心区城市群为研究区,在修正当地产量因子的基础上,估算了研究区2005-2010年公里格网的生态足迹,分析了研究区生态足迹的空间格局。The ecological footprint（EF） method is considered as an approach to measure the sustainable development of environment.However,administrative boundary could be a barrier of existing ecological footprint method.For instance,evaluations are conducted from a large-scale perspective,making it difficult to systematically analyze the spatial distribution of ecological footprint,especially in areas where there are large differences within the urban agglomeration and where there is a great need for coordinated development.There are obvious limitations to the interpretation and application of evaluation results.But continuous enrichment of remote sensing products will provide opportunity for the quantitative analysis of EF in small-scale and can make indicators related to the ecological footprint model accurately.In this paper,a grid-based ecological footprint analysis method was proposed combining with NPP,population density,land cover and other information acquired by remote sensing imagery interpretation and supported by GIS spatial analysis technology.Taking the urban area in the core area of the Yangtze River Delta as the study area,based on the revision of local yield factors,the ecological footprint of the kilometer grid in the study area was estimated from 2005 to 2010,and the spatial pattern of the ecological footprint in the study area was analyzed.
