The second approach is to develop real estate management information system ( mis ) based on webgis . this system should include ten important systems , that is land mis , real estate demolishing mis , real estate development mis , real estate transaction mis , real estate lease mis , property mis , special houses mis , real estate enterprise mis , real estate file mis and real estate datum mis . the third approach is to build network , which includes intranet and internet 本文通过分析，认为服务于房地产业政府信息化的房地产管理信息系统应包括十个重要的子系统，包括:土地资源管理信息系统、房地产拆迁管理信息系统、房地产开发项目管理信息系统、房地产交易管理信息系统、房地产租赁管理信息系统、物业管理信息系统、特殊住房管理信息系统、房地产企业管理信息系统、房地产档案管理信息系统、房地产资料管理信息系统等:三是房地产业政府信息化建设的应用平台?网络建设。
This paper , starting with a review of the history and status quo of the study on land resources in china , argues that there are 10 foci in the present study of land resources at present , namely : multidisciplinary perspectives ; theoretical pursuits ; land use planning and land arrangement ; land use and resources - environment safety ; sustainable utilization of land resources ; management of land resources ; protection of farmland resources and food safety ; structural adjustment and optimal distribution of land ; land use and cover change ( lucc ) ; and application of modem technology to the exploitation and utilization of land resources 摘要文章阐述了中国土地资源研究的历史，分析了中国土地资源研究的现状，指出目前中国土地资源的研究主要集中在以下几个方面：众多的学科研究土地资源；土地资源的理论研究；土地利用规划与土地整理研究；土地利用与资源环境安全研究；土地资源可持续利用研究；土地资源管理研究；耕地资源保护与食物安全研究；土地结构调整与优化配置研究；土地利用土地覆被变化( lucc )研究；现代化技术手段在土地资源开发利用中的应用研究等。
Therefore , for realizing modernization of land resources management of our nation quickly , being meet for the need of land management department , this paper utilized that computer software technology was combined with the development tool of geography information system ( gis ) to create the land resources ecological economical suitability evaluation system ( lres ) , and attempted scientific management to land resources of zhao zhuang village yan er gou watershed yenan city in order to realize in control exactly of land use present condition in time and supply with decision - making support for this areas 为了加快实现我国土地资源管理的现代化步伐，满足土地管理部门对土地资源管理的需求，实现土地资源生态经济适宜性评价的实时性、动态性。作者利用计算机技术与地理信息系统技术相结合，建立了延安燕儿沟流域赵庄村的土地生态经济适宜性评价系统，尝试了对该村的土地资源进行科学管理，用以实现对土地利用现状及经营情况及时、准确地掌握，为相关人员提供信息服务和技术支撑。
Along with the advancement of technology , human are changing all aspects of environment at unprecedented speed the change of the utilizing land resource make the style of utilizing land resource change with each passing day for the land manager , as the traditional mode of manage can not adapt the change of utilizing land resource , they need a sort of land resource management information system which can update graph and data at real timeo the appearance and development of " 3s " ( remote sensing globe position system geography information system ) technology improve the change from traditional map to digital map , and offer the platform on which the land resource management information system can be developed which can satisfy the manager ' s requirement , and make it possible that develop the land resource management information system by the manner of system integration the article set forth the method and technology of developing the land resource management information system from the aspects of the manner of development the instruments of integrated development the design of system the data ' s organization the technology of integrated development 随着科学技术进步的速度越来越快，人类正以空前的速度改变着自然环境及其各个方面，人类对土地资源的利用也发生着日新月异的变化，使得土地资源的利用类型随时随地发生改变，对于土地管理者来说，传统的管理模式已经不能够适应当前土地利用的变化速度，急需一种能够实时更新图形和数据的土地资源管理信息系统。 “ 3s ” (遥感技术、全球定位系统、地理信息系统)技术的出现和发展，推动了传统地图向动态的数字化现代地图的变革，为建立满足当代土地管理者需求的土地资源管理信息系统提供了可能的平台，使得采用系统集成方式进行土地资源管理信息系统开发成为可能。本文主要从开发方式的选择、集成开发工具、系统设计、数据组织、集成开发技术等五个方面阐述开发土地资源管理信息系统的方法及相关技术。
The manner of development : by comparing of the independence development and the second development , the author draw the conclusion that the second integrated development took full advantage of the function of gis software as a tool and the application system developed through the second integrated development has fine performance and stability , ) so the author put forward a model of using the second integrated development which can develop the land resource management information system 开发方式的选择：通过对自主开发和二次开发两种开发方式各自特点的分析比较，指出：集成二次开发充分利用了工具型gis软件的功能，开发出的应用型gis系统的系统性能和稳定性好，提出使用集成二次开发方式进行土地资源管理信息系统的开发。
The present application status of gps technique in land management is expounded , especially , the status of establishing land use database for county ( city ) level is emphatically introduced , and its main problems are analysed . the conception , characteristic , and application of all kinds of positioning methods using gps are introduced . the technique scheme of land surveying control network and the technique scheme of acquiring high accuracy data of land resources using gps technique are designed , and the realization method of key technique is indicated 阐述了目前我国gps技术在土地资源管理中的应用状况，重点介绍了县(市)级土地利用数据库建设的现状，分析其存在的主要问题；介绍了各种gps定位方法的概念、特点及应用；研究设计了土地测量控制网的技术方案和gps技术获取高精度土地资源变化数据的技术方案，指出了关键技术的实现方法；探索了gps技术在土地管理中其它方面的应用。
The technology of integrated development : first , the author introduces some conceptions of the technology of object - oriented which related the development of this system and especially studies technology of ole . at last , the author carry out the second integration development of the land resource management information system using the technology of ole 集成开发技术：首先介绍了本系统开发所涉及到的一些面向对象技术的概念，重点研究了ole技术，最后运用ole技术进行了土地资源管理信息系统的集成二次开
