武夷山黑麂生境适宜性评价

Evaluation of Habitat Suitability of Muntiacus crinifrons in the Wuyi Mountain

道路网络建设促进区域社会经济发展的同时也阻隔了野生动物的通行和交流,影响或破坏了生境。武夷山是地球上同纬度生物多样性最丰富的地区之一,栖息着许多珍稀野生动物。本研究以黑麂(Muntiacus crinifrons)为目标物种,对其生境适宜性进行了评价,并借助水文分析模拟动物潜在的运动轨迹。结果表明:黑麂最适宜生境面积占研究区总面积的16.53%,其他依次是一般适宜、较适宜、较不适宜和不适宜,占比分别是29.63%、22.69%、20.77%和10.38%。最适宜生境主要集中于武夷山国家级自然保护区的核心区,通过模拟得到的动物足迹与道路网络叠加,发现5处动物足迹受到道路的阻隔,其中与高速公路相交1处、与省道相交1处、与县道相交1处和与乡道相交2处。研究结果可为制订生境保护和修复政策提供参考,对野生动物保护具有重要意义。

Road network construction promotes regional socio-economic development,while inevitably it blocks the passage and communication between wildlife in the area from both sides of the roads,affecting or even destroying the habitats of wildlife.The Wuyi Mountain,one of the most biodiverse areas among the same latitude on the earth,is the home to many rare wild animal species,the artiodactyls in particular.This thesis took Muntiacus crinifrons as an example,to evaluate its habitat suitability,simulate the potential movement routines of the artiodactyls,and analyze the impacts of the road network on their habitat suitability.The results showed that the most suitable habitats for the artiodactyls were mainly concentrated in the core area of the Wuyi Mountain National Nature Reserve.Through simulating their footprints and the road network mentioned above,the impacts of road network on the habitats of the wild animals were accurately evaluated.We found 5 areas of wildlife habitats blocked by roads,including 1 intersection with the expressway,1 intersection with the provincial highway,1 intersection with the county road and 2 intersections with the rural road.The results provide scientific references towards wild animal protection and coming up with proper measures towards habitats'reservation and restoration.
