【摘要】：科学开展土地整治空间格局及其影响因素分析,是明确区域土地整治方向、分解整治规划指标和实施差别化整治策略的重要依据。该文以"压力-状态-响应"的概念框架作为理论依据,构建土地整治的PSR(pressure-state-response)评价指标体系,综合熵权TOPSIS模型、组合矩阵模型和障碍度模型等系统算法,划分土地整治空间格局,探讨不同区域土地整治的障碍因素及调控策略,基本形成了土地整治空间区划的理论与方法体系。实证分析表明:1)山东省139个县(市、区)中土地整治压力分值高于全省均值的比例为69.04%,状态和响应分值低于全省均值的比例分别为50.68%和70.51%,表明山东省整体土地整治的压力较高、状态水平中等和响应程度偏低。2)山东省"3+6"的土地整治空间格局中,3大主区包含县(市、区)的数量比例相对均衡,分别是37.41%、28.78%和33.81%,空间分布也比较集中;而对应6种整治类型的县(市、区)数量比例差异较大,在7.91%~20.86%之间,且空间异质性显著;说明土地整治空间区划过程中需要将"自上而下"的区域综合评价与"自下而上"的区域差异识别统筹兼顾。3)山东省土地整治障碍因子作用频次具有区域相似性和差异性的双重特征,土地整治潜力和经济支撑能力的薄弱是约束土地整治响应的主要阻力,建议引入市场机制,探讨因地制宜的多元治理模式。本研究是对"自下而上"土地整治空间格局划分方法的有效补充,藉此完善土地整治区划的理论与方法,并为"十三五"土地整治规划提供有益参考。
[Abstract]:Scientific analysis of spatial pattern and influencing factors of land regulation is an important basis for defining the direction of regional land regulation, decomposing the planning index and implementing differential regulation strategy. Based on the concept frame of "pressure-state-response", this paper constructs the PSR (pressure-state-response) evaluation index system of land renovation, synthesizes entropy weight TOPSIS model, combined matrix model and obstacle degree model, and divides the spatial pattern of land renovation. This paper discusses the obstacle factors and control strategies of land regulation in different regions, and basically forms the theory and method system of land regulation spatial regionalization. Empirical analysis shows that the proportion of land regulation pressure score in 139 counties (cities and districts) in Shandong Province is 69.04 higher than the average value of the province, and the proportion of the state and response score lower than the provincial average is 50.68% and 70.51%, respectively, indicating that the overall land regulation pressure in Shandong Province is high. In the spatial pattern of "36" land regulation in Shandong Province, the number of counties (cities and districts) is relatively balanced, which is 37.41% and 33.81%, respectively, and the spatial distribution is relatively concentrated. The proportion of counties (cities and districts) corresponding to 6 types of regulation was different, which was between 7.91% and 20.86%, and the spatial heterogeneity was significant. It shows that the "top-down" regional comprehensive evaluation and "bottom-up" regional difference identification should be taken into account in the process of land regulation spatial regionalization.) the frequency of land regulation obstacle factor in Shandong Province has regional similarity. And the dual characteristics of diversity, The weakness of land regulation potential and economic support ability is the main resistance to restrain the response of land regulation. It is suggested that the market mechanism be introduced and the multivariate governance model according to local conditions be discussed. This study is an effective supplement to the "bottom-up" land regulation spatial pattern division method, thus perfecting the theory and method of land regulation zoning, and providing a useful reference for the "13th Five-Year Plan" land regulation planning.
