一、目的和意义新疆水土资源分布的特点之一,是高山区降水及地表径流丰沛,但气候,地形不宜农耕。广大山前丘陵,小河众多而洪枯悬殊,宜农地有限,山前冲洪扇及其平原,降水少,径流分布和季节分配不平衡、影响作物适时适量灌溉。因此开发地下水,发展喷、滴灌、对农业现代化具有重要意义。新疆地下水的又一特点之一是:承压水质优而开采经济,无论山前丘陵河谷、或洪积扇及冲积平原,都是大面积小入渗量的山前雨雪融水,与小面积大开采量的农田供水相对应,因此,分析小区开采水量的动力学关系,探讨其不同条件下,小区井群可采水量与断面流量关系,对于可采水量的保证性提供定量分析的理论和科学依据,是必要而有意义的研究工作。
First, the purpose and significance One of the characteristics of the distribution of land and water resources in Xinjiang is the abundance of precipitation and surface runoff in high mountain areas, but the climate and topography are not suitable for farming. The majority of hillocks and hills have many floods and great disparities, and should be limited to farmland. Precipitating flood fans and their plains, less precipitation, uneven runoff distribution and seasonal distribution affect timely and proper irrigation of crops. Therefore, the development of groundwater, the development of spray, drip irrigation, is of great significance to the modernization of agriculture. One of the characteristics of Xinjiang’s groundwater is that the pressure water quality is excellent and the mining economy is good. No matter the piedmont hills and valleys, alluvial fans or alluvial plain, they are all small and infiltrated piedmont rain and snow melt water, Therefore, this paper analyzes the dynamic relationship between plot mining water quantity, and discusses the relationship between recoverable water quantity and cross-section flow rate of the well group in different conditions, and provides a quantitative analysis theory for the assurance of recoverable water quantity And scientific basis, is necessary and meaningful research.
