遥感技术在裸露型泥炭的资源普查中已得到应用。但在埋藏型泥炭资源普查中的应用,还是一个值得研究的问题。中国的泥炭资源有五分之一属于埋藏型泥炭,如果遥感技术能够在埋藏型泥炭资源普查中得到有效应用,将具有重要的经济意义。

A successful example of application of the remote sensing technique to buried poat district is presented in this paper,as a result of investigation for peatresources of southern Anhui.The peat in the surveyed district is completely coveredby the soil of late Holocene.The overburden is about 1 to 8 meters.On theearth surface the distribution and boundary of the peat field can not be located.Therefore it is more difficult to investigate these peat resources by using conventional geological method.By means of systematic analysis of landsat image and false colouroptical enhancement for the specific objective,the author acquired theimage mark by which the buried peat district being identified.Soon afterward,a series of checking for the identification mark have been made,and the reliability of the mark has been established.Based on the mark which had been confirmed by ac-tual data,the boundary of buried peat district was accurately located,and the peat reserves were estimated and evaluated.These peat resources were found.This result showsthat by means of landsat image,the surveying on small scale for the buried peatfield is feasible.Finally,several technical issues are also discussed in this paper,including theknowledge for forming mechanism of image mark of buried peat district and theconcept "perspective information",etc.
