基于中小湖泊水网体系的景观生态网络构建研究OA

With the continuous expansion of urban construction land and cultivated land,the ecological sources have been damaged,leading to a series of problems,such as habitat fragmentation,weakened water network connectivity,and a sharp decline in biodiversity.The construction of landscape ecological networks is an effective approach to address these issues.The pilot area of the Yangtze River Delta Integration Demonstration Zone(hereafter referred to as the Pilot Area),as a key region in the national development strategy,faces prominent ecological conflicts during the rapid regional economic development.Based on the MSPA-MCR model,the paper extracts and selects the ecological corridors,and ultimately builds a landscape ecological network.The research results show that the overall landscape habitat quality in the Pilot Area is relatively high.The construction of 15 major ecological corridors and 19 general ecological corridors takes Dianshan Lake,Yuandang Lake,and Sanbaidang Lake as the core,and connects other small and medium-sized lakes and other ecological lands,among which,the material and information exchange between Dianshan Lake and Yuandang Lake is the most frequent.
