城市郊区的休闲需求与供给,决定了城市休闲职能的发挥。合理平衡的供给需求关系是休闲产业可持续发展的基础。本文以北京郊区休闲供需关系为研究对象,通过GIS空间分析和空间统计的技术手段,探寻大城市郊区休闲供需的结构、类型和影响因素。以距离衰减规律为设定,北京郊区休闲需求市场规模从380万到1000万之间;而北京休闲供给呈现组团式分布,与圈层式的休闲需求不匹配;通过供需压力指数的计算,北京郊区乡镇可划分为供大于需、供小于需、供需平衡三类;旅游吸引力、水体条件和与城市中心的距离是影响供需压力水平的标志性特征;供需错位会带来出行距离增大、局部地区休闲质量下降、游憩公平不能保证等问题,需要通过产品创新、基础设施改善、分区管理等途径进行优化。本文的研究结果可为城市旅游与休闲规划提供决策支持。

英文摘要：

Urban recreation function is dependent on recreation supply and demand in suburban and rural area. Sustainable development of recreation industry is based on A reasonable balance between supply and demand. This paper aims to explore the spatial structure,types and factors of recreation demand and supply around big cities by spatial analysis and statistics.Recreation demand in suburban and rural area ranges from 3.8 million to 10 million based on distance decay theory. However,the recreation supply, with cluster morphology,does not match the demand spatial form. As a result,the supply-demand pressure index can be calculated and based on which the suburban and rural area can be classified into three types：Over-demand,over-supply and the balance area. Tourism attraction,water conditions and the distance from the city center are the characteristic signs of supply-demand pressure level. The imbalance between supply and demand has several consequences：the increase of trip distance,the decrease of recreation quality and inequality of recreation opportunity. The paper puts forward some suggestions to improve the influences.
