摘　　要：以江西省赣州市为研究区域,选取2000年、2010年和2020年为研究时间节点,在生态系统服务价值评价和电路理论的基础上,对赣州市最终的生态安全格局进行识别。结果表明,赣州市生态核心区共7780.32 km^(2),主要包括稳定的生态源地、生态系统服务价值较高的林地以及国家级森林公园和自然保护地等;生态缓冲区共5993.92 km^(2),主要是为了保护生态源地而构建的缓冲区,对生态源地具有一定的保护作用;水土保持区共499.90 km^(2),主要由研究区域内的河流和水库构成;重点修复区共1178.33 km^(2),主要包括生态夹点和生态障碍点区域;城镇建设区共2873.40 km^(2),由城镇用地和农村居民点等生态阻力高值所在区域构成。另外,针对生态脆弱地区提出了相应的生态修复建议。Taking Ganzhou City,Jiangxi Province as the study area,the years 2000,2010 and 2020 were selected as the study time points to identify the final ecological security pattern of Ganzhou City on the basis of ecosystem service value evaluation and circuit theory.The results showed that the ecological core area of Ganzhou City,totaling 7780.32 km^(2),mainly consisted of stable ecological source lands,forest lands with high ecosystem service values,and national forest parks and nature reserves;the ecological buffer area,totaling 5993.92 km^(2),was mainly a buffer zone constructed to protect ecological source lands,which had a certain protective effect on ecological source lands;the soil and water conservation zone,totaling 499.90 km^(2),mainly consisted of rivers and reservoirs in the study area;the key restoration area,totaling 1178.33 km^(2),mainly consisted of ecological pinch points and ecological barrier areas;and the urban construction area,totaling 2873.40 km^(2),mainly consisted of areas with high values of ecological resistance such as urban land and rural settlements.In addition,corresponding ecological restoration proposals were made for ecologically fragile areas.
