The Development Strategy Research Of Small-town In Karst Area Based On Multiple-factor Assessment

Due to the special geology and land-form, small-town development in Karst area has been restricted for a long time. This passage started with micro-data, discussed the environmental characters of Karst area, and then screened out the factors which influence the small-town development by corresponding to its character condition. According to factor assessment model, this passage analyzed each index factor's influence and importance to the process of the small-town development, and made pointed references to the entirety and hierarchical classification optimizing strategy of small-town development in Karst area via all varieties of influence's directing range, positive and negative effect, impact degree and analysis of aging retention. Thus, to help small-town development in this area to be a more scientific, controlled, effective and sustainable process, and positively promote specialized, differential, and connotative development of the small-town in this area at the same time.This passage is divided into three parts —— the construction of indicator system, the assessment of empirical analysis, the research of optimizing strategy.In the part of the construction of indicator system, established on natural environment andsocial economy development's general conditions in Karst area, by analyzing generalcharacters of its natural ecological sensitivity, urban construction limitation, social economyundeveloped and ethnic culture diversity, this passage typically screened out 38 impactfactors of influencing the small-town development in Karst area on four aspects of naturalecology, urban construction, ethnic culture and social economy, and hierarchically builtpotential assessment indicator system of small-town development according to criterionlayer, sub-criterion layer and factor layer.In the part of the assessment of empirical analysis, on the case of Anshun City, Guizhou Province, this passage went on an evaluation analysis of small-town development potentiality by the means of AHP and PCA respectively and divided included typical smalltown as Level ? development potentiality small-town, Level ? development potentiality small-town and Level ? development potentiality small-town on the basis of assessment results, thus teased the rank distribution characters and special distribution characters of small-town development potentiality through the conditions of synthesis score and criterion layer score.In the part of the research of optimizing strategy, firstly, from the point of classification according to the three-level division of assessment result, this passage discussed all levels of small-town's development conditions, development goals and possible methods, and then back-step to verify and assess the result referring to sample small-town's practical data of investigation. In addition, this passage made pointed references to goals and methods optimizing strategy of small-town development. Secondly, from the point of entirety, this passage concentrated on development conditions and regional small-town development typical issues in Karst area closely, and put forward “Optimize urban structure system and promote regional differentiation and disequilibrium harmonious development”, ”Clear the relationship of industrial division and lead tertiary industry to orientation harmonious development ”, ”Improve transportation network, connect and drive basic villages integrative development”, ”Stress on the connotation of ecological red line and propose social economy and space environment to a binding and fining development way”, ”Highlight landscape gene value and promote urban environment specialized and connotation development” these five development optimizing strategies.This passage started from the instant background and general problems of small-town development in Karst area, while built up an assessment model of screening out impact factors based on environmental characters and subject analysis combined with objective analysis. Its significance is mainly to go on a more intuitive and scientific way to evaluate development ability and constraint condition of small-town in Karst area, and to formulate a pointed optimizing strategy aimed to small-town unit and regional development, finally, to lead small-town to go on a scientific, healthy, coordinate and sustainable way.
