by the 1960s, the Tarim River basin was built more than 30 million - cubic - meter reservoir seat, the entire river is basically dry, so that the lower reach;In addition to the precipitation is little, the minimum of the year with only about ten millimeters, while the evaporation capacity can be up to 4000 mm, followed by dried - up lake, 85 mu of populus diversifolia, branchy tamarisk and seabucrthorn (Mippophac rhamnoides) in natural vegetation, death, and every year it's still a 5 - to 7 - trees has been decreasing at a rate of 5000 mu of desertification of grassland, the herdsmen had to move the family, to the detriment of the refugees by the 1960s, the Tarim River basin was built more than 30 million - cubic - meter reservoir seat, the entire river is basically dry, so that the lower reach;In addition to the precipitation is little, the minimum of the year with only about ten millimeters, while the evaporation capacity can be up to 4000 mm, followed by dried - up lake, 85 mu of populus diversifolia, branchy tamarisk and seabucrthorn (Mippophac rhamnoides) in natural vegetation, death, and every year it's still a 5 - to 7 - trees has been decreasing at a rate of 5000 mu of desertification of grassland, the herdsmen had to move the family, to the detriment of the refugees . diversiform - leaved poplar forest area is also reduced in the forest habitat of the wildlife species that are reduced continuously, in the 1970s and a small amount of red deer and other wild animals in the diversiform - leaved poplar forest region, now almost extinct diversiform - leaved poplar forest area is also reduced in the forest habitat of the wildlife species that are reduced continuously, in the 1970s and a small amount of red deer and other wild animals in the diversiform - leaved poplar forest region, now almost extinct .
. green corridor on the downstream from the 1960s to 1980s.Tahe region desertification is spreading state
downstream is the worst of the lot, from 1958 to 1978 for 20 years, the area of desertification land in the proportion increased from 12 to 52 percent, and new dunes constantly formed, green corridor with extinction risk downstream is the worst of the lot, from 1958 to 1978 for 20 years, the area of desertification land in the proportion increased from 12 to 52 percent, and new dunes constantly formed, green corridor with extinction risk .
