灌溉用水量 meaning in Chinese
irrigation water capacity
Examples
- Abstract : the irrigation requirement and the available groundwater resources in the development area were assessed comprehensively . it was concluded that the groundwater resources in the area is sustainable
文摘:对双丰农业综合开发区的灌溉用水量和地下水可开采量进行了综合评价，指出本开发区地下水资源可以持续开发利用。 - Two aspects of the problem are discussed : one is that lift irrigation is no need when abstraction volume capability of canal head can meet the demand ; the other is that lift irrigation is in need when abstraction volume capability of canal head can not meet the demand
它包括两个方面：一是当渠首可引水量能满足灌区灌溉用水量时，则不需要提水灌溉；二是当渠首可引水量尚不能满足灌区灌溉用水量时，则需提水灌溉来补充灌溉用水量。 - After organizing the dynamo program , simulating the sd model , it has get the result that the using dimension area of soil is 5 . 72 104hm2 in the 30 years and the relation of the irrigating water volume for farmland , forest - sod land , the ecological water volume , other using water volume and the using area of soil
用dynamo语言编程，借助于计算机模拟模型，对绿洲sd模型进行运算，求解得出额济纳绿洲未来30年土地开发规模为5 . 72 10 ~ 4hm ~ 2 ，并计算出相应农田灌溉用水量、林草灌溉用水量、生态用水量，以及各类用水量与土地开发规模的关系。 - The premises of the simulation are that the runoff from upreach is 7 . 8 108m3 / a and the means of economization on water is in effect . when studied it was thought firstly the water for the lake area and the living plant of the oasis , then for forest - sod irrigation and farmland irrigation
模拟计算是以上游下泄水量7 . 8 10 ~ 8m ~ 3 a为前提条件，在实行节水措施，完善供水系统的情况下，首先满足维持和恢复一定规模湖泊面积，保证绿洲植被正常生长所需水量，然后考虑林草灌溉用水和农田灌溉用水量。
