Mixed land use is of great significance for improving the efficiency of use of regional land and territorial space. A framework for analyzing and optimizing multi-functional mixed use of construction land based on production-living-ecological space was developed in this study. Based on the point of interest (POI) data, entropy model, landscape pattern analysis, and association rules mining were applied to explore the spatial differentiation of mixed land use, taking Jinan City as the study area. The results show that the main types of mixed use of construction land in the city are production space, production-living space, and living space. The degree of mixed utilization of the core urban area is high, the production and living spaces are concertrated and connected, however, the ecological space is not embedded enough. The landscape fragmentation in the rural areas is obvious, and the mixed use led by production and living space is weak. The living-ecological space in the industrial parks is in a very marginal position in the network. Strengthening the internal planning of the parks or forming a complementary living and ecological space with the surrounding areas is the key to realize the sustainable development of the parks. The research of association rules shows that reasonable production space planning is an important way to guide and optimize the mixed land use. At the same time, strengthening the rational use of ecological space plays an important role in promoting mixed land use. Based on the POI data, this study explored the patterns of multi-functional combination of construction land from the perspective of behavioral spatial interaction theory, which enriches the existing land mixed use theory and methods and provides a theoretical basis for land use policy making and spatial pattern optimization.

Key words: construction land, mixed used, point of interest, grid-based evaluation, landscape ecology, Jinan City
