目前微绿地已成为高密度城市游憩空间拓展主体。为高效响应密集的居民游憩诉求，亟需推动微绿地布局由“个体随机”模式向“组群协同”模式转换。但在高密度环境下，影响微绿地组群布局协同的因素众多且作用方式复杂，有效调控仍是难题。项目在大数据技术支持下，依托协同理论建立序参量方程，对微绿地组群布局协同机理及调控指标展开研究：1）通过多源大数据采集、清洗与校验，从规模结构、环境特征及服务状态三方面建立微绿地组群样本信息库；2）用数据融合法与空间耦合法重构样本规模结构和环境特征信息，形成“组群-环境要素”规模对比和空间关联两类序参量因子指标；3）根据样本服务状态信息测算其服务绩效的总体水平、内部均衡度及趋势一致度，通过CRITIC法融合生成布局协同指数；4）建立序参量方程，带入样本数据探明序参量因子对布局协同指数影响规律，提取主成分因子转译形成组群布局协同调控的关键指标，指导微绿地组群有序规划与协同发展。

The miniature green space has gradually become the main body of outdoor recreational space in development of high density city. In order to efficiently respond to the intensivie recreational demands of residents, the layout formation process of the miniature green space needs to be converted from the “individual random” mode to the “group synergy” mode. In high-density environment, there are many factors affecting the degree of layout synergy of miniature green space group and the action modes are complicate. Therefore, it is still a challenge to make effective regulations in the process of group layout formation. With the support of big data technology, the project builds an order parameter equation based on the synergy theory, and studies the synergetic mechanism and regulation indexes of group layout formation of miniature green space. At first, relying on multi-source big data collection, cleaning and verification, the sample information base of miniature green space groups was established from three aspects: group size and structure, group environment, and service status. Secondly, by reconstructing sample information of group size and structure and group environment with data fusion and spatial coupling methods, two order parameter systems of size matching and spatial compatibility of “miniature green space group - environmental elements” were established. Thirdly, on the basis of information of service status, sample service performance was measured on the aspects of overall level, distribution equilibrium and trend consistency, which were fused into layout synergy indicator by CRITIC method. In the end, order parameter equation was developed to reveal the influence law of the order parameter on the layout synergy index, and the principal component was analyzed and deduced to synergetic regulation indexes of group layout formation of miniature green space. The research results will provide guidance for miniature green space orderly planning and synergetic development.
