摘要

[目的

]

在国土空间规划背景下，构建合理的生态安全格局，为优化县域国土开发格局以及推进城市生态文明建设提供参考。[方法

]

参考双评价工作指南，从生态系统服务功能重要性与生态脆弱性角度对江西省瑞金市进行生态保护重要性评价，从而识别生态源地，结合瑞金市的实际情况选取合适阻力因子建立阻力面，利用最小累计阻力模型识别生态廊道，综合构建瑞金市生态安全格局。[结果

]

通过生态保护重要性评价识别的瑞金市生态源地面积为1 562.296 km

，占研究区面积的64%，通过乡行政界限修正提取出13个生态结点，以此为基础识别廊道21条，廊道总长度共计875.94 km，综合构建呈“一网三区”的瑞金市生态安全格局。[结论

]

通过生态保护重要性评价构建的瑞金市生态安全格局满足政策规划需求，可为瑞金市及类似城市国土开发格局优化与生态文明建设提供可行的参考方法。

Abstract

[Objective] In the context of territorial and spatial planning

a reasonable ecological security pattern was constructed to provide references for optimizing the pattern of county territorial development and promoting the construction of urban ecological civilization.[Methods] With reference to the double evaluation work guide

the importance of ecological protection of Ruijin City

Jiangxi Province

was evaluated from the perspective of the importance of ecosystem service functions and ecological vulnerability to identify the ecological source. Based on the actual situation of Ruijin City

appropriate resistance factors were selected to establish resistance by using the least cumulative resistance model to identify ecological corridors and comprehensively construct the ecological security pattern of Ruijin City.[Results] The ecological source area of Ruijin City identified through the evaluation of the importance of ecological protection was 1 562.296 km2

accounting for 64% of the study area. The administrative boundary correction extracted 13 ecological nodes

and 21 corridors were identified on this basis. The total length of the corridors was 875.94 km

and the ecological security pattern of Ruijin City

which was like "three nets and one district"

was comprehensively constructed.[Conclusion] The ecological security pattern of Ruijin City constructed based on the evaluation of the importance of ecological protection

conforms to the policy tendency. It provides a feasible reference method for the optimization of the land development pattern and the construction of ecological civilization in Ruijin City and similar cities.
