【摘要】 本文以合肥都市圈为例，运用景观格局指数分析、InVEST模型评估碳储量及双变量空间自相关和灰色关联分析其相关性，研究2000—2020年土地利用景观格局、碳储量时空变化特征及各景观指数与碳储存能力的关联度。研究表明：（1）2000—2020年，耕地面积减少占比为3.05%，空间转换以耕地—建设用地转化为主导；（2）景观格局变得更复杂，建设用地与草地破碎度提升，林地连接性增强，耕地最大斑块指数下降；（3）总碳储量下降253.21×10~5t，高值区主要分布在西南部低值区分散在各城市建成区；（4）土地利用强度与碳储量保持紧密联系，景观指数与总碳储量的相关性排列顺序为：聚集度>斑块密度>景观形状指数>最大斑块指数>景观分割指数>香农均匀指数>边缘密度>香农多样性>散布与并列指数。据此，合肥都市圈应强化农林业管理，严格管控建设用地转换，山地丘陵区实施景观形态复杂度分区优化，平原区重点增强斑块集聚度。更多还原

【Abstract】 Taking Hefei metropolitan area as an example,using landscape pattern index,In VEST model to evaluate carbon storage,bivariate spatial autocorrelation and gray correlation to study land use landscape pattern,carbon storage spatio-temporal change characteristics and each landscape from 2000 to 2020 Correlation between index and carbon storage capacity.Research shows thet(1) From 2000 to 2020,the proportion of cultivated land area was 3.05 %,and the spatial conversion was dominated by the conversion of cultivated land to construction land;(2) The landscape pattern is more complex,the fragmentation of construction land and grassland is increased,the connectivity of forest land is enhanced,and the maximum patch index of cultivated land is reduced;(3) The total carbon storage decreased by 253.21 ×10~5t,and the high value areas were mainly distributed in the southwest and the low value areas were scattered in the built-up areas of cities;(4) Land use intensity is closely related to carbon storage,and the correlation order between landscape index and total carbon storage is:aggregation degree> patch density> landscape shape index> maximum patch index> landscape partition index> Shannon uniformity index> edge density> Shannon diversity> walking and juxtaposition index.Therefore,Hefei metropolitan area should strengthen agricultural and forestry management,strictly control the conversion of construction land,implement zoning optimization of landscape form complexity in mountainous and hilly areas,and focus on strengthening patch agglomeration in plain areas.更多还原
