摘要：年度国土变更调查对国土资源管理至关重要，它关乎国家土地资源的合理利用与规划。传统调查方式成本高、周期长且受限因素多，难以频繁进行。然而，国土部门的工作又亟需详细的土地利用数据。遥感技术以其广覆盖、高精度的特点，为快速准确地获取大范围、复杂地貌的信息提供了可能。其数据时效性强、反馈迅速且成本低，有助于政府及时获取数据、分析趋势，为决策提供依据。本文通过实例研究，发现遥感技术在国土变更调查中展现出高效、准确、经济的优势，为调查工作带来了革命性变革，显著提升了效率和精度。
Abstract: The annual land change survey is crucial for land and resource management, as it relates to the rational utilization and planning of national land resources. Traditional survey methods have high costs, long cycles, and many limiting factors, making it difficult to conduct them frequently. However, the work of the land department urgently requires detailed land use data. Remote sensing technology, with its wide coverage and high accuracy, provides the possibility to quickly and accurately obtain information on large-scale and complex landforms. Its data has strong timeliness, fast feedback, and low cost, which helps the government to obtain data in a timely manner, analyze trends, and provide a basis for decision-making. Through case studies, this article finds that remote sensing technology has demonstrated efficient, accurate, and economical advantages in land change surveys, bringing revolutionary changes to survey work and significantly improving efficiency and accuracy.
