Abstract

Abstract:

Statistics analysis showed the general pattern of forest type diversity in studied area: most villages had forest type of two predominant tree species;the number of forest type in mosaic pattern increased from the northern to the southern. A maximal covering model on forest type diversity and reserve selection had been built .The model was solved by greedy algorithm,and five villages had been selected for the maximal covering pattern of forest type diversity and they were suitable for reserve sites. The forest type diversity was probably not only formed by nature, human influence could not be completely excluded in the studied area.

Key words: Forest type, Biodiversity, Ecosystem, Maximal covering model, Greedy algorithm
