摘要:生态空间是城市群人居环境的重要保障，探析城市群生态空间游憩利用扩展的格局及影响因素，对于完善城市群功能、构建均衡共享的生态空间游憩服务体系具有重要意义。以珠三角城市群为研究区域，从数量和面积两方面分析其在1990-2017年间区域内生态空间游憩利用的动态扩展特征，并探究其影响因素。研究结果表明：（1）生态空间游憩利用的数量扩展方面具有"由少数点向内、外同时扩展→由外向内部分填充"的特征；（2）生态空间游憩利用规模扩展表现出"少数规模较大的孤点→边缘区和建成区内部同时扩展→中心填充"的空间特征；（3）生态空间游憩利用的空间扩展主要受人口增长、城镇化发展、休闲旅游需求变化、区域生态空间治理政策和城市群规划理念的综合影响。本研究总结了城市群生态空间游憩利用扩展规律和成因，启示城市群要通过生态空间治理政策与整体规划的优化推动全域生态空间游憩利用，并注重生态游憩空间配置与人口和城镇化发展、休闲旅游需求变化相协调。



Abstract:Ecological space is an important guarantee of habitat environment in urban agglomeration area. Exploring the spatial expansion pattern and influencing factors of recreational utilization of ecological space (RUoES) in urban agglomeration is helpful to construct a balanced and shared ecological recreation service system, and improve the functions of urban agglomerations. Taking the Pearl River Delta urban agglomeration as the research object, this paper analyzed the spatial expansion characteristics of RUoES from 1990 to 2017 in terms of the spatial quantity and area, and explored their influencing factors. The results showed that:(1) in terms of the expansion of the number of RUoES, it has the spatial characteristics of "expanding from a few points inward and outward at the same time → partially filling from the marginal zone to the core area"; (2) The scale of utilization of ecological space for recreation presents the characteristics of "a few large-scale isolated spots → simultaneous expansion within the marginal area and built-up area → center filling"; (3) The spatial expansion of ESRU is mainly affected by population growth, urbanization, leisure and tourism demand, regional ecological space governance policy and urban agglomeration planning. The current study summarizes the law and causes of the expansion of RUoES in urban agglomerations, and suggests that urban agglomerations should promote the RUoES within the whole region through the optimization of ecological governance policies and overall planning, and pay attention to the coordination of the ecological recreation space allocation with the development of population and urbanization, and changes in leisure tourism demand.
