摘要
快速的城市化进程使生态环境问题与群众活动需求问题日益凸显,以保护生态环境为基础,提出城市型森林公园规划布局优化方法。利用服务面积占比与服务人口占比等指标,分析森林公园可达性,分别计算各因子权值并完成适宜度等级划分,划分布局整体生态环境适宜性等级,依据建立的可达性指标与各生态适宜因子指标,结合GIS分析结果制定平衡生态环境与服务需求的布局优化方案。经过对比发现所提优化方法大幅提升了可达性指数,使服务价值得到进一步加强,且有效改善了园区生态环境质量。
The rapid urbanization process has increasingly highlighted the problems of ecological environment and the needs of mass activities.Based on the protection of the ecological environment,an optimization method for the planning and layout of urban forest parks has been proposed.The study analyzed the accessibility of the forest park using indicators such as the proportion of service area and the proportion of population served,calculate the weights of each factor and complete the suitability grade division.It divided the overall ecological environment suitability grades based on the established accessibility indexes.Each ecological fitness factor index is combined with GIS analysis results to formulate a layout optimization plan that balances the ecological environment and service demand.After comparison,it is found that the proposed optimization method has greatly improved the accessibility index,further strengthened the service value,and effectively improved the ecological environment quality of the park.
