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.
