| 摘 要： | 本文从冲洗定额的构成出发,定义从计划冲洗层的含水量达到最大田间持水量这一时刻起到计划冲洗层的含盐量达到允许含盐量止这段时间所需要的在冲洗定额中起输送冲洗作用的那部分水量为盐碱耕地生态需水定额。通过对塔里木河流域典型灌区的调查分析,初步确定塔里木河干流流域防治耕地盐碱化的生态需水定额约为1500 m3.hm-2,最后得出目前塔里木河干流流域防治耕地盐碱化的生态需水量约为0.97亿m3。 |
| 关 键 词： | 生态需水量 耕地盐碱化 塔里木河干流流域 |

| Abstract: | Based on the constitution of flush ration,the water needed during the period from the moisture content of planning flushed layer tends to limit field moisture capacity to the salt content of that tends to permitted salinity was defined,as ecological water demand of saline tilth.By analyzing the typical irrigated area of Tarim River basin,it was showed that the ration of ecological water demand that the main stream basin of Tarim River demand to prevent tilth salinization was about 1500m~(3)/·hm~(-2),and the amount of ecological water demand that the main stream basin of Tarim River demand to prevent and cure tilth salinization was about 97 million m~(3). |
| Keywords: | ecological water demand tilth salinization main stream basin of Tarim River |
