改进世界土壤和土地资源的制图,发展一个能够传递精确的、有用的和实时的土壤-土地资源信息系统,有利于土地资源管理人员去制订规划和作出任何决策。标准化的信息也便于国际与国内的信息传递与交换。本研究工作以世界1:100万土壤-土地数字化数据库工作手册为准则。分四个阶段进行:1.土壤-土地图的编制;2.地图数字化和地图文件的建立;3.土壤-土地数字化数据库的建立;4.土壤-土地图及数据库信息的介评。
Improving the mapping of world soil and land resources and developing a soil-land resource information system that delivers accurate, useful and real-time information helps land resource managers to plan and make any decision. Standardized information also facilitates the transmission and exchange of information both nationally and internationally. The research work is based on the manual of 1: 1 million soil-land digital database in the world. It is divided into four stages: 1. Compilation of soil-land maps; 2. Digitization of maps and establishment of map files; 3. Establishment of soil-land digital databases; 4. Introduction of soil-land maps and database information.
