摘　　要：蓝绿协同是城市水文与绿地之间在规模与分布上相匹配后形成的结构和功能上的互补互促作用,是当前解决城市旱涝多发、用水失衡、生境退化问题的重要突破口。研究提出蓝绿协同度的概念,建立蓝绿协同度的评价模型与指标体系,提出蓝绿协同度的制图方法,并以西安市城乡交错带为研究对象实现了基于蓝绿协同度评价的绿地格局优化方案的生成,优化后蓝绿协同度较低及以下区域的蓝绿协同度升高到0.30,达到中等水平,证明了优化方法的可行性。同时,运用该优化方法对西安高铁东站规划核心区开展设计实践,实现了蓝绿问题治理与城市景观构建的有机结合。研究可为蓝绿协同效应研究及在城乡复杂环境下开展蓝绿空间规划和生态建设提供新的思路,为城市绿地规划方法的优化改进研究提供参考。The blue-green synergy is an effect of complementary and mutual promotion in structure and function between hydrology and green space,matching size and distribution.The blue-green synergy is an important breakthrough to solve the problems of urban drought and food,water use imbalance,and habitat degradation.The concept of blue-green synergy degree is proposed,and its evaluation model and indicator system are established.A mapping method for the blue-green synergy degree is proposed.Taking the rural-urban fringes of Xi’an city as the object,the optimization scheme of the green space pattern was generated based on the evaluation of the blue-green synergy degree.The results show that the blue-green synergy degree increased to 0.30 in areas with lower blue-green synergy degrees after optimization,which reached a moderate level,proving the feasibility of the optimization method.At the same time,the optimization method is applied to design the core planning area of Xi’an high-speed railway east station,realizing the organic combination of blue-green problem governance and urban landscape construction.The research can provide a new idea for the study of the synergistic effect of hydrology and green space and the development of the blue-green spatial planning and ecological construction in the complex urban and rural environment.This research can also provide a reference for optimizing and improving urban green space planning methods.
