自1973年以来,中国科学院、中国科学探险协会曾先后于1973、1974年,1982～1984年、1991和1993年在雅鲁藏布大峡谷地区进行综合科学考察,先后徒步到达过派一白马格熊、希让—甘代的沿雅鲁藏布大峡谷河段,取得了丰硕的科学成果。参加科学考察的科学家和新闻工作为人类首次徒步全程穿越雅鲁藏布大峡谷打下了基础,他们不愧为先行者。然而,在雅鲁藏布大峡谷核心河段,即自白马格熊—扎曲—甘代的沿河地段约90多公里,由于自然条件太艰险,科学家们并未能涉足。1998年10月下旬至12月初,在中国科学院、中国科协的领导和关怀下,中国科学探险协会和珠海天年高科技国际公司主办,由 Since 1973, Chinese Academy of Sciences and China Association of Scientific Expeditions successively conducted comprehensive scientific investigation in the Grand Canyon of Brahmaputra in 1973, 1974, 1982-1984, 1991 and 1993, Xiong, Xi Jean - Gandai along the Yarlung Zangbo Grand Canyon River, has achieved fruitful scientific results. Scientists and journalists attending scientific expedition laid the foundation for the first human beings to walk through the Brahmaputra Grand Canyon and they deserved to be pioneers. However, at the core of the Yarlung Zangbo Grand Canyon, about 90 kilometers along the river along the White Horse Grizzly-Zha-Gandai, scientists were not able to set foot in due to too difficult natural conditions. From late October to early December 1998, under the leadership and care of the Chinese Academy of Sciences and China Association for Science and Technology, hosted by China Association of Scientific Expeditions and Zhuhai Tianyuan High-tech International Company,
