%X Land use pattern is one of the important factors influencing regional ecosystem health. An assessment index system of "vigor-organization-resilience-service" was built to diagnose the regional ecosystem health of Zhoushan Island. Of which, the vigor index was represented by relative density of vegetation, and organization index was indicated by four indices of landscape pattern, including contagion, Shannon's diversity, Shannon's evennesss, and ineterfusion &juxtaposition. The administrative units of town, township or subdistrict were taken for evaluation. Based on remote sensing images and land-use-survey data, using GIS and RS techonologies, the spatial and temporal dynamics of ecosystem health of Zhoushan in 5 successive periods during 1970-2005 were assessed in terms of the comprehensive parameters evaluation modle. The results showed that the ecosystem health of Zhoushan Island declined in the past 35 years in general. It dropped by 18% and 8% in good and ordinary areas respectively, while increased by 26% in worse area. The main reasons causing the decrease of the ecosystem health of Zhoushan Island were urbanization, beach land reclamation and industrial development.
