Abstract. To execute the overall protection and comprehensive treatment of natural resources, Chinese government has earnestly fulfilled its duties of centralized management and announced the overall plan for the construction of a survey and monitoring system for natural resources. Survey and monitoring of natural resources is the basic work of management of natural resources. Survey and monitoring of natural resources is a survey project of geospatial information for natural resources based on 3S spatial information technology, massive data resources and technical means. Survey of natural resources is classified into basic survey and special survey. Therein, the basic survey, based on the surface coverage, is principally to figure out the scope, area and ownership of all sorts of natural resources projected on the earth's surface. Data quality evaluation is significant means to ensure the authenticity and accuracy of the quality and results of the survey project for natural resources. This thesis studies the inspection and evaluation technology of quality and results, designs the quality model of basic survey for natural resources, including quality characteristics, quality requirements, and quality evaluation process. Apart from that, it selects the results of land survey in some regions of the country and conducts quality evaluation experiments of basic survey data, which verifies the applicability of the quality evaluation methods.
