| 在可持续发展大背景下,深入探究中国生态环境质量与人类活动耦合机制并明确其影响因子,可为未来中国实现可持续发展目标提供一定的科学参考.运用趋势分析、耦合协调度、LMDI模型和最优参数地理探测器模型对中国生态环境质量与人类活动耦合机制进行探究和评价.结果发现:①在研究期间,中国耦合协调度、人类活动和生态环境质量均为增长趋势.人类活动和耦合协调度在空间上以胡焕庸线为界,呈现“东高西低”的分异规律.生态环境质量则表现出“南高北低”分异规律.②中国耦合协调类型转化的整体趋势为由低级向更高级的耦合协调类型转移.③基于最优参数地理探测器和LMDI模型分别发现,胡焕庸线以东绝大部分省区的耦合协调度其主导因子分别为社会经济因子和综合协调指数,该线以西绝大部分省区的耦合协调度主导因子分别为自然环境因子和耦合度.④评价人类活动变化对生态环境质量的影响,发现胡焕庸线以东主要为有利开发和有效保护类型,胡焕庸线以西主要为破坏开发和无效保护类型.胡焕庸线东西两侧地区应分别根据当地影响耦合协调度的先决条件以及人类活动和生态环境质量的相对关系,因地制宜选择优先发展地区,积极调整发展策略,走向生态环境质量与人类活动高级协调发展的可持续发展道路. |

| In the context of sustainable development, it is important to thoroughly investigate the coupling mechanism between China's eco-environmental quality and human activities, as well as identify the influencing factors, in order to provide scientific references for achieving sustainable development goals in China. This study applied trend analysis, coupling coordination degree, LMDI, and optimal parameter geographic detector models to explore and evaluate the coupling mechanism between China's eco-environmental quality and human activities. The findings of the study were as follows:① During the research period, there was a growth trend in China's coupling coordination degree, human activities, and eco-environmental quality. Human activities and coupling coordination degree exhibited a spatial differentiation pattern with the Hu Line as the boundary, showing an "east high, west low" distribution. The eco-environmental quality demonstrated a "south high, north low" differentiation pattern. ② The overall trend of China's coupling coordination type transformation was shifting from lower-level to higher-level coordination types. ③ Based on the geographic detector and LMDI models, the dominant factors influencing the coupling coordination degree in most provinces east of the Hu Line were social and economic factors, as well as the comprehensive coordination index. In contrast, the dominant factors in most provinces west of the Hu Line were natural environmental factors and coupling degree. ④ The evaluation of the impact of changes in human activities on eco-environmental quality revealed that the regions east of the Hu Line were mainly characterized by favorable development and effective protection, whereas the regions west of the line were mainly characterized by destructive development and ineffective protection. It is suggested that the regions on both sides of the Hu Line should prioritize development based on local prerequisites influencing the coupling coordination degree and the relative relationship between human activities and eco-environmental quality. It is crucial to actively adjust development strategies and pursue a sustainable development path towards the high-level coordination between eco-environmental quality and human activities. |
