摘要
【目的】探究甘肃省土地利用演变规律和驱动机制。【方法】基于“三生”视角构建土地利用功能综合评价指标体系,对甘肃省86个县域单元2010~2020年间土地利用功能时空分异特征进行综合测度,并利用空间回归模型确定各土地利用功能空间分布驱动因素。【结果】研究期间,甘肃省生产、生活功能持续改善,地域集聚趋势明显,生态功能保持动态稳定。生产和生活功能高值区均呈现围绕各中心城市分布、生态功能高值区沿青藏高原边缘及秦岭西延伸段分布的特征。甘肃省县域“三生”功能耦合协调度整体较高且呈现不断改善趋势。生产与生活功能表现为协同关系,生态与生产、生活功能表现为权衡关系,三对关系在研究时间段均呈现相对稳定态势。城镇化率等因素对生产和生活功能有着显著的正向作用,植被覆盖率对生态功能具有显著正向作用。【结论】本研究结果与区域经济社会发展进程有较强的吻合性,“点带状”分布格局与甘肃省推动的“一核三带”发展格局相契合。
【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 comprehensive 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 functions 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 coordination degree of"production-living-ecological"function is higher and shows a trend of continuous improvement.The function of production and life shows a synergistic relationship,while the function of ecology,production 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 urbanization rate have significant positive effects on the production and living functions,and vegetation coverage has significant positive effects on ecological functions.【Conclusion】The results are in strong agreement 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.
