| Abstract: | Through the case study of Dongshan Island,the concept of landscape ecological risk assessment is inquired into,and a set of assessment method is developed. Arming at drought,typhoon,pollution accident and soil erosion in Dongshan Island,the probability and distribution of each kind of risk sources are evaluated.By using remote sensing data,historic record,survey data and by means of geographical information system,regional ecological risk assessment is finished.On the basis of assessment result,the environmental risk management countermeasure of Dongshan Island is advanced. |
