| Abstract: | Ecological problems are major factors restricting sustainable development in Hexi Corridor. Reduction of headwater conservation forestry in Qilian Mountain at southern Hexi,man-made ecological wreckage in oasis of middle part of Hexi and desertification in desert region at northerm Hexi are major ecological problems.Natural factors and man-made factors jointly lead deterioration of eco-environment in Hexi Corridor.Aiming at sustainable development, rational disposal of water and land resources\, increasing the investment\, adjustment of economic stvucture\, control of population\, enhancing the environment protection sense and law sense of the public should be taken. \ \ |
