摘要
20世纪,塔克拉玛干沙漠环境的变迁,出现了由自然因素影响为主到人为因素影响为主的转变,表现为生物种群,分布和数量的急剧减少;水系空间分布格局的全面改变;河流下游区雏形沙丘的迅速发育和局部区域小气候环境的恶化等。环境恶化的趋势仍在继续发展。增强人类对大自然的改造作用,减少人类对大自然的破坏影响,是对沙漠环境进行调节控制的有效途径。
In the 20th Century the influence on the Taklamakan Desert environment has been changed to artificial factors from natural factors, which shows as the sharp decrease of population, distribution and amount of living beings, the complete change of spatial distribution pattern of water system, the rapid development of embryonic sand dunes in the lower areas of river and the deterioration of microclimate environment in some areas. The deterioration of environment is still advancing. The effective way for adjusting and controlling desert environment is to streng then human effect on remaking nature and decrease human effect on destroying nature.
