| 摘 要： | 民勤绿洲是我国典型的内陆河尾闾自然景观,其格局的变化受人类活动和水文循环影响十分敏感.对此分析了民勤入境水量的逐年衰减、地下水位持续下降、荒漠草原超载放牧等引起绿洲衰变的主要成因及其变化规律,并初步估算了现状条件下水文及绿洲未来变化趋势.在分析确定绿洲恢复生态需水量的基础上,提出了实施流域综合治理,跨流域水资源合理配置的绿洲保护对策措施.

| Abstract: | The Minqin oasis is a typical landscape of continental river trail in China,and its spatial pattern is very sensitive to human activity and hydrologic cycle.Based on analysis of the reasons that cause oasis disintegration such as annual decrease of influx,under groundwater level to annually descend and vegetation descending and their rules.the tendency in the future of the hydrology and oasis under the current condition Primarily estimated.Based on the analysis of the ecolical requiring water quantity the countermeasures of basin comprehensive treatment,and optimal distribution of water resource were put forward. |
