区域可持续发展中的自然保护小区建设研究——以明溪县为例

摘要

According to the theory of regional sustainable development,the plant species diversity in different small nature reserves in Mingxi,Fujian,China was analyzed based on survey of nest quaqrats method.The results showed that Gleason species richness indices in the small nature reserves such as SR6,SR1,SR2,SR7,SR3,SR5,SR4 were 12.780,10.940,9.359,9.261,8.768,6.161,6.108 respectively.Due to their background being protected,the species diversities of different small nature reserves varied significantly and could not be treated equally without discrimination.14 plant species which were investigated in small nature reserves were not reported in the near big Junzifeng Nature Reserve of Fujian,which illuminated that small reserves were important complementary for biodiversity conservation by big nature reserve.Among human disturbance,protected area,altitude（324m to 880m）,cover rate,the human disturbance impacted the biodiversity significantly.In addition,small nature reserves acted as the pass way of species flow,cushion system of the ecosystem,service system of the efficient ecosystem in regional sustainable development.%本文从区域可持续发展观点出发,通过巢式样方法对明溪县不同类型自然保护小区的植物物种多样性进行比较分析。结果表明,6号、1号、2号、7号、3号、5号与4号小区的物种丰富度分别为12.780、10.940、9.359、9.261、8.768、6.161和6.108,由于保护背景的差异,不同自然保护小区在物种多样性上差异显著。明溪县自然保护小区内有14种植物在福建君子峰自然保护区未发现,说明自然保护小区的存在可进一步保护生物多样性。在人为干扰强度、保护小区面积、海拔高度、森林郁闭程度等因素中,人为干扰强度对自然保护小区的生物多样性有显著影响。在区域可持续发展中,自然保护小区可作为物种流的传布通道、生态系统的缓冲体系以及高效的生态系统服务体系而发挥作用。
