The Main Achievements and Technological Innovation on Land Resource Monitoring and Surveing Projeet of the New National Land and Resources Investigation

“土地资源监测调查工程”、“数字国土工程———县(市)级土地利用数据库建设”自1999年启动以来,运用“3S”等新技术手段,形成了一批土地资源调查、监测、评价的技术标准、规程和规范,初步查明了我国土地资源利用状况及其分布情况,获得了大量数据、文字、图件等调查成果,初步建立了土地利用和城市地价的动态监测体系,培育了一批具有特色和指导意义的示范工程。本文重点介绍了“两项工程”三年来取得的主要成果和工程实施中的主要技术创新。

By using new technology such as“3S”, a series of technical standards, regulations and criteria for land resource surveying, monitoring and evaluation were generated. Findings from the projects“Land Resources Monitoring and Surveying Program” and “Digital Territory Program——Database Establishment of Land Utilization at County or City Level' established new standard and creteria. The utilization condition and spatial distribution of land resource in China were clarified preliminarily. A wealth of data and maps were accumulated, the dynamic monitoring system of land utilization and urban land price were built - up, and a set of pilot programs were fostered. This paper introduces the achievements and technical innovation acquired during the implementation of these programs in the last three years.
