基于InVEST-MCR模型的野生动物栖息地生态网络构建研究
Research on the Construction of Wildlife Habitat Ecological Networks Based on the InVEST-MCR Model
摘要
Abstract
Ecological networks play a significant role in the protection of wildlife habitats.Trachypithecus leucocephalus,an endemic species of Guangxi,is classified as a first-class nationally protected wildlife in China.Currently,its habitats are largely fragmented and isolated,posing a serious threat to the survival of the species.This paper selects Jiuchongshan,Nongban,and Buzun reserves in Fusui County as ecological source areas,establishes a technical framework of"source identification-network construction-corridor optimization".The InVEST model is employed to accurately identify the key ecological source areas within the region,and the MCR model is used to construct an ecological network for the Trachypithecus leucocephalus.The gravity model is applied to identify the critical ecological corridors,and the targeted suggestions and optimization strategies are proposed for the construction of the network.The results indicate that the study identifies two major source areas,30 ecological stepping stones,32 important corridors,and 41 secondary corridors.This study provides theoretical support and practical references for the conservation of rare and endangered species'habitats and the maintenance of regional ecological security.关键词
