Ecological land can be used to measure the health and safety of the regional ecosystem. Understanding and discussing the spatial and temporal distribution of ecological land use and its formation mechanism have far-reaching significance to the city in formulating land management strategies and guiding the sustainable development. In this article, the land transfer matrix, kernel density estimation, geodetector and ecosystem service value coefficient were used to analyze and discuss the temporal and spatial evolution characteristics of ecological land use, ecological land use and their formation mechanism in Tianjin during 2000-2014. Results showed that: 1)The ecological land in Tianjin showed a continuous decreasing trend, of which New Coastal Region had the most obvious performance, the main target for the transfer of ecological land was construction land. 2)The area of ecological land in Tianjin was concentrated in the north and east, and showed a decreasing trend. 3)The Geodetector results showed that the explanatory power of socio-economic factors on the change of ecological land use was higher than that of natural factors, the three factors with the highest explanatory power were the proportion of primary industry variable rate(0.79), total population change rate(0.73), and proportion of secondary industry variable rate(0.61). The regional industrial structure and population quantity had the strongest influence on the change of ecological land in Tianjin. 4)The dynamic change of ecological land use in Tianjin was negative, and the ecosystem service value decreased year by year. Among them, the value of ecosystem services created by water community was the highest.
