タリム川
The centre of the range of Tugay vegetation is the Tarim Basin in north-western China, where the Tarim Huyanglin nature reserve in the middle reaches of the Tarim River holds the largest areas of intact Tugay forests, with a 1993 estimate of about 61% of the total. The Central Asian countries hold another 31%, with smaller areas remaining in the Middle East and Pakistan. Tugais also occur in the Caucasus.
