Google Earth和3S技术在喀斯特示范农业规划中的应用初探

A Preliminary Application of Google Earth and 3S Technology in Karst Agricultural Demonstration Planning

本文基于Google Earth平台并综合一系列的辅助分析工具,尝试建立Google Earth与3S技术综合应用于喀斯特示范农业规划的技术框架,提出了一套基于Google Earth的一般地理专题图的制图技术流程,并讨论其关键技术。最后以六盘水市米箩乡猕猴桃产学研基地进行了应用研究,旨在为部分缺乏基础资料的喀斯特地区农业规划、勘察设计提供有效指导,结果表明:Google Earth平台可成为喀斯特资料稀缺区农业规划的有效信息收集手段,文中所提出的技术框架流程具有较好的可操作性,研究区下载的高清遥感影像可满足1∶2 000比例尺的制图要求,大大节约了勘测成本,有利推动了工作效率。

Based on Google Earth platform with a series of auxiliary analysis tools,this paper attempts to establish a framework process for integrated application to karst agricultural demonstration planning,put forward a set of graphics process of general geographical thematic map and discuss its key technologies,Taking the kiwi fruit CEEUSRO base in Miluo Township of Liupanshui City as an example,an applied research has been conducted in order to provide effective guidance on agricultural planning and survey in data-lacked karst areas.The results show that Google Earth platform can be used to collect effective information for agricultural planning in karst areas,especially in data scarcity areas.The technical framework process proposed in this paper has good operability.The highresolution remote sensing image download from Google Earth platform can meet the needs of the 1∶ 2 000 topographic map requirements,which can greatly save the survey costs and be conducive to the work efficiency.
