The authors study landscape pattern and ecological value of shelter forests in Dongshan Island by landscape ecological theory and quantitative valuation method of forest environmental value.Some landscape indicators including patch density,edge density,fractal dimension of patches,landscape diversity,landscape dominance and Shannon's evenness index were selected to analyze the spatial distribution and spatial pattern feature of shelter forest landscape types in Dongshan Island.The service function of the forest ecosystem was evaluated using market valuation method etc.from the viewpoints of small scale shelter forest ecosystem and important ecological service function.Results showed that landscape pattern of shelter forests in Dongshan Island was greatly affected by human activities,and that averaged value of service function of shelter forests in Dongshan Island adds up to 39.45×106-92.55×106 yuan in terms of CO2 fixation,O2 release,wind protection and sand stabilization.
