住区休憩空间是城市生活最贴近居民的日常生活空间。在紧凑城市和社区重构理念影响下，珠三角紧凑型住区的休憩空间模式日益出现丰富多样的形态和结构变化，需要对其基本模式和发展方向做前瞻性研究，尤其需要应对休憩空间"数量"、质量和整体空间协同效益不足带来的挑战。 由于缺乏对珠三角紧凑型住区休憩空间的数量、质量和空间协同效益的量化研究，不能准确反映其真实价值，使休憩空间设计缺乏理论、数据支持和规划指标管控"失灵"的情况。 本课题从反映休憩空间质量的功能指数的量化研究入手，结合可达性分析得出空间价值的折减系数，进一步引入协同系数反映休憩空间分布的协同效益，建立住区休憩空间价值的整体量化模型。 课题以环境行为学和环境评价理论为基础，强调文献研究和国内外案例调研紧密结合，运用PSPL调研法和其它技术工具，结合实测、模拟、GIS技术等，采用居民行为心理测量方法，运用多种专家评价方法进行综合研究和相互印证。

Neighbourhood recreational space is the urban environment which has the closest connection with people. Under the thoughts of compact city and neighbourhood reconstruction, there have been variety of rich forms and structures for recreational space in compact neighbourhoods in the Pearl River Delta (PRD). It is a practical and prospective study to explore its basic patterns and future development, especially need to face challenges of the lack of quantity, quality and total synergy of the neighbourhood recreational space. Just because the lack of quantitative research for quantity, quality and total synergy of the neighbourhood recreational space in compact neighbourhoods in PRD,the value of recreational space can't be clearly reflected. That caused the lack of theoretical and data support for planning and design, and failure for some of the planning control indexes also. This research,start from the quantitative study of functional quality index which reflect the value of recreational space, combined accessibility study to reach the reduction coefficient of the recreational space value. Synergy index is led to reflect synergy benefits of distribution and arrangements for recreational space further, so that the quantitative evaluation model can be established to reflect total recreational space value. This research has close association with the following characters: (1) environment-behavior study and theory of environment evaluation; (2) close link between literature review and study cases at home and abroad; (3) application of PSPL method and other new technical instruments; (4) application of actual measurement, computer simulation and technology of VR & GIS; (5) measurement methods of resident's subjective evaluation;(6) evaluation methods of experts; (7) compositive comparison and reciprocal verification.
