辽宁省湿地资源调查技术研究

Investigation and research of Wetland resources in Liaoning Province

通过对国内外既往湿地调查的方法及观点的研究,结合辽宁省湿地资源实际情况,以GPS、GIS和RS等技术的基础理论,结合林业专业技术,研究开发了以中巴卫星影像结合地形图,建立遥感解释标志,利用计算机自动判读,并辅以手持式GIS软件平台实地调绘校正的湿地调查技术方法。此技术经实际生产应用证明基础理论科学合理、操作简单易学,采集成果精度高。

The study at home and abroad through the previous wetland investigation methods and perspectives in the study of wetland resources in Liaoning Province,combined with the actual situation,to GPS,GIS and RS technology basic theory,combination of forestry professional technical,research and development with the CBERS satellite images combined with the topographic map,the establishment of remote interpretation marks,use the computer automatic interpretation,supplemented by handheld GIS software platform field survey correction wetland survey technical method.The practical application proves that the technology basic theory is scientific and reasonable,simple operation,high precision of sampling results.
