遥感技术在中国绿洲研究中的应用与展望

The Reconsideration And Prospect of Application of Remote Sensing Technique to Oasis Study in China

绿洲是干旱区独具特色的生态景观,但长期以来并未引起人们足够的重视,直到二十世纪末在中国才兴起绿洲研究之风。经过近10多年来的发展,中国绿洲研究在取得丰硕成果的同时,其研究内容和方法的发展也与遥感、GIS等现代对地观测技术的进步紧密联系在一起。本文对近年来中国绿洲研究中遥感技术应用状况,从绿洲的形成演变研究、绿洲水资源研究、绿洲土地资源利用与覆被变化研究、绿洲农业资源研究以及绿洲生态环境研究五个方面加以总结,进而分析遥感技术在绿洲学研究中存在的主要问题,并对未来遥感技术在绿洲学研究的应用发展方向进行分析。

Oasis is a special ecological landscape of arid land. But oasis study had not been regarded highly until end of the 19th century. In the past two decades, certain progress has been made in research of Chinese oasises and a series of achievements have been attained with the development of RS, GIS and other new land monitoring technology. Based on the domestic research literatures in recent years, five research areas were discussed respectively in this paper： the formation and development process of oasis, oasis water resources study, oasis LUCC study, oasis agriculture study and the ecological environment protection of the oasis. Through analyses, the authors pointed out the problems and brought forward some suggestions for the development of RS technology to the science of Chinese oasis.
