Gentle hillside area usually refers to the areas under 300 m in altitude and locating at the hilly area with terrain slope of 5°-15°. To some extent, utilization and development of gentle hillside area can contribute to relieve the problem of regional land resource supply tension, which is a real existent fact in most of regions, and may help achieve good social benefit. Most of the existing researches on the evaluation of suitability of gentle hillside area inside and outside China have adopted static way in general terms, which might not reflect the changing of land use condition completely, because of their lack of consideration of land use changing trending and applying those models with changeless weight to calculate for evaluation research, and have seemed to get comparatively unbelievable results. The purpose of this paper was to provide theoretical basis and methods for scientifically constructing suitabilityevaluation index system of industry transfer in gentle hillside area, which contributed to utilize land resource in gentle hillside area to develop industry efficiently and reasonably. This paper adopted GIS (geographical information system) and empirical studies, and literature research and questionnaire survey were synthetically applied. The paper constructed the evaluation index system with 3 evaluating target including basic conditions, traffic conditions and continuous conditions of industry development. And 13 indicators were selected, which included proportion of industrial output, proportion of existing industrial park, per-capita freight volume, road network density of ordinary highway, quantity of public transit hub, quantity of freight station, quantity of highway interchanges, distance to the nearest freight wharf, distance to the nearest freight station, distance to the nearest airport, average annual growth rate of fixed assets investment, proportion of professional personnel and land consumption per 108 yuan GDP (gross domestic product). The data statistical analysis was carried out and the processing method was built based on confidence interval, the index weight was corrected with dynamic weight, and the suitability of industry transfer in gentle hillside area of Liangjiang New Area in Chongqing was calculated and analyzed with the weighted average model. Then, the changing situations of suitability evaluating of industry transfer of each evaluating unit before and after the correction of evaluation index weight were contrasted and analyzed, and the grade map was compiled. The result is trustworthy, and has high reliability and viable method, which might enrich the theory and method for suitability evaluation of land resource in gentle hillside area and provide the reference and practical support for development, utilization and management of land resource in gentle hillside area. In theory, this evaluation research should be classified as macroscopic evaluation, however, evaluation research of micro block unit should be further verified in the future for enhancing the scientific nature and rationalization. At the same time, the evaluation of ecological and economical risk should also be considered in this type of research.
