【摘要】 以河西走廊为例研究了沙漠化地区的旅游开发对沙漠化的影响。研究发现,河西走廊主要的旅游资源的开发,都受到了沙漠生态环境空间上的制约,因此多数的旅游产品都集中在生态环境较好的绿洲上。通过计算旅游人口的用水量发现,旅游发展对沙漠化的直接影响很小,但旅游业在沙漠化地区不同流域地段的发展会对政府的环境政策产生不同的影响,从而间接影响到沙漠化的进程。更多还原

【Abstract】 The authors takes the Hexi Corridor of Gansu as a case to study the impact of tourism development to land desertification in desert areas.The results showed that the exploitation of tourism resources are restricted by the desert environment in Hexi Corridor,and the most of tourism products locate in oasis where the environment condition is preferable.Calculation on the water consumption by tourists confirms that the direct exacerbation of tourism to desertification is not obvious,but uneven tourism development in subareas of this region brings different policy effect which indirectly influence desertification processes.更多还原
