地理信息系统支持下的区域土地资源适宜性评价

在可持续发展理论的指导下，以山西省朔州市平鲁区为研究对象，通过对平鲁区彩红外航片的室内判读和野外实地调绘，获取了该区的土地资源数据；以ＧＩＳ为工具，建立了该区的土地资源管理信息系统。在该系统的基础上，应用综合指数法，以地块为评价的基础单位，进行了平鲁区土地资源适宜性评价，该文确定了划分各评价等级界限值及其计算方法，得出的评价结果符合实际，客观可行。

Regional Land Resources Suitability Assessment Based on Geographical Information System

Based on the theory of sustainable development,taking Pinglu(Shuozhou city,Shanxi province)as the study area, using Geographical Information System,the land resources,management information system(LRMIS)was developed(the land resources data of the study area were obtained by aerial-photograph).And based on LRMIS, the plot was taken as a unit,the complex-index method was used in land suitability assessment. The critical values of the assessment classification and the calculating method were given in the paper. Comparing with the actual data,that the result was satisfied.
