摘要
为提高南方湿润地区中小河流的径流计算的精度,充分合理利用附近或者下垫面相近流域的水文测站,解决无径流资料地区模拟径流成果可靠度的问题,同时为无资料地区兴建水利工程在运行提供合理以及科学的决策依据,提出了新安江产流和TANK汇流相结合的径流计算分析方法,并以铜山源溪流域为例,通过1962—2016年降雨和蒸发分析该地区径流,研究计算表明,该流域主要受梅雨控制,主汛期主要在4—7月,径流量占全年的58.9%,多年平均径流深为1198 mm,能充分反映出流域真实的径流特性;经与铜山源水文站实测12年径流成果对比分析,径流深年际变化规律一致,计算径流成果误差不超过2%,认为新安江产流和TANK汇流耦合的径流分析方法的计算成果是合理的,既能满足成果合理性的需要,又能补齐地区水文资料匮乏的短板,在降水丰沛且地区水文环境较差地区具有较好的可操作性。
In order to improve the accuracy of runoff calculation in humid area of southern China,make full use of hydrological stations of similar basins in nearby or underlying surface to solve the problem of reliability of simulated runoff results in areas without runoff data,and provide reasonable and scientific decision-making basis for construction of water conservancy project at areas without runoff data,this paper proposes the runoff calculation and analysis method combining Xin’anjiang River runoff and TANK confluence,and analyzes the runoff in this area through rainfall and evaporation from 1962 to 2016 by taking Tongshanyuan River Basin as an example.The research calculations show that the basin is mainly controlled by plum rain,its flood season is mainly from April to July,with the runoff accounting for 58.9%of the whole year,and its average runoff depth for many years is 1198 mm,which can fully reflect the real runoff characteristics of the basin.After comparison and analysis with the 12-year runoff results measured by the Tongshanyuan Hydrological Station,the inter-annual changes of runoff depth are consistent,and the error of runoff results is not more than 2%,so it is believed that the calculation results of the combined runoff analysis method are reasonable,which can not only meet the rationality of the results,but also repair the short board for the lack of hydrological data in the area.Therefore,in areas with abundant precipitation and poor regional hydrological environment,it has better applicability.
