Soil suitability evaluation aims to optimally allocate crop planting through measuring the coupling of designating crop to given land,and considers simultaneously soil physical features and current/future land use patterns.In this paper,data acquisition and analysis were based on physical and chemical properties of 70 soil samples from planting area of Shibing County.Using the GIS technology,soil suitability was evaluated by the testing index and method under complex geographical environment conditions to obtain soil suitability evaluation results and suitability map.%土壤适宜性评价是针对具体作物在特定地域种植的土壤适宜度所做出的定性、定量和定位的结论性评价,具有实践性、经验性、客观性及应用性的特点.本论文在采集、分析施秉县种植区70个土壤样品理化性质的基础上,基于GIS技术,采用检验指数和方法对复杂地理环境条件下的土壤适宜性评价进行研究,得出土壤适宜性评价结果以及适宜性评价图.
