Abstract: This paper reveals the spatial-temporal correlation characteristics and coordination/trade-off relationship of the "production-living-ecological" functions in the county of Jiangsu province, which can provide theoretical support for the spatial planning of the county. Based on the theory of "production-living-ecological" spatial superior group and niche situation theory, this paper constructs the function recognition system of land space from three dimensions of production, life and ecology. The spatial autocorrelation and correlation coefficient method were used to quantitatively measure the time effect and coordination/trade-off relationship of the "production-living-ecological" function in Jiangsu province in 1996, 2005 and 2015. The results were obtained as follows: (1) The niche width of "production-living-ecological" functions in Jiangsu was varied, and its spatial distribution had its own characteristics. The specific manifestation was that the niche width of production function had a general increasing trend in the period 1996-2015, but the changing process had the stage characteristic, presenting a pattern of "high in the south high but low in the north", the south bank of the Yangtze River was in strips distribution, and the north bank was multi-aggregated. From 1996 to 2015, the niche breadth of life function was continuously compressed, and the space was attenuated by the concentric circle centered on the municipal area. In the same period, the ecological function niche width increased continuously, the ecological functional niche breadth in space has high value near the mountain and water. (2) From 1996 to 2015, the three functions of production, life and ecology in this province had positive correlation type (HH, LL) clustering obviously, presenting a "group" type distribution with the change of time. On the contrary, negative correlation type (HL, LH) with low agglomeration, showing a "discrete" distribution. (3) Production and life function had spatial synergistic relationship, and production and ecological functions showed a coordination/trade-off fluctuations. The changing trend of life function and ecological function was similar to the production and ecological function with more obvious change, and the coordination/trade-off relationship in different years had obvious differences in different units. Studies have shown that all of the above characteristics were in good agreement with regional economic and social development. In the future, we should gradually change the phenomenon of production function expansion and compression of life and ecological functions, so as to protect the ecological environment and to improve the quality of life oriented coordinated and optimized development path.
