摘　　要：通过构建开发强度与生态环境评价指标体系,系统分析2005—2016年东北限制开发区域开发强度与生态环境协调发展的时空格局特征与影响因素。结果表明:(1)土地开发强度增加和经济总量扩张的交互关系是造成东北限制开发区域开发强度综合水平提升的主要原因;同时由于生态环境状态增长的持久性不强,生态环境响应正逐渐成为改善区域生态环境综合水平的主要推动力。(2)东北限制开发区域开发强度综合水平呈现自南向北不断降低的特点,辽宁省明显高于吉林省与黑龙江省;区域生态环境综合水平呈现典型的南北空间分异特征,且生态环境水平相似地区集聚发展现象愈发明显。(3)东北限制开发区域开发强度与生态环境耦合协调度呈持续增长趋势,开发滞后性特征明显,勉强协调-开发滞后型(Ⅲ)、中度协调-开发滞后型(Ⅵ)是主要耦合协调发展类型。(4)城市化水平、经济发展水平以及政府调控水平是影响东北限制开发区域开发强度与生态环境耦合协调度的重要因素,而产业结构水平与外商投资水平没有通过显著性检验。On the basis of constructing development strength and eco-environment evaluation index system,this article analyzes the spatio-temporal pattern characteristics and the influencing factors of coupling coordination between development strength and eco-environment in the Restricted Development Zone Northeast China.The results show that: (1) The interaction between the increase of land development strength and the expansion of total economic output is the main reason for the improvement of development strength comprehensive level in the Restricted Development Zone of Northeast China;The persistence of eco-environment state is not strong,and the eco-environment response is gradually becoming the main driving force to improve the regional ecoenvironment comprehensive level. (2) The spatial pattern of the development strength comprehensive level in the Restricted Development Zone Northeast China has been decreasing from the south to the north, and Liaoning Province is obviously higher than Jilin Province and Heilongjiang Province;the spatial pattern of the regional eco-environment comprehensive level shows typical characteristics of the north area and south area, and the agglomeration phenomenon among the similar areas’ eco-environment level is obvious. (3) Coupling coordination degree between development strength and eco-environment increased continuously, and the development lagged is obvious;During the study period, the barely coordinated-development lagged(Ⅲ) and the moderately coordinated-development lagged(Ⅵ) are main types of coupling coordinated development. (4) The influencing factors of coupling coordination relationship between development strength and eco-environment in the Restricted Development Zone Northeast China include urbanization level, economic development and government regulation, while the function of industrial structure and foreign investment were not obvious.
