摘要
采用传统生态足迹方法与GIS相结合的手段,分析了成都市生态足迹占用压力的空间分布.结果表明：成都市生态足迹压力为0～40 hm^2/hm^2,其空间特征表现为从山地、丘陵到平原依次增加,从中心城区、主城区、郊区依次降低;按照生态足迹压力将成都市分为压力较小区、压力一般区和压力较大区.通过与成都市实际对比以及为了方便管理的需要,将3个生态足迹压力分级分别作为城市发展重点保护区、引导开发区和优化开发区.根据主城区生态足迹压力空间分布特性,指明了成都市中心城区的发展方向,即向东、南发展.
Spatial distribution of ecological footprint pressure of Chengdu City was analyzed with the method of combining traditional methodology and GIS. The results showed that the ecological footprint pressure of Chengdu is among 0 ～ 40 hm^2/hm^2, which were increasing from the mountains to hills and then to the plains while decreasing from the centers to the main and then to the suburbs of the city. According to ecological footprint pressure, three zones were divided： less pressure area, medial pressure area, and larger pressure area, which were made as key zone, guided zone and optimized zone, respectively, after contrasting spatial distribution with the actual situation of Chengdu City and considering the convenience for government management. Based on the characteristic of ecological footprint spatial distribution of main urban areas, it is pointed out that south and east was the optimal development direction to the central urban area of Chengdu City.
