中国引调水工程及区域分布特点分析

收集了新中国成立以来已建或在建的 137 项引调水工程, 以 7 大地理分区为基础, 对各分区引调水工程数量、引水量等进行了初步统计, 分析了 7 大分区内引调水工程的特点。分析发现, 在经济较为发达的华东、 华北、 华中地区, 引调水工程数量较多, 设计年引水量较大, 工程任务涉及范围较广, 供水任务由灌溉逐渐扩展至工业、 生活及生态用水, 且有些工程规模较大, 如南水北调东中线一期工程等; 经济欠发达的西南、 西北等地区引调水工程数量及设计年引水量相对较低, 且供水对象侧重于生活用水和灌溉用水, 工程规模相对较小

Water transfer projects and the regional distribution characteristics analysis of China

Data about 137 water transfer projects built or under construction since the founding of new China was collected and analyzed in thisstudy. T he number, water volume transferred and other data of water transfer projects for the seven geographic divisions were analyzed statisti2cally. According to the analysis, water transfer projects had different characteristics for the seven divisions. T he number and designed water vol2ume to be transferred per year were relatively larger in developed areas such as east China, north China, central China, and the objects of watersupply has gradually extended to industrial, life and ecological water use from irrigation. Some projects in these areas had big scale, such as theSouth 2to2North Water Transfer and so on. The number and designed water division volume were relatively smaller in economic underdevelopedareas such as southwest and northwest regions of China. T he objects of water supply mainly focused on the domestic water supply and irriga2tion, and engineering scale was relatively smaller in these areas.
