摘要
简要介绍了生态城市的概念和城市生态系统的内涵。评价了兰州市的城市生态建设的相关指标,指出:生态兰州建设已经取得了巨大成就;但由于兰州自然环境系统的"先天不足"和"先天性缺陷"、人工物质系统建设成本过大和基础薄弱,生态兰州建设面临整体方向的选择。认为基于GIS空间分析和网络分析技术的城镇体系建设是建设生态兰州的重要方向。
This paper introduces the meanning of eco-city and city ecology system simply. Then some indexes of the eco-city costruction are estimated for the Lanzhou city. There are great achievements for the Lnazhou ecologic construction. But Lanzhou nature environment system has its shortcoming, which results in bigger costruction cost of the artificial material system and worse basis. So to construct eco-city Lanzhou would face the seletion of holiotic direction. This paper sugguests that the costruction of city and town system is the important direction of Lanzhou eco-city construction. Based on GIS, We describe the conformation of the construction of city and town system.
