Abstract

Abstract

Island is a relative independent ecosystem. Just because of its independence, once happening natural deserters, the landscape patterns of island ecosystem would change, which makes the landscape not be stable. Landscape stability shows fastness and resilience. So the resilience that island recovers to its original stable situation once it was destroyed is correlation with island risk degree. The more stable landscape is, the smaller risk degree is, and vice versa. The relation between landscape stability and landscape diversity, landscape fragile degree, landscape mosaic's spatial diversity and human disturbance degree is analyzed. The correlation of island landscape pattern with island risk degree is pointed. A risk assessment method of natural hazard for island based on landscapes patterns was presented. Based on landscape diversity index, landscape fragile index, landscape mosaic's spatial diversity index, and the proportion of manmade landscapes, a risk assessment model of natural disasters for islands is proposed. Daheishan Island, Beichangshan Island and Nanchangshan Island of Nanwu Island in China are chose for study areas, and the proposed risk assessment method in this paper is applied in the study areas. It shows that the assessment results using the proposed method were coincided with the traditional methods.
