摘　　要：完善的交通基础设施网络是形成高度同城化和高度一体化城市群的前提和基础,科学探测城市群地区交通通达度对生态系统健康状况的影响机理对城市群地区生态系统保护以及区域可持续发展具有重要实践意义和价值。基于多源数据分别测度了1995—2015年长江中游城市群交通通达度以及生态系统健康水平,并借助双变量空间自相关与空间回归模型从全局和局部的角度揭示了交通通达度对生态系统健康的影响机理。研究结果显示:(1)研究期间长江中游城市群生态系统健康状况总体呈现降低态势,山区生态系统健康水平显著高于平原地区;(2)双变量空间自相关分析结果显示交通通达度和生态系统健康水平之间存在显著的空间依赖性,二者之间主要的关系类型包括低交通通达度水平-低生态系统健康水平、高交通通达度水平-低生态系统健康水平和低交通通达度水平-高生态系统健康水平三种类型;(3)空间回归结果显示交通通达度的增加会导致生态系统健康状况的恶化,而且交通通达度对生态系统健康的影响具有显著的空间异质性。研究发现可以为长江中游城市群地区生态系统健康保护宏观调控政策制定以及差异化管控政策制定提供科学依据。The gradual improvement of traffic network in urban agglomeration plays an important role in the construction of national land development environment, construction of national land development structure, and optimization of functional space system. At the same time, it also causes serious disturbance to the structure and function of ecosystem and the health status of ecosystem, and seriously threatens the sustainable development of urban agglomeration. How to promote the high-quality development of urban agglomerations and alleviate the disturbance and damage of urban agglomerations to ecosystem health has become an urgent problem to be answered and solved in the current development process of urban agglomerations. To scientifically reveal the spatial relationship between traffic accessibility and ecosystem health in urban agglomerations, and to clarify the impact mechanism of traffic accessibility on ecosystem health is an effective way to solve this issue. Based on multi-source data, this study measured the traffic accessibility and ecosystem health level in the middle reaches of the Yangtze River Urban Agglomerations(MRYRUA) from 1995 to 2015, and estimated the influence mechanism of traffic accessibility on ecosystem health with bivariate spatial autocorrelation and an integrated spatial regression models from the global and local perspectives. The results showed that:(1) the overall ecosystem health in the MRYRUA exhibited a decreasing trend, and the ecosystem health level in the mountainous areas were significantly higher than those of the plain areas during the study period.(2) The bivariate spatial autocorrelation results showed that there was a significantly spatial dependence between traffic accessibility and ecosystem health. The spatial relationships between them mainly included low traffic accessibility-low ecosystem health level, high traffic accessibility-low ecosystem health level, and low traffic accessibility-high ecosystem health level.(3) The spatial regression results showed that traffic acc
