【摘要】 随着“数字地球”的提出及现代地理信息系统的发展,越来越多的行业开始应用GIS技术解决本行业的问题。在信息社会的今天,各行各业都在进行数字化管理,我国土地信息数字化工程作为国家空间基础设施的一部分得到了长足发展,在这一背景下本文对县级土地利用数据库建设的过程和方法进行了研究。本文在GIS理论基础上结合3S技术,对建立县级土地利用数据库的方法进行了研究。利用DOM数据并参照1992年土地详查数据进行数据采集,提取耕地、交通道路网、农田水利设施等土地利用信息,建立土地利用数据库。作为土地利用基础信息为土地利用管理、规划提供详实的电子数据。在建立土地利用数据库过程中就GPS野外调查的应用及GPS数据在Google Earth中显示试验进行了探索;以村为单元进行调查,制作带有影像的宗地草图,并提出了一种保证地类代码完整性、正确性、消除地类代码中不必要信息的方法;同时还尝试了一种利用Access建立数据字典的捷径。这些创新性的探讨,为县级土地利用数据库建设提供了有益的经验。

【Abstract】 With the development of Digital Earth and GIS techniques, GIS is used widely to solve the problem in many fields. In the information-intensive society, the methods of digitalized management come to every walk of life. As a part of national spatial data infrastructure, the land information digitalized project made great achievements. Under the background, the process and method for building county-level land use database were studied.On the basis of GIS, the method for building county-level land use database was studied using 3S technology. According to the data of land detail survey and DOM data, land use information of field, traffic net and irrigation works were gathered. This information was used to build land use database. The database provides detail information for land use management and programming. In the process of building county-level land use database, the method of surveying with GPS and the GPS data displayed in Google Earth was studied. The survey was carried on taking the village as the unit the sketch map with image was made. The method of assuring integrality and correctness about land use code removing unnecessary information from land use code was studied. Meanwhile a shot cut of using Access to build DD was attempted.These innovation discussions have provided the beneficial experience for the county level land utilization database construction.
