Land is a material foundation which human survival depends on, and land resources is very important for the China development. The full use of land resources depends on the government efficient and scientific management and the understanding and treasuring of people for land resources, which are established on the foundation of fully understanding the quantities, quality and distribution of land resources.The spatial and information techniques such as Global Positioning System (GPS), Remote Sensing (RS), Geographical Information System (GIS), Computer Network etc and their integration promote the development of modem land management towards automatization, intelligentizing, scientizing, networking, and modernization, and offer the information acquirement, processing and analysis of land resources new technique means.GPS is widely applied in some fields of the national economy due to its features of all weather condition, high precision, automatization, and high efficiency. In this paper, some technique problems in application study of GPS technique in land management are discussed and analysed. The conception and feature of GPS technique are introduced, and the last developing status of the technique in the world is summarized. 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. The application of GPS technology in other fields of land management is discussed. The study in the paper offers land management work a scientific method, accords with the requirements of information age to the scientific management of land resources and sustainable development strategy, and has higher practical and spread value.
