Dynamic of forest landscape pattern based on RS and GIS in Meicheng forest-farm

LandsatETM+ RS images of Meicheng forest-farm of Dongzhi county in Anhui Province in 1999 and 2006 were used as the main data sources, along with the data of forest management inventory, etc. Based on the remote sensing images processed, the forest landscapes were classified and mapped by the method of unsupervised classification. The forest landscape indices were calculated in FRAGSTATS. The dynamic changes of forest landscape were analyzed based on the forest landscape indices. The results shows: the total patch number decreased obviously, and the fragmentation of the forest landscape declined gradually, but pine forest and fir forest were still main parts of landscape patterns. The shape of forest landscape patches were rule and simple. The connection degree of different landscape types was very high. The diversity and evenness of forest landscapes increased little from 1999 to 2006.
