Spatial-Temporal evolution of land use and its influencing factors from the perspective of production-living-ecological function in Gansu Province
[Objective]In this study,to explore the laws and driving mechanism of land use evolution in Gansu Province.[Method]Based on the perspective of production-living-ecological function,a comprehen-sive evaluation index system of land use function was constructed,and the methods of trade-off and synergy analysis were applied to comprehensively measure the temporal and spatial differentiation characteristics of land use function in 86 county units of Gansu province from 2010 to 2020.Meanwhile,the spatial regression model was used to determine the factors affecting the spatial distribution of each land use function.[Result]The research results show that(1)during the study period,the production and living functions of Gansu province are continuously improved,the trend of regional agglomeration is obvious and the ecological func-tions remain dynamic and stable.The high values of production and living functions are distributed around the central cities,and the high values of ecological functions are distributed along the edge of the Qinghai-Tibet plateau and the western extension of the Qinlin mountains.(2)In Gansu Province,the coupling coordi-nation degree of"production-living-ecological"function is higher and shows a trend of continuous improve-ment.The function of production and life shows a synergistic relationship,while the function of ecology,pro-duction and life shows a trade-off relationship.The three pairs of relationships show a relatively stable trend in the study period.(3)Social and economic factors such as the ratio of public budget to expenditure and ur-banization rate have significant positive effects on the production and living functions,and vegetation cover-age has significant positive effects on ecological functions.[Conclusion]The results are in strong agree-ment with the regional economic and social development process.The"point-zonal"distribution pattern is consistent with the"one core and three belts"development pattern promoted by Gansu Province.
