摘要:
选用最小斑块面积、分维度指数、多样性指数等对广西弄岗国家级自然保护区的土地利用类型结构进行分析,结果表明,(1)5种土地利用类型面积排序为:有林地>灌木林地>辅助生产用地>非林地>未成林地;(2)在5种土地利用类型中,最小斑块面积0.37 hm2,为灌木林地,呈孤岛状分布于有林地中,表明了热带石山季雨林面积的扩张和整个自然生境的动态演替;(3)保护区多样性指数为0.530,优势度指数为1.080,均匀度指数为0.329;保护区内有林地占较大的优势,有利于北热带石灰岩季节性雨林生态系统的保护;(4)保护区分散度为1.26%,以自然景观为主。整个保护区景观格局合理,是典型的保护区景观结构,能够有效保证当地生态系统的稳定性。
Abstract:
Indicators like the minimum patch area, fractal dimension index, diversity index, etc. were selected to analyze structure of land-use types of Guangxi Nonggang National Nature Reserve. The result demonstrated that area of the five land use types was ordered by forest land>shrub land>auxiliary production land>non-forest land> young forest land. The minimum patch area among different land use types was shrub land, only 0.37ha in forest land, indicating extension of tropic monsoon forest and dynamic succession of natural habitat. The diversity, dominance and evenness index of the reserve was 0.530, 1.080 and 0.329. Forest land dominated in the reserve, helping to protect Northern tropical limestone seasonal rain forests ecosystem. The dispersion degree of the reserve was 1.26%, majored by natural landscape. The study resulted that landscape pattern of the reserve was a typical structure of reserve and could effectively maintain the stability of the local ecological system.
