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.
