安陆站–隔蒲潭站区间水量不平衡研究
Study on Water Imbalance between Anlu Station and Geputan Station

天然径流量是区域水资源分析评价工作的基础，但随着水资源的开发利用，湖北省多个区间出现了水量不平衡的现象。本文以安陆站–隔蒲潭站区间为例，从地下水与地表水交换、分项还原计算原理入手，分析论证了区间水量不平衡产生的因素及程度；建立了区间水量平衡模型、二参数月水量平衡模型，应用该模型对系统误差造成的水量不平衡进行了校正，校正后的区间水量不平衡现象出现了缓解甚至逆转；径流修正后，建立新的降水径流关系线拟合效果好。此研究方案的思路清晰、可操作性强，可为其他地区的水量不平衡提供参考，也可为水资源管理、评价等工作提供依据。
Natural runoff volume serves as the foundation for regional water resources analysis and evaluation. However, with the development and utilization of water resources, the phenomenon of water imbalance has emerged in multiple intervals within Hubei Province. Taking the interval between Anlu Station and Geputan Station as an example, this paper commences from the exchange between groundwater and surface water and the principle of itemized reduction calculation, and analyzes the factors and extent contributing to water imbalance within the interval. Moreover, a water balance model for the interval and a two-parameter monthly water balance model are established. The application of this model corrects the water imbalance caused by systematic errors, and the water imbalance phenomenon after correction has witnessed alleviation or even reversal. After the runoff correction, the establishment of a new precipitation-runoff relationship curve exhibits a better fitting effect. The research scheme in this paper is characterized by clear thinking and strong operability, which can offer references for water imbalance in other regions and provide a basis for water resources management and evaluation.
