摘要
内蒙古西辽河流域是我国重要的粮食生产区,近年来随着玉米等作物种植面积的快速扩张,灌溉用水量大幅度增加,西辽河流域水资源开发利用严重超载,已经引发了地下水位大幅下降、河道断流、草场沙化和湖泊湿地萎缩等生态问题,已严重威胁下游通辽市的用水安全。以西辽河流域通辽市为研究对象,在统计通辽市用水现状及近40年地下水超采区变化的基础上,分析导致通辽市地下水严重超载,超采区不断扩大的影响因素;揭示水资源承载能力严重超载的主要原因。在此基础上,结合西辽河“量水而行”指导思想,提出通辽市未来水资源利用规划及相应的监管建议,为方案的制订及实施提供借鉴。
Xiliaohe River Basin of Inner Mongolia Autonomous Region is an important food production area in China.In recent years,with the rapid expansion of planting area of corn and other crops,irrigation water consumption has greatly increased.The serious overload of water resources development and utilization in the Xiliaohe River Basin has caused ecological problems such as groundwater table dropping dramat⁃ically,river break,grassland desertification and shrinkage of lake wetlands,which have seriously threatened water safety in downstream Tongliao City.This paper takes Tongliao City in Xiliaohe River Basin as the research object.On the basis of statistics of current situation of water consumption in Tongliao City and changes of groundwater overexploitation areas in recent forty years,the factors influencing groundwa⁃ter overload and continuous expansion of overexploitation areas in Tongliao City are analyzed.It further reveals the main reasons for serious overload of water resources carrying capacity.On these bases,the future planning of water resources utilization and corresponding regulatory suggestions of Tongliao City are put forward in combination with the guiding principle of“carrying out program by measuring water”.At the same time,it provides a reference for the formulation and implementation of the plan.
