摘要

以2005年为现状年，用定额法、潜水蒸发法和地下水储量变化法估算出塔里木河十流的生态需水量，其结果分别为33.89×108 m3,23.97×108 m3和33.07×108 m3，通过分析得到现状年合理的生态需水量为30.31×108 m3。并根据阿克苏、沙雅、库车、轮台、库尔勒、尉犁和铁十里克7个气象站1995-2004年的月平均蒸发量，采用阿维里扬诺夫公式和群克水均衡场公式对塔里木河十流天然植被的月潜水蒸发量进行计算，在此基础上计算月生态需水量。通过分析发现，植被生长期(4-10月)的生态需水量占全年生态需水量的86%，尤其是植被生长旺盛时期的5-8月的生态需水量占全年的59%根据制定的生态恢复方案，用定额法和潜水蒸发法预测3个口标年的生态需水量，将两者计算结果加以算术平均，得到2010,2015及2020年合理的生态需水量分别为31.88×108 m3,34.08×108 m3及36.84×108 m3，为塔里木河流域的水资源优化配置提供科学依据。

Abstract

In this paper, the ecological water demand in the mainstream of the Tarim River under the current year 2005 was calculated with the quota-area method, the phreatic evaporation method and the groundwater storage quantity change method. The ecological water demands calculated with these methods are 33.89×108 m3, 23.97×108 m3; and 33.07×108 m3;, respectively. In comparison, the reasonable ecological water demand is 30.31×108 m3. Besides, the monthly ecological demand in the mainstream of the Tarim River was acquired on the basis of monthly phreatic evaporation calculated by Aweliyongrufe formula and Qunke formula based on monthly average evaporation (1995-2004) from Aksu, Shaya, Ruche, Luntai, Korla, Yuli and Tikanlik weather stations. Analyzing the monthly ecological water demand, it was found that the ecological water demand in the growing season(from April to October) was 86% of the annual total, with May, June, July and August accpunting for 59% of the annual total. According to the ecological restoration scheme formulated, the ecological water demand of the three target years were forecasted with the quota-area method and the phreatic evaporation method. The reasonable ecological water demand in 2010, 2015 and 2020 are 31.88×108 m3, 34.08×108 m3 and 36.84×108 m3, respectively by averaging the two results. This study provides a scientific basis for optimal allocation of water resources in the Tarim River Basin.

Key words： ecological water demand; groundwater depth; natural vegetation; phreatic evaporation; Tarim River
