基于“3S”技术的土地利用时空变化研究

Study on Spatial Temporal Features of Land Use Change Based on Technologies of "3S"

土地利用/土地覆被变化是全球环境变化研究的核心领域.“3S”技术是进行资源环境研究的重要技术手段.本文基于“3S”技术,对土地利用的时间动态特征和空间动态特征进行了定量分析.以秦皇岛市为例,通过数学建模,揭示了研究区土地利用变化规律,为秦皇岛市实现生态环境目标提供理论依据.

The research of land use/cover is a core and focus point for studying on the globe changes. '3S' is a very important for natural resource investigation and environment protection. Take Qinhuangdao for example, the spatial-temporal change of land use was studied based on the technology of '3S' in this paper. The order of land use has showed by studying the mathematical methodology on land use change, which provides the theoretic basis for realizing ecological target in Qinhuangdao.
