摘要:

快速工业化、城镇化和现代化使得乡村地域系统面临的压力愈加突出,对乡村人地关系及资源组合状况的研究,是面向乡村振兴战略,实现乡村地域协调与高质量发展的科学基础。基于2000—2018年黄土高原313个县级行政单元数据,在构建乡村“人水土”系统指标体系的基础上,采用熵权TOPSIS法、空间自相关模型、GWR模型等方法研究3个子系统的时空分异规律,识别系统间的协同关系及其主要类型,揭示系统协同演化驱动机制。结果表明:①黄土高原乡村人类活动强度指数和水资源指数空间分布格局具有一致性,与土地资源指数空间错位显著,3个子系统指数均以较低水平等级为主,县域间不平衡性突出,但有减弱趋势。②黄土高原乡村系统协同关系类型以双维度制约型为主,研究时段内该类型县域数量呈倒U型变化特征,综合协调型县区数量逐渐增多,说明乡村逐步向高水平协调方向发展。③系统协调发展受自然及社会经济要素形成的资源分布与组合、流动与分配、资源需求利用及人口流动转移四元驱动机制所影响,不同要素对系统权衡强度和协调状态的作用不同。本文对优化乡村地域水土资源配置,促进乡村“人水土”系统协调演进有一定的借鉴意义。

Abstract:

Rapid industrialization, urbanization, and modernization have posed increasing pressure on the rural regional system, and studying the relationship between human and land and the combination of resources in rural areas is the scientific basis for realizing regional coordination in rural areas and high-quality development for rural revitalization. Based on the basic data of 313 county-level administrative units on the Loess Plateau from 2000 to 2018 and constructing the rural human-water-land indicator system, this study adopted the entropy weight technique for order preference by similarity to ideal solution (TOPSIS) method, spatial autoregressive model, and geographically weighted regression (GWR) model to examine the spatial and temporal differentiation pattern of the human, water, and land subsystems, identifying the synergistic relationship between the three systems and their main types, and revealing the driving mechanism of system synergistic evolution. The results show that: (1) The spatial distribution pattern of the rural human activity intensity index and water resource index on the Loess Plateau is consistent, and the spatial dislocation of the land resource index is significant. The three subsystem indices are mainly at low levels and the imbalance between counties is prominent, but there is a weakening trend. (2) The type of rural cooperative relationship on the Loess Plateau is dominated by two-dimensional constraints, which showed an inverted U-shaped change characteristic during the study period. The number of comprehensive coordinated counties is increasing, indicating that the rural areas of the Loess Plateau are gradually developing towards a high level of coordination. (3) The coordinated development of the system is influenced by the four-element driving mechanism of resource distribution and combination, flow and distribution, resource demand and utilization, and population flow and transfer formed by various elements. Intensity and coordination of factors vary. This study has certain reference significance for optimizing the allocation of water and land resources in rural areas and promoting the coordinated evolution of the rural human-water-land system.
