农用土地定级信息系统的研究——以新疆库尔勒市为例

STUDIES ON THE INFORMATION SYSTEM OF CULTIVATEDLAND CLASSIFICATIONA CASE STUDY:KORLA CITY,XINJIANG UYGUR AUTONOMOUS REGION

分析了用计算机进行土地定级的方法，并结合新疆库尔勒市农用土地定级课题的成果，提出运用多元回归的方法确定因子权重，对该市农用土地定级信息系统的建立作了初步探讨，完成了该市的农用土地定级工作．

Based upon the research work in Korla city, Xinjiang Uygur Autonomous Region, the information system of cultivated land classification is established and discussed in this paper.The methods of land classification with computer are analysed and compared in this paper. The authors made a suggestion that the value of the factors be worked out by the methods of multifactor regression analysis.The class of the cultivated land in Korla city, Xinjiang Uygur Autonomous Region is defined by this system, which is composed of data input subsystem, mathematical model subsystem, spatial analysis subsystem, class assessment subsystem, data query subsystem and result output subsystem.
