Evaluation and Construction of Regional Ecological Network Based on Multi-Objective Optimization: A Perspective of Mountains–Rivers–Forests–Farmlands–Lakes–Grasslands Life Community Concept in China

Landscape degradation and habitat fragmentation are some of the most urgent environmental problems associated with human development regional integrated planning. Regional ecological network planning involves connecting high-quality habitats reducing negative impact landscape on remaining natural patches through structural functional connectivity. The concept “mountains–rivers–forests–farmlands–lakes–grasslands life community”, as a system to solve whole problem in China, associates all factors relations systematic pattern, emphasizing systematicness integrality environment protection. This study, based progress study community” network, clarifies intrinsic connection systemic relationship between humans resources, it importance multi-objective construction for resources region. Taking Taishan area subject, approach “risk assessment–source identification–corridor extraction–node selection” was constructed from three objectives—ecological structure, process integrity service efficiency—based morphological spatial pattern analysis, minimum cumulative resistance model, gravity model other modeling methods. findings this can provide evidence clarification China.
