中文摘要:
      为优化合肥市绿色基础设施(GI)网络格局,基于供需关系量化了2022年合肥市GI的供给与需求,并结合电路理论构建与优化了GI的网络格局。结果表明,合肥市GI供给南北差距显著,南部GI供给斑块多,北部较为稀疏和分散;GI需求呈现中心高、外围低的圈层特征。合肥市GI供给源地共15个,总面积1 294.2 km2;GI需求源地5个,总面积567.1 km2。合肥市供给源地呈现“一核多点”的空间结构,北部没有供给源地;需求源地分布在市中心城区和下属县域中心范围内,绝大多数是建设用地。合肥市GI网络包含供给廊道26条,总长度431.3 km,服务廊道 16条,总长度185.5 km,重要生态夹点19个,障碍点16个。
英文摘要:
      In order to optimize the network pattern of green infrastructure (GI) in Hefei City, this study quantified the supply and demand of GI in 2022 from the perspective of supply and demand, and constructed and optimized the network pattern of GI by combining circuit theory. The results showed that there was a significant gap in GI supply between the northern and southern parts of Hefei City, with more GI supply patches in the south and more sparse and scattered in the north. GI demand exhibited a circle characteristic of high in the center and low in the periphery. There were 15 GI supply sources in Hefei, with a total area of 1 294.2 km2, and 5 GI demand sources, with a total area of 567.1 km2. The supply sources showed a spatial structure of of “one core with multiple points”, with no supply source areas in the north. Demand source areas were distributed within the central urban area and county-level administrative centers, most of which were construction land. The GI network of Hefei City consisted of 26 supply corridors with a total length of 431.3 km, 16 service corridors with a total length of 185.5 km, 19 important ecological pinch points and 16 obstacle points.
