宁夏引黄灌区末段区域农业水资源配置研究
Study on water resources allocation of agriculture in the end piece of Yellow River irrigation region in Ningxia
摘要
Abstract
In order to explore a new water resources allocation model of farmland,the paper takes the end piece of Yellow River irrigation region in Ningxia (Shizuishan City) as study area.Analysis the key reasons of water resources problems and study the water cycle of farmland based on natural-artificial dualistic hydrological cycle.Propose the new idea of leading water from ditches to drain as water resource of irrigation.Simulated with MATLAB optimization tool under restricts of water quality and quantity of farmland irrigation demand and also the red line of water resource management.The results show that under the constrain of irrigation water quality,the water using of Huinong canal,fifth drain,Tanglai canal and third drain are 438,92,82 and 31 million m3 which can save original irrigation water of Yellow River about 123 million m3.In the case of poor water quality of upstream drain,the water quality is the main constraint condition,otherwise,the water quantity is the main constraint condition.In order to make full use of drain water,the model of leading water from ditch to drain should be implemented under the principle of controlling quantity in the condition of poor drainwater and running out of drainwater in the condition of good drainwater respectively.The water resources use model of farmland can save fresh water and achieve multi-purpose water use.And also provide reference for water resources allocation in arid area.关键词
