| 中文摘要: |
| 在西北干旱内陆河流域,随着人口增长和经济发展,经济发展需水与生态环境需水成为水资源开发利用和生态环境保护的主要矛盾。因此,合理量化生态需水是西北干旱区水资源优化配置尚待解决的问题。文章讨论了西北干旱内陆河流域生态需水量的概念及估算原则,并结合生态需水量估算的地带性理论,提出了利用水量平衡原理估算生态需水量的计算方法。以甘肃民勤县为例,分析预测了生态需水量,为干旱区水资源合理配置提供科学依据。 |
| 英文摘要: |
| The conflict between ecological water demand and economic water demand has become critical in the arid regions in northwestern China with the population growth and economic development．The paper addressed the issue of ecological water demand in arid inland river basins．By describing the definition of ecological water demand in arid regions，and combining with RS and GIS technology，a method using the water balance theory was presented to estimate the ecological water demand．Minqin county in Gansu province was exemplified to analyze and forecast the ecological water demand．This study will be beneficial for the proper allocation of water resources in arid regions． |
