摘要:
 城市绿地可达性是影响其使用效率的重要因素,也是城市绿地建设合理性的重要标志。以沈阳市为例,在考虑城市居住用地类型及人口空间分布的基础上,基于QuickBird卫星遥感数据和GIS空间分析技术,采用基于人口权重的人口重心模型,定量表征与模拟研究区绿地优化格局,并结合缓冲区分析方法对绿地格局优化结果进行了定量分析与评价。结果表明,城市公园绿地面积增幅为39.9%的情况下城市公园绿地可达人口增加了104.7%,优化方案中86.5%的居民均可实现500 m可见绿地的目标,通过优化实现了以较少的绿地面积发挥较大的绿地效益。可为城市绿地系统规划提供科学的决策依据与参考。
Abstract:
 Green space accessibility is an important indicator to evaluate the rationality of green land construction.Taking Shenyang as an example,based on QuickBird imagery and GIS,optimal green land pattern of residential types were quantitatively described and simulated by applying population gravity center model.The results were quantitatively analyzed and evaluated by buffer analysis method.It was found out that when the area of urban parks increased by 39.9%,residents who could access the parks increased by 104.7%.In the optimization plan,residents could access green land within 500 m of their residences,by which limited green spaces could make the greatest benefits for local people.The results of this study would provide references for the scientific decision making for administrators.
