摘要
山地城市独特的自然生态条件使得城市空间拓展需要对自然山地环境改造,使之适应城市发展的过程,并由此引发相关的生态效应。认知城市空间拓展与生态环境效应的关系对山地城市的可持续发展尤为重要。在研究分析重庆中心城区空间拓展方式的基础上,总结拓展过程中城市空间结构演变,并通过对城市空间重心点、空间拓展占用景观用地规模,以及中心城区生态服务价值的定量测评,量化阐释了中心城区空间拓展过程中的生态效应,最后提出基于全局的区域拓展格局是山地城市空间拓展的关键。
Transforming the Natural mountain environment is demand to adapt the development of mountainous cities, and causing ecological effect, cognizing the relationship between spatial expansion and ecological efects is particularly important to sustainable development of mountainous cities. Based on the analysis to spatial expansion way of Chongqing central urban area, this article summarized the spatial structure evolution during the expansion process, through the quantitative evaluation to the urban central point, occupy land scale by spatial expansion and ecological service value of Chongqing central urban area, this article quantitative interpreted the ecological efect during the spatial expansion process, finaly put forward urban spatial expansion which is based on the global pattern of regional development is the key to the mountain cities.
