    摘要:

    [目的] 探究浙江省县(市)域土地利用效率演变与优化机制,为实现土地资源高效优配提供对策和建议。[方法] 综合运用SBM-Undesirable模型、熵值法、自然断点法和地理探测器模型,探究2007—2018年浙江省69个县(市)域的土地利用效率演变特征及优化机制。[结果] ①浙江省县(市)域土地利用效率演变呈明显的“三阶段”特征,县(市)域差异持续缩小,并呈现“东高西低”的空间分异态势;根据2018年县(市)域土地利用效率分类,可将浙江省划分为高效率、中高效率、中等效率和低效率4类分区。②2007,2012和2018年,浙江省县(市)域土地利用效率的重要驱动因素分别为资本投入规模、资源环境规制和科技创新能力;2018年,各驱动因素对不同分区县(市)域土地利用效率的作用存在较大差异。③基于2018年县(市)域土地利用效率及其驱动因素特征,在遵循“效率优先”原则的基础上,提出针对不同分区的土地管控政策,并制订差异化的土地利用优化策略。[结论] 浙江省土地利用效率及其驱动因素具有明显的时空异质性,科技创新能力为现阶段首要驱动因素。

    Abstract:

    [Objective] The evolution and optimization mechanism of land use efficiency of counties (cities) in Zhejiang Province were analyzed in order to provide suggestions on realizing efficient and optimal allocation of land resources.[Methods] Using SBM-Undesirable model, entropy method, natural breakpoint method and geographical detector model, the evolution characteristics and optimization mechanism of land use efficiency of 69 counties (cities) in Zhejiang Province from 2007 to 2018 were studied.[Results] ① The evolution of land use efficiency of counties (cities) in Zhejiang Province was characterized by "three stages", and the difference between counties continued to narrow, showing a spatial differentiation trend of "high in the east and low in the west". According to the classification of land use efficiency of counties (cities) in 2018, Zhejiang Province could be divided into four zones:high efficiency, medium efficiency, medium efficiency and low efficiency. ② In 2007, 2012 and 2018, the importent driving factors of land use efficiency of counties (cities) in Zhejiang Province were the scale of capital investment, the regulation of resources and environment, and the ability of scientific and technological innovation. In 2018, the driving factors had different effects on land use efficiency of counties (cities) in different districts. ③ Based on the characteristics of land use efficiency of counties (cities) and their driving factors in 2018, this paper proposed land management and control policies for different districts and formulates differentiated land use optimization strategies based on the principle of "efficiency first".[Conclusion] The land use efficiency and its driving factors in Zhejiang Province have obvious temporal and spatial heterogeneity, and the ability of scientific and technological innovation is the primary driving factor at this stage.
