There will be severe personnel and economic loss if natural disasterhits this area. This article takes the Aksu region with a background of multiple kinds ofdisaster as an example to build the evaluation index system for the vulnerability againstnatural disaster in order to start the vulnerability evaluation against natural disaster, whichwill create theoretical significance and practical value for the disaster prevention, disasterreduction, disaster relief and the sustainability for the city.The paper is based on how to improve the capability of Aksu for disaster resistancevia the establishment of evaluation index system and the research on the city’svulnerability. Based on the experience of the former research, this paper describes how tobuild the evaluation index system by selecting indexes from the aspects of the elements tocause the disaster, economy, population and the environmental facilities. After build thesystem, the paper then evaluate and study on the vulnerability of Aksu.The paper firstly illustrates the conception of natural disaster vulnerability which isfollowed by a research summary on development history, current status and existingproblems of natural disaster vulnerability domestically and abroad. The paper takes onecity and eight counties of Aksu province as research object to analyze hazard-formativeenvironment from geographic characteristics and social economic conditions and toanalyze its natural disasters characteristics through the collection of relevant data ofnatural disasters from1949-2010of Aksu area. Under the guidance of the establishedvulnerability evaluation concept, the article builds the evaluation system. Furthermore,this article applies the fuzzy comprehensive evaluation to assess the city’s vulnerability.The analysis indicates that Aksu city, Toksu county, Awat county are with the highest levelof vulnerability, Wensu county with moderate the level of vulnerability and Kuche county,Baicheng county, Uqturpan county, Keping county with the lowest level of vulnerability.In the meantime, this paper puts forward countermeasures and suggestions about how toprevent and fight the natural disaster and raises the resource orientation for the furtherresearch.
