| 摘 要： | 水资源系统的风险分析与评价,是水资源可持续利用的关键问题,而对内陆河流域绿洲地区的水资源系统所面临的各种风险进行评价分析,成为研究的热点。以青海省香日德绿洲地区水资源系统为研究对象,建立该地区由水资源径流量的不确定性所造成的风险评价的2个模型,定量分析水资源的不确定性以及这种不确定性对绿洲主要用水行业(农业,防护林网)的风险影响。实例的计算结果表明:香日德绿洲地区的水资源径流量的不确定性造成的风险指标为0.362;对防护林网不完整造成的风险是0.289,而受水资源及防护林共同影响的农业结构存在的风险为0.294,水资源系统的整体生态风险为0.2925。 |

| Abstract: | Ecological risk analysis and its evaluation of water resources is a key problem of sustainable utilization of water resources, while that in oasis region of endorheic drainage is a hotspot. Taking water resources systems of Xiangride oasis in Qinghai as a research object, two models are established which reveal risk evaluation resulted from runoff amount uncertainty of water resources. The uncertainty of water resources and its influence on principal industries in oasis region are quantitatively analyzed. The results indicate that risk index because of runoff amount uncertainty of water resources is 0.362, that of protection forest net integrality is 0.289, and that of agricultural structure affected by water resources and protection forest synthetically is 0.294, whole ecological risk of water resources system is 0.2925. |
| Keywords: | oasis water resources system ecological risk protection forest net agricultural structure |
