Abstract:

The purpose is to provide theoretical reference and data support for optimizing the allocation of land resources and promoting the sustainable development of regional ecology, society and economy. Based on the construction of the evaluation index system of land use benefit, using the models of coupling coordination degree, relative development degree and obstacle degree, the spatial-temporal evolution characteristics and major influencing factors of the coupling coordination degree of land use ecology-society-economy system in 17 cities of the Shandong Province were explored. The results are as follows. Land use ecology-society-economy system of Shandong was in the primary coordination state of running-in stage and showed a continuous rising trend in 2008-2017. The coupling coordination degree increased steadily from 0.54 to 0.70, and its annual average was 0.63. The equilibrium level of coupling coordination degree among cities was gradually improved in 2008-2017. Its variation coefficient of coupling coordination degree decreased from 0.126 to 0.072, but the coupling coordination degree of land use ecology-society-economy system in different cities still showed an obvious gradient distribution difference from the east to the west of the province. There was a significant difference in the relative development degree among the ecological, social and economic subsystems of land use in different cities. The southern sides of central Shandong and its northern area, together with Weihai City, had constituted an obvious half-circle ecological lag region by 2017. Social and economic barriers affecting the coupling coordinated development of land use ecology, society and economy were dominant throughout, but the ecological impact increased since 2013. During the study period, the coupling coordination level of land use ecology-society-economy system in different cities in Shandong was continuously improved, but the differences among different regions were still obvious, and there was still more space for improvement. Therefore, it is suggested that different cities should consider the main obstacle factors of their own and implement differentiated development strategies according to local conditions.

Key words: land use ecology-society-economy system, coupling coordination degree, relative development degree, obstacle degree, Shandong Province
