    ENGINEERING CONSTRUCTION SUITABILLTY EVALUATION OF LOW-SLOPE HILLY REGION IN HILLY TOWN-TAKING PLANNED URBAN AREA IN YIBIN CITY AS AN EXAMPLE

    • Along with the rapidly economic development, the rapid expansion of the city, the construction land demand gradually increase. In hilly and mountainous city, flat land is small, the contradiction between people and land is particularly prominent. In order to scientifically and safely use low-slope hilly region, we must evaluate the engineering construction suitability of low-slope hilly region in hilly town. Taking plannedurban area in Yibin City asthe research area, we firstly establish the engineering construction suitabilityevaluation index system which is composed of 5 first grade evaluation factors and 18 second grade evaluation factors, calculate weight of evaluation factors based on APH.Then we evaluate engineering construction suitability of low-slope hilly region in research area with evaluation model of multi factor weighted index on arcgis 10.0. The results indicate that the low-slope hilly region is very wide in planned urban area in Yibin city, the low-slope hilly region accounts for 68.77% of total area. Suitable area accounts for 18.73% of total low-slope hilly region, relatively suitable area accounts for 42.21%,poorly suitable area accounts for 29.72%, and unsuitable area accounts for 9.34%.The engineering construction suitability of low-slope hilly regionin the research area is well. This paper can provide the scientific basis for use and plan of low-slope hilly region, city plan, optimize layout of land use, and perfect theengineering construction suitability evaluation theory system of low-slope hilly region.
