Abstract:

To explore diversity maintaining mechanism and restoration after disturbance of the plantation, we established a 1-ha dynamic rubber plantation plot and managed it in a close to nature way according to the core theory of close to nature forest. Based on field survey data, plant species composition and distribution in the rubber plantation was analyzed. A total of 183 species belonging to 155 genera and 69 families were recorded in the plot. In the area of ??4,000 m2, 3,000 m2 and 2,000 m2, the plot contains about 90% of species, genus and family respectively. Logistic model fitted species-area is very good with R2 0.997, which indicates that 1-ha plot is large enough for monitoring of species diversity of rubber plantation. The distribution pattern of abundance and richness in the plot are very different from those constructed from random placement model, which indicates that the unevenness distribution of abundance and richness are not caused by the random distribution. The species-abundance distribution of the plot could not be well fitted by using the lognormal model and log serial model. In comparison, the lognormal model fits it better than log serial model.

Key words: close to natural management, species diversity, species-area curve, speices-abundance distribution
