一想到考古学家,人们头脑中就会浮现出灰头土脸拿着小铲子刨地的形象。在科技日新月异的时代,考古学家形象也大为改观了,他们手中的“枪炮”可真不一般。比如,英国考古学家研究撒哈拉沙漠绿洲中的古代文明。他们知道,那里应该保留了许多古代的城市、要塞和农田遗迹,但是在炎热、干燥、偏远的撒哈拉沙漠,人们很难进行野外考古工作。怎么办呢?他们找来高清晰度的卫星照片,在一片约2500平方千米的区域里,定位了158个古代主要居住点、184个墓地和30平方公里的田地,外加各种各样的灌溉系统。这些信息很难通过一次实地的遗址考察和挖掘工作获得。
When it comes to archeologists, the image of a gray shovel shaving ground emerges in the minds of people. In an age of rapid change in science and technology, the archeologists’ image has greatly improved, and the “guns” in their hands are truly unusual. For example, British archaeologists study ancient civilizations in the oasis of the Sahara Desert. They know that there should be many ancient cities, fortifications and farmland preserved, but it is very difficult to carry out field archeology in the hot, dry and remote Sahara. What to do? They took high-resolution satellite photos of 158 ancient main settlements, 184 cemeteries and 30 square kilometers of land in an area of about 2,500 square kilometers, plus a variety of Irrigation system. This information is difficult to obtain through a site survey and excavation work.
