| 摘 要： | 土地利用多功能性识别是城市用地组织,协调与配置的基础信息源,是判定城市用地内在功能形态,功能组合模式和功能之间动态权衡的关键,具有重要的理论和实践意义,但长期以来并未构建一套可行的识别方法体系.本文从土地功能,生态系统服务和景观功能综合的视角构建城市生态--生产--生活空间功能分类体系,并以生态系统服务价值评估为基础系统整合空间功能价值量核算函数群,通过纵横对比的方法确定空间功能主导类型.研究区实证分析表明,城市生态--生产--生活功能分类体系较好反映了不同地类的功能类型;空间主导功能的识别也与不同地类的功能匹配;同时也发现三生空间的整体毗邻性较低,空间功能的互补和融合性较差的问题;三生空间功能存在一定的空间集聚性.

| Abstract: | The identifying of land multifunctionality is a basic tool for organization, coordination and configuration of urban land, and is a key criterion for urban land functions forms, composite pattern and dynamic tradeoffs. This topic is of important theoretical and practical significance. An available identification system of urban land multifunctionality, however, had not been built for a long time. This paper develops a function classification system for urban ecological-production-living spaces from an integrated perspective of land function, ecosystem services and landscape function. We integrated a value function group of space function based on ecosystem services valuation. A comparison method of vertical and cross direction is proposed to identify dominant function type of urban land. The empirical results show that in the study area, function classification system of urban ecological-production-living spaces can reflect differentiated function types of different land use classes. The identified result of dominant function for urban space is matched with the functions of different land types. Meanwhile, we also found that there are some problems on urban land use, such as the low adjacency degree with different spaces, and poor complementarity with different space functions. The result indicates that the spatial distribution of urban ecological-production-living spaces is congregated in the study area. |
