摘　　要：传统生态空间评价方法常常忽略土地利用变化所造成的生态碳汇变化,难以衡量生态空间对碳中和目标的影响和贡献。研究利用土地利用转移矩阵和景观水平指数等工具,建立了基于InVEST模型的城市生态空间系统评价方法,并以上海市为例进行了分析。研究发现,2000年到2020年上海市生态空间格局呈现破碎化发展,耕地面积占比从60%降至40%,生态空间总体碳汇量减少6.22%。从土地利用转化趋势来看,各地类稳定性由高到低排列依次为建设用地、水体和耕地、湿地、草地、林地。前述研究为碳中和导向下的生态空间规划和管控提供了参考基准和分析工具。Traditional ecological space evaluation methods often ignore the ecological carbon sink changes caused by land use changes,and it is difficult to explore the influence mechanism and measure the contribution of urban ecological space to carbon neutrality goals.Based on InVEST model,this study established a systematic evaluation method of urban ecological space by use of land use transfer matrix and landscape level index,taking Shanghai as a case.The study found that from 2000 to 2020,the ecological space of Shanghai has shown a fragmented development,with a decrease in the proportion of farmland area from 60%to 40%.The overall carbon sequestration in the ecological space decreased by 6.22%.On the stability of land use conversion,the land types in descending order are construction land,water bodies&farmland,wetland,grassland,and forest.The study provided a guideline for the ecological spatial planning and management towards carbon neutrality.
