摘要
引黄灌区在我国经济社会发展中占有不可替代战略地位与作用。然而,黄灌区用水矛盾加剧、水肥利用效率普遍低以及面源污染问题突出,必须大力发展滴灌技术,提高对作物供水保障程度,促进绿色高效农业发展。黄灌区发展滴灌面临水源调控、泥沙过滤以及滴头抗堵技术难题,从而引发滴灌工程投资加大。以内蒙古科技与水利重大专项技术成果为基础,分析了上述几项因素对滴灌工程投资影响,并分析了降低滴灌投资途径,论述了黄灌区发展滴灌所产生经济、社会以及生态效益,可为黄灌区大面积推广滴灌提供参考。
The Yellow River irrigation areas play an irreplaceable strategic role in China's economic and social development.However,the contradiction between water demand and supply in the area is aggravated,the utilization efficiency of water and fertilizer is low,and the non-point source pollution is prominent.Therefore,it is necessary to vigorously develop drip irrigation,improve guarantee for crops irrigation,and promote the development of green and high-efficiency agriculture.The development of drip irrigation in the area is faced with the problems of water source storage,sediment filtration and proof emitter clogging,which leads to the increased investment in drip irrigation.Based on the technical achievements of Inner Mongolia's major science and technology and water conservancy project,this paper analyzes the influence of the above factors on investment of drip irrigation projects and the main ways to reduce investment of drip irrigation,and discusses the economic,social and ecological benefits from the development of drip irrigation in Yellow River irrigation areas,which can provide references for the large-scale promotion of drip irrigation in this area.
