桂东珍稀野生动物保护的安全格局分析

Analysis on the Safety Pattern of Rare Wild Animal Protection in Guidong

  • 摘要: 以湖南省桂东县为例,划定珍稀野生动物保护区域;提取物种栖息地作为生态源地,利用最小累积阻力模型建立阻力面,识别物种迁移廊道和战略节点;构建珍稀野生动物保护安全格局,并对野生动物的保护提出建议。结果表明:桂东县珍稀野生动物保护区域面积为819.52 km2,主要由林地和湿地组成;通过阻力面的构建,共识别战略点4个;生态廊道4条,廊道总长度为186.58 km;依据战略节点、生态廊道和珍稀野生动物保护区的分布,构建了“战略节点—生态廊道—珍稀野生动物区”点线面相结合的保护框架,可为野生动物保护规划提供参考。

     

    Abstract: Taking Guidong County of Hunan Province as an example, the rare wild animals protection area was first delimited. The species distribution area as ecological sources, and used in the Minimum Cumulative Resistance model to establish the resistance surface, then the species migration corridors and strategic points were identified. Finally, the security pattern of rare wild animals protection was constructed which can offer suggestions for rare wild animals protection. The results showed that the protection area of rare wild animals mainly composed of woodland and wetland, and the area is 819.52 km2. Four strategic points and four ecological corridors are identified by the construction of resistance surface, and the total length of corridors is 186.58 km. According to the distribution of strategic points, ecological corridors and rare wild animals reserve, a protective framework combining 'strategic points-ecological corridors-rare wild animals reserve' is constructed to provide scientific reference for wildlife conservation program.
