Research Of Gentle Hillside Resources Functional Suitability Evaluation Based On Spatial Analysis

China is a mountainous country, which has rich resources of mountain. However, due to therestriction of engineering technology factor which makes us take advantages of mountain resourceswith high costs, low benefit and low operability that lead to shortage of available land resources.Meanwhile, gentle hillside resources, with lower elevation, slower slope and easier exploittechniques, become a kind of important reserve land resources. Therefore, the exploitationof gentle hillside resources is a hot spot. This paper selects gentle hillside as the research object toanalyze its suitability and function regionalization. By this study, I hope it can provide thereference to optimize city function regionalization and gentle hillside resources utilizing.Based on relevant literature and field survey, this paper combined the theory of landevaluation research with mountain city development, economics and urban geography to discussthe theoretical foundation of the functional suitability evaluation. Moreover, with spatial analysismethods such as DEM analysis, TIN data analysis, vector data overlay analysis and raster datacomposite analysis, this paper took Liandu district as a research case to explore the quantity,distribution and structure of the gentle hillside resources effectively. Besides, we used fuzzymathematics and the comprehensive index that aimed at ecological agricultural function and eco-economic development function to construct the index evaluation system and evaluate. Aftercalculated the comprehensive evaluation score with grid composite analysis in GIS, we try todivide four suitable grades in form of visualization as follows: appropriate, suitable, lesssuitable and not appropriate. Finally, we divide the suitability evaluation results into eco-agricultural functional area, eco-economic development functional area and Oujiang Riverecological conservation functional area as the1th grade and22functional areas in the2ed grade often classes.In the thesis, combining gentle hillside concept with mountain, urban progressing experienceand theory, I expanding the ideas of gentle hillside exploitation; at the same time, I putthe function concept into the suitability evaluation so that make the results of the suitabilityevaluation and function regionalization more currently, which enrich the system of land evaluationtheory; furthermore, it is an innovation that combing the ecological concept with the traditional agriculture concept and the construction concept to choose the functional suitabilityevaluation target.
