内陆干旱区河谷林生态需水研究

Ecological water demand of river valley forest in inland arid areas

研究了干旱区河谷林生态需水的概况,并以新疆阿尔泰山前平原布尔津河出山口以下河段的河谷林为例,采用参考作物法,计算了研究区内河谷林生态需水量。计算结果表明:该区域的生态需水总量为0.8亿m3,其中6-7月份河谷林需水量较大,月需水量约为全年的25%。这些成果可为流域生态保护与水资源合理配置提供重要的基础数据。

This paper analyzes the ecological water demand of fiver valley forest in inland arid areas. The paper takes the fiver valley forest of the reach downstream of the Buerjin River outlet in Ahay Mountains piedmont in Xinjiang as an example, and uses the reference crop method to calculate the ecological water demand of fiver valley forest in the research area. The results show that the ecological water demand in this area is 80 million ms. The water demand in June and July is relatively high and the amount of water demand in one month is about 1/4 of the amount in a whole year. These results provide important basic statistics for the watershed ecological protection and water resources allocation.
