前言利用柴达木盆地这个“露天实验室”,揭露现代盐类沉积规律,对寻找古代陆相盐类矿床有着十分重要的意义。许多人已经为之进行了努力。而利用卫星遥感资料进行研究,迄今还不多见。由于卫星的观察角度超出地球之外,使卫星影象具备了非一般地面工作所及之空前概括能力;又由于卫星资料的获取不受地面条件限制,对交通不便的柴达木区域,更显现出独特的优越性。初期的研究工作已经表明,在卫星影象上能够准确地判读出现代盐类沉积区的位置与范围。为便于进行柴达木区域的整体研究,特制了1:100万柴达木盆地卫星影象镶嵌图,使四十余万平方公里面积的山川湖泊一目了然(图1,系该镶嵌图之缩制照片)。
Preface Making use of the “open laboratory” in the Qaidam Basin to expose the law of modern salt deposition is of great significance to the search for ancient continental salt deposits. Many people have already worked hard for it. The use of satellite remote sensing data research so far is rare. Since the satellite’s observation angle is beyond the Earth, the satellite image has the unprecedented ability to summarize the non-general ground work. Moreover, since the access to satellite data is not restricted by the ground conditions, it is even more apparent to the Qaidam area where traffic is inconvenient A unique superiority. Initial work has shown that satellite imagery can accurately interpret the location and extent of the salt deposits in the modern age. In order to facilitate the overall study of the Qaidam region, a satellite image mosaic of 1: 1 million Qaidam Basin was specially made to make glacial mountains and lakes with an area of over 400,000 square kilometers (Figure 1) photo).
