摘要
土地利用变化日益成为土地资源研究的重点,而土地利用格局及其变化的研究对于生态环境、土地利用等方面具有重要意义。"3S"技术具有很强的空间数据的获取、分析和处理能力,这为研究提供了强有力的支撑。本文从信息源、工具与载体、空间定位等三个方面综述"3S"技术在土地利用格局研究中的应用情况,并分析在应用中的优缺点。最后,对"3S"技术在土地利用格局研究中的应用提出建议和展望。
The change of land use is the main field in the research of land resource. And the land use pattern and change is crucial to ecology and environment and land use. Owing to its capacity of spatial datum attaining, analyzing and managing, “3S” technology gives a great hand to the resaerch of land use pattern. In this paper, the three aspects of the application of “3S” technology in the study are expatiated, which are information source, tool and carrier and spatial orientation. At last, the future of application of “3S” technology in land use pattern is forward to.
