本文对内蒙古自治区的自然条件,水土资源特征和38年耒大规模灌溉开发的主要成就作了概要介绍,系统提供了灌溉面积增长与粮食总产、单位面积产量的年度曲线图和水资源评价的几个特征数据:水资源总量(可利用量)、年径流深、时空变化、水资源开发利用率、灌溉水有效利用率及相应评价。分析认为,灌区水利工程的建设是发展内蒙古农牧业的主要途径、是干旱和半干旱地区农牧业开发的重要基础。也对发展内蒙古灌溉的某些经验进行了初步总结。
This paper gives an overview of the natural conditions of Inner Mongolia Autonomous Region, the characteristics of water and land resources and the major achievements in large-scale irrigation development over the past 38 years. The system provides an annual graph of irrigated area, total output of grain and yield per unit area, and water resources evaluation Several characteristic data: total amount of water resources (availability), annual runoff, temporal and spatial variation, development and utilization of water resources, effective utilization of irrigation water and the corresponding evaluation. According to the analysis, the construction of water conservancy projects in irrigation districts is the main way to develop agriculture and animal husbandry in Inner Mongolia and the important basis for the development of agriculture and animal husbandry in arid and semi-arid areas. It also made a preliminary summary of some experiences in developing irrigation in Inner Mongolia.
