【摘要】：准确认知并促进城市人口与森林之间的和谐关系,是建设和谐宜居城市的重要内容。文章以北京建设国际一流的和谐宜居之都为背景,在分析森林覆盖率与人口密度关系的基础上,通过构建人林和谐度评价方法,对北京各区及4大功能区的人林和谐度进行了评价研究。结果表明,从总体上来看,不同区的森林覆盖率随着人口密度的增加而呈乘幂式减少;人林和谐度也表现为从生态涵养发展区、城市发展新区,到城市功能拓展区、首都功能核心区的依次递减趋势,其中人林和谐度处于Ⅰ级的有延庆、怀柔、门头沟、平谷和密云,而西城、东城则处在Ⅳ级的水平。为解决各区之间人林和谐度严重不平衡的问题,建议充分结合各区具体情况,合理运用疏解人口、造林增绿两大举措,推进北京国际一流的和谐宜居之都建设。
