基于生态足迹的西安城市生态游憩空间优化研究

城市生态游憩空间是进行城市生态游憩活动的重要基础,生态游憩空间的合理配置是生态休闲城市建设的重要内容。基于生态足迹理论模型,构建生态压力指数标准,并结合空间叠加分析法分析了西安市市区生态游憩空间的分布现状以及生态足迹、生态承载力、生态盈亏和生态压力情况。结果表明：西安市市区的人均生态赤字达到了1.4136 hm²/人,生态压力指数为13.2,生态环境状况极不安全;并且区域内生态游憩空间布局和当地的生态环境状况相矛盾。针对西安市生态游憩空间目前存在的问题,对生态游憩空间布局进行优化调整,构建西安市生态游憩廊道系统,对西安市未来城市生态文明建设、城市优质生活环境的塑造和生态安全格局的构建具有重要意义。

Optimization of ecological recreation area in Xi'an city based on ecological footprint

Urban ecological recreation area serves as an important foundation for urban ecological recreation activities. The rational allocation of ecological recreation area is of great significance to build eco-leisure cities. Based on the ecological footprint theory model, combined with the spatial overplay analysis method, this paper constructs the ecological pressure index standard, and analyzes the spatial distribution, the ecological footprint, the ecological carrying capacity, the ecological profit and loss, as well as the ecological pressure of ecological recreation areas in the urban area of Xi'an city. The results show that the ecological environment in urban area of Xi'an is extremely unsafe, with the ecological deficit per capita reaching 1.4136 hm²/person and the ecological pressure index 13.2. The spatial layout of ecological recreation area in the region has conflict with the local ecological environment. To avoid the existing problems, it is of great importance to adjust and optimize the spatial layout of ecological recreation area, and develop the ecological recreation corridor system of Xi'an, in an aim to enhance the urban ecological civilization, and better shape the high-quality urban living environment and the ecological security pattern in the city.
