水环境约束下的干旱区绿洲城镇化

Analysis of effect of dry land water environment on oasis urbanization

干旱区绿洲生态环境脆弱,生态问题突出,水与绿洲的生死存亡息息相关,是绿洲存在的关键因子。研究绿洲城镇化过程中的水资源问题,揭示其对本来就脆弱的绿洲水环境的影响强度、机制和规律,为克服城镇化过程中可能出现的盲目性及其对绿洲环境的危害,为绿洲城镇化的健康、稳定和合理发展以及加强绿洲生态环境建设,实现绿洲社会经济的持续发展以及最终实现绿洲现代化,有着现实的、长远的积极意义。本文主要就绿洲水资源的特点及其与城镇化之间的相互影响做了详细的分析。在论述绿洲水资源特点的基础上,全面分析了水资源对绿洲城镇化的影响和绿洲城镇化对水资源的影响,并提出适度的城镇化有利于绿洲水资源问题的好转。

Because of the vulnerability of the eco-system on the oasis in the arid area, the ecological environment is getting much worse, particularly the water, as a vitally important resource to the existence of the oasis, is in face of severe situation at present. Therefore, to study the water resource worsening continuously with the accelerating development of the urbanization, as well as to reveal the scope, intensity, mechanism of the relevant effects caused by urbanization on the oasis,so as to alleviate the harmful impacts occurring during such urbanization, and at the same time, strengthen the ecological rehabilitation on the oasis, is most significant for the oasis to achieve the goal of sustainable development and modernization in the long term. The paper concentrates on the detailed analysis of the water resources and the mutual interaction between water and urbanization on the oasis. Based on the comprehensive analysis of the characteristics of the water and the urbanization situation, the author expounds his view that reasonable and proper urbanization is favorable for the better of the water resource on the oasis.
