Construction of a Landscape Ecological Network for a Large-Scale Energy and Chemical Industrial Base: A Case Study of Ningdong, China

A large-scale energy and chemical industry base is an important step in the promotion of integrated coordinated development coal its downstream coal-based industry. number industrial bases have been built Yellow River Basin that rely on rich resources. However, ecological environment fragile this region. Once eco-environment destroyed, wildlife would lose habitat. Therefore, area has attracted wide attention regarding while also protecting environment. An network could improve landscape connectivity provide ideas for restoration. This study took Ningdong Energy Chemical Industrial Base as a case study. Morphological spatial pattern analysis was applied to extract core patches. The patches evaluated, then source were recognized. minimum cumulative resistance model, hydrologic circuit theory used simulate network. Then, corridors nodes classified. results follows: (1) vegetation fractional coverage recently significantly improved. 22,433.30 ha. In addition, 18 extracted patches, with total 9455.88 ha; (2) Fifty-eight potential simulated. it difficult form natural corridor because area’s great resistance. Moreover, poor between east west; (3) 52 simulated high-importance concentrated western grassland Gobi Desert. indicated restoration be conducive area. Furthermore, five high importance but low should given priority later construction. summary, optimizing achieve suggested severe eco-environmental challenges urgently need more appropriate policy guidance large bases. Thus, construction combined, effectiveness effectively achieved, cost reduced.
