摘要
土地利用变化作为全球变化的组成部分和重要原因,越来越受到人们的关注.而小区域的土地利用变化研究不仅有助于全球变化的整体深入研究,而且有助于当地的土地科学利用和经济合理发展.为此,本文在动态差分GPS技术和GIS技术的支持下,对试验区近17年间的土地利用变化进行了定量分析.具体过程为:通过动态差分GPS技术获得土地利用变化部分的基础数据,然后在GIS的支持下,对试验区的土地利用数量变化、土地利用程度变化、土地利用变化方向等方面进行了分析.结果表明:(1)GPS-RTK技术在小区域土地利用变化数据获取上具有测量精度高,效率快且费用低等优点.(2)试验区土地在数量、土地利用程度等方面存在着显著的变化.
As the component and important reason of the Whole World Changing, the land usechange is paid more attention by people. And it not merely contributes to the whole further investigation about the Whole World Changing that the study of the land use chang in the small area, contribute to local land utilize scientifically and economy develop rationally. For this reason, in this text we utilize the change to carry on quantitative analysis to the land during the past 17 years of trial zone under the support of GPSRTK technology and GIS technology. The concrete course：we first obtained land use change basic datas through the technology of GPS-RTK, analysed the change of the land quantity in the trial zone and the change of land utilize degree, and the direction of land use change by GIS. The result indicate that GPS-RTK technology have advantages of higher precision,lower expenses and more efficiency on obtaining the data of land use change in the small area. And there is remarkable change in such aspects as quantity, degree of utilizing in the trial zone.
