摘　　要：江苏省沿江地区是整个长江经济带中生态承载压力最大、生态保护与经济活动矛盾最突出、生态修复形势最紧迫的区域,开展江苏省沿江地区生态空间格局优化和生态修复对策研究,对于推动长江经济带生态文明建设与高质量发展具有重要现实意义。文章以江苏沿江10千米范围涉及的区县为研究对象,分析了该区域的生态空间和特征,以及生态空间保护修复面临的主要问题;提出通过生态服务价值重要性评估和生态敏感性评价,选取生态源地,运用最小累积阻力模型识别生态廊道,构建江苏沿江地区生态空间格局,围绕生态节点、生态廊道等开展生态空间格局优化,并运用景观连接度指数对优化前后的生态空间加以评价;在此基础上,从规划引领、格局优化、监测预警、保障机制等方面提出政策建议。The area along the Yangtze River in Jiangsu Province is the area with the greatest ecological bearing pressure,the most prominent contradiction between ecological protection and economic activities and the most urgent situation of ecological restoration in the whole Yangtze River economic belt.The research on the optimization of ecological spatial pattern and ecological restoration countermeasures in the area along the Yangtze River in Jiangsu Province is of great practical significance for promoting the construction of ecological civilization and high-quality development of the Yangtze River economic belt.Taking the districts and counties 10 kilometers along the Yangtze River in Jiangsu Province as the research,this paper analyzes the ecological space and characteristics of this area,as well as the main problems faced by the protection and restoration of ecological space;It is proposed to select the ecological source through the evaluation of the importance of ecological service value and ecological sensitivity,identify the ecological corridor by using the minimum cumulative resistance model,construct the ecological spatial pattern along the river in Jiangsu,optimize the ecological spatial pattern around the ecological nodes and ecological corridors,and evaluate the ecological space before and after optimization by using the landscape connectivity index;On this basis,policy suggestions are put forward from the aspects of planning guidance,pattern optimization,monitoring and early warning,guarantee mechanism and so on.
