克里雅河发源于昆仑山脉，位置在新疆的南部。2001年10月18-11月22日，中法联合考察队对克里雅河下游进行了深入的调查。根据标本采集与资料统计，克里雅河流域的野生脊椎动物约有98种(包括已绝迹的几种)，隶属于5纲，24目，48科。其中，鱼类约4种；两栖类1种；爬行类约4种；鸟类70种；兽类约19种。有一些动物的遗骸发掘自圆沙古城及附近的古墓地。本文探讨了物种绝迹的原因。
Kerry River originated in the Kunlun Mountains, located in southern Xinjiang. From October 18 to November 22, 2001, the Sino-French joint inspection team conducted an in-depth investigation of the lower Keriya River. According to the specimen collection and statistics, there are about 98 species of wild vertebrates in the Kalyya River Basin (including several species that have disappeared), belonging to 5 classes, 24 orders and 48 families. Among them, there are about 4 species of fish, 1 species of amphibians, 4 species of reptiles, 70 species of birds and 19 species of mammals. Some animal remains have been excavated from the ancient city of Roundabout and the nearby ancient cemetery. This article explores the reasons for species extinction.
