    摘要:

    雄安新区的建设目标是构建"绿色生态宜居新城区",将城市发展与生态宜居并行。生态基础设施作为城市中提供生态系统服务的条件与过程,对构建绿色生态宜居新城区起到主要支撑作用。构建了生态基础设施建设与城市发展的指标体系。在现状分析的基础上,根据雄安新区规划文件,采用地区类比法等方法对生态基础设施建设与城市发展情况进行预测,以形态学空间格局分析(MSPA)模型处理得到的7类景观类型作为生态基础设施指标,并从人口、经济、产业、城镇化4方面构建雄安新区城市发展指标;其次建立耦合协同模型,分析2010、2015、2017、2025、2035、2050年6个年度雄安新区生态基础设施建设与城市发展的协同度水平。研究结果表明,雄安新区生态基础设施建设与城市发展在早期处于濒临失调状态,后续经过政策引导,雄安新区生态基础设施建设与城市发展协同程度逐渐提高,至2050年已达到良好协同状态。研究结果可为促进雄安新区生态基础设施建设与城市协同发展提供科学参考。

    Abstract:

    The construction goal of Xiong'an New Area emphasizes the construction of green ecological livable new city, which parallels urban development with ecological livability. As the condition and process of providing ecosystem services in the city, ecological infrastructure plays a major supporting role in the construction of green ecological livable new city. Therefore, linking the construction of ecological infrastructure with urban development is of great significance to the urban planning, layout and management, and green and high-quality development of Xiong'an New Area in the future. In order to explore synergistic relationship between ecological infrastructure and urban development in Xiong'an New Area, the paper first construct the index system of ecological infrastructure construction and urban development. Based on the analysis of the current situation and the planning documents of Xiong'an New Area, this paper uses the regional analogy method to predict the ecological infrastructure and urban development. Seven landscape types obtained by morphological spatial pattern analysis (MSPA) model are used as the ecological infrastructure indicators, and urban development indicators of Xiong'an New Area were constructed from four aspects of population, economy, industry, and urbanization. Then, the coupling coordination model is established to analyze the coupling coordination degree of ecological infrastructure construction and urban development in Xiong'an New Area in 2010, 2015, 2017, 2025, 2035 and 2050. The research results show that the ecological infrastructure landscape is highly fragmented and poorly connected, and the ecological infrastructure construction and urban development are on the verge of maladjustment during the early stage in Xiong'an New Area. After the policy guidance, the coordination between ecological infrastructure construction and urban development in Xiong'an New Area is getting better, and it will reach a good coordination state in 2050. The research results can provide scientific reference for promoting the coordinated development of ecological infrastructure construction and urban development in Xiong'an New Area. Finally, based on the existing analysis results of the paper, the following suggestions for the planning and construction of ecological infrastructure in Xiong'an New Area were put forward:(1) Xiong'an New Area needs to build a multi-level ecological corridor from Baiyangdian to Daqing River Basin; (2) Speed up the construction of short-term and medium-term ecological infrastructure and optimize the long-term ecological infrastructure planning; (3) In the future, residents' wishes should be integrated into ecological infrastructure planning and construction.
