Abstract: By the methods of systematic ecology,and that of Simpson's biodiversity indices in particular,this paper quantitatively analyzed the ecological effects of ten years land use changes in a small town with rapid rural urbanization of Shaoxing County,Zhejiang Province,aimed to provide a scientific basis for healthy development of towns and small cities in China.The results showed that owing to the changes of land use functions,the biodiversity of green plants and soil microorganisms was obviously decreased,and the local climate conditions deteriorated,which was represented by the increase of annual mean air temperature and the decrease of annual mean relative humidity in this town.It was suggested that the long-term ecological changes in biodiversity should be considered in land use with rural urbanization.
