AbstractTo improve the timeliness and the accuracy of benchmark land price assessmentand the evaluation data, to promote the optimal allocation of national resources basedon the information technology and automation of land grading and evaluation, and forthe country to play an active role in the regulation of the land market, this paperdesigned the development of the city benchmark land price system and completed it.After the research on the domestic and international status of development forbenchmark land price evaluation system, a specific goal of development was made.On condition of that, the paper used the technology of computer and GIS, combinedwith land and real estate economics, and the way of "rating zoning methods at price ",combined with the study of benchmark land classification and valuation methods, aswell as the past experience of valuation system, finally completed the development.The system uses ArcEngien and C # language programming working based on theVisual Studio platform, to achieve a multiple of function, which includes the systeminterface management, fundamental GIS operation, land grading and evaluation, andthe information query. This paper took the city Xinyi for an example, made it thebenchmark land price assessment, and from which the average income of urban landin different regions is reflected and useful references come out for local governmentto make plans and management.

1绪论1.1研究意义随着我国城镇化水平的不断提高，城镇国有土地使用制度不断完善，土地市场正蓬勃发展。土地价格又是调控土地市场的重要手段，因此我国已经形成以基准地价为核心的城市地价体系，并通过对我国大、中、小城市地价的综合评估，提出了自己的基准地价体系。随着近年研究和实践的深入，基准地价更新方法也在逐步完善，大中城市的地价更新日渐成熟。而较为落后的中小城市，尤其对西部小城镇而言，由于受土地市场发育迟缓、管理工作滞后等问题的困扰，现行的更新方法并不能完全适应当地实际， 方法实施困难导致估价工作难以开展的现象非常普遍[1]。在城镇的基准地价评估过程中难免会出现评估地价缺乏时效性、脱离实际的现象，这样既不利于对城市土地市场的观察，也不利于国家调控和发挥导向性作用。因此，本文将运用计算机技术和 GIS 技术，结合土地、房地产经济学，通过对基准地价定级、估价方法的研究，借鉴以往基准地价评估经验，建立一套基准地价评估系统。开发出集地图管理、基础操作、土地定级估价和信息查询功能为一体的信息系统，并通过此系统，加快对中小城镇基准地价评估的速度，提高时效性。提高基准地价评估数据的准确度，为国家优化资源、准确发挥其调控手段发挥积极作用。
