摘要
通过构建人地关系耦合协调演化模型,对比分析了秦巴山区不同地形区人地关系的时空演化特征,探讨了人地关系演化过程中的驱动因素与作用机制。结果表明:地形差异导致的空间不均衡使得2000年以来秦巴山区人地协调发展状态并不理想,直到2010年以后在多重效应影响下,人地关系才出现向好发展趋势;低山平原区人地协调程度总体平稳主要由于较好的交通、建设条件和强经济发展带动了区域的高质量发展;中高山区人地协调程度下降跟其较差的建设条件和粗放的产业经济发展有关,使其城镇化进程和脱贫速度赶不上生态环境改善的速度。山区人地关系的协调状态与其资源利用效率和社会经济发展高质量水平密切相关,应通过优化内部功能和结构改善其地区资源低效配置问题。
In this study,we examined the constructed coupling and coordinated evolution model of the man-land relationship,compared and analyzed the temporal and spatial characteristics of its evolution in different terrain types in the Qinba Mountain area,and discussed the driving factors and mechanisms in the process of man-land relationship evolution.The results showed that:(1)the spatial imbalance caused by topographic differences resulted in an unsatisfactory coordinated development of the man–land relationship in the Qinba Mountains area since 2000,and a good development trend was only observed in 2010 under the influence of multiple effects.(2)The overall stability of man-land coordination in low mountain plain areas is mainly due to better transportation,construction conditions,and strong economic development,which sustained the high-quality development of the region.In contrast,the decline of man-land coordination in low mountain plain areas is mainly due to poor construction conditions and extensive industrial economic development,making it difficult for the urbanization process and poverty alleviation to keep pace with the speed of ecological environment improvement.(3)The coordination of the man-land relationship in mountainous areas is closely related to resource utilization efficiency and high-quality social and economic development.Therefore,the inefficient allocation of regional resources should be addressed by optimizing internal functions and structures.
