A new stage in promoting the construction of the Silk Road Economic Belt Core Area, and Xinjiang has been transformed from a relatively closed inland area into an open border. In order to promote the high-quality development of Southern Xinjiang and solve the imbalance contradiction between the development of the Northern Xinjiang and Southern Xinjiang, taking the four districts in Southern Xinjiang as the study area, constructing a high-quality development ecological niche index system of three levels, namely economic, social and ecological, adopting the entropy method to assign weights to the evaluation indexes, and measuring the ecological niche width and the degree of ecological niche overlap of this region in the period from 2011 to 2020. The results show that: Firstly, tourism has the greatest impact on the ecological niche of economic development in state N, with a weighting of 14.18%; Secondly, the ecological status width of economic development in state N demonstrates a structural characteristic of "low level and low gap". The average value of ecological niche width is at class III, indicating a low development status and weak regional influence; Thirdly, the ecological niche overlap of state N is significantly influenced by spatial factors. Regions Z and S are closer together, resulting in higher competition for resource utilization and an average ecological niche overlap at class II. The other two regions are at class III. According to the theory of ecological niche expansion and separation, a specialization separation strategy should be adopted for areas with "low width and high overlap", and a strengthening expansion strategy should be adopted for areas with "low width and low overlap", to optimize the structure of ecological niches and promote high-quality development of the region.
推动丝绸之路经济带核心区建设迈上新台阶，新疆由相对封闭的内陆地区变成对外开放的前沿。为了促进南疆高质量发展，解决北疆和南疆发展不平衡的矛盾，以南疆四地州为研究区，构建了经济、社会和生态三个层次的高质量发展生态位适宜度指数体系，采用熵权法对评价指标进行权重赋值，并测算了该区域 2011-2020 年的生态位宽度和生态位重叠度。结果表明：首先，旅游业对 N 州经济发展生态位的影响最大，权重为 14.18%；其次，N 州经济发展生态位宽度呈现“低水平、低差距”的结构性特征，生态位宽度平均值处于三级，表明发展水平较低，区域影响力较弱；再次，N 州的生态位重叠受到空间因素的显著影响，Z 区和 S 区相互接近，导致资源利用的竞争更加激烈，平均生态位重叠处于二级，其他两个区域处于三级。根据生态位扩展和分离理论，对于“低宽度、高重叠”的区域应采取专业化分离策略，对于“低宽度、低重叠”的区域应采取强化扩展策略，优化生态位结构，促进区域高质量发展。
