The efficiency of medical record management was high increased . the storage capacitance of medical record information is enlarged , and it is very convenient to search and using these information . in the mis , statistic data of medical information was feed back in time , and the information integrality of circulating medical record was maintained 改变了手工操作和纯粹手工操作计算机化的病案管理模式，实现了计算机的一体化管理；提高了病案管理的工作效率；扩大了病案信息资料计算机的存储、检索及利用；及时反馈了医疗信息的统计数据；保证了病案流通病案资料保存的完整性。
Innovations : l . expaining the structure of the arable land classification information system and the basic functions of its subsystem systematically and concretely which can instruct the arable classification project with the principles and ways of information system . 2 . interpreting how to use the popular gis soft ware into the arable classification project in the arable classification subsystem ; 3 . developing the query and analytic subsystem by interface technology which takes efficient use of the result data poor ; 4 . learning the experience about the dynamic update of land information system in and out of china and forwarding the technological ways of the arable land classification result and the melting methods with rs and gps 农用地分等信息系统概括为分等、信息查询分析和动态更新三个子系统，用信息系统理论和方法指导农用地分等工作： 2 .在分等子系统中介绍利用通用地理信息系统平台实现农片i地分等工作的计算机化的技术方法; 3 .利用用户界面设计技术开发了查询分析子系统，高效利用了分等成果数据库; 4 .借鉴国内外土地信息系统动态更新的经验，提出农用地分等成果动态更新的技术方法和与rs和gps结合的方法
