水有效性 meaning in Chinese

water availability

Crop - water relationship and availability of field irrigation water based on swap model simulation were studied in two areas of a largest - sized irrigation district - hetao irrigation district in the western arid area of china respectively according to its unique characteristics of hydrology and water resources so as to provide a theoretical basis and technical support for its water - saving transformation and agricultural sustainable development . the results can also be applied to other areas with similar natural and agricultural conditions
本文针对我国西部干旱区的特大型灌区?河套灌区所具有的独特水文水资源条件，选择两个典型区域分别进行了作物-水分关系和基于swap模型模拟的田间灌溉水有效性研究，以揭示和确立水分对干旱区作物产量的影响和量化表达与浅地下水位灌区农田水分运移转化规律和灌溉水对作物生长利用效率的评价方法，为河套灌区以节水为中心的技术改造和可持续发展提供理论基础和技术支撑。
