摘 要: | 石羊河下游的民勤绿洲是武威盆地的主要天然屏障。近半个世纪来,在人类活动及自然环境退化的共同作用下,石羊河下游水质变差、流量持续下降,生态环境迅速恶化,严重制约石羊河下流流域的可持续发展。本研究通过综合分析已有资料,发掘石羊河下游生态环境恶化的原因,认为民勤生态环境治理应以治水为主:(1)结合中国现有政策,加快发展建设石羊河中游地区节水型农业,以保证下游充足的水量;(2)严格控制打井开采等不合理的人为活动;(3)大力发展水利工程,以保证河流流量及河道畅通。希望通过以上方案力争使民勤绿洲实现生态环境的良性循环。

Ecological Environment Construction and Sustainable Development of Minqin Oasis |
| |
Abstract: | Minqin oasis in the lower reaches of Shiyang River is the main nature barrier for Wuwei Basin. Nearly half of a century, because of double influence of human activity and natural factor, quantity of water in the lower reaches of Shiyang River decreased and ecological environment deteriorated, which influenced sustainable development of this area and surrounding area seriously. The author analyzed the current situation and reason of deteriorated ecological environment in this study. It showed that water must be the centre for control of ecological environment. Development step of water saving agriculture in middle reaches of Shiyang River should be increased. The lower reaches must have certain quantity of water. Unreasonable human activity must be controlled strictly. Minqin oasis was tried to realize virtuous circle of ecological environment. |
