[目的]开展基于生态水文变异特征的山东省济南市南部山区河流生态需水研究,为区域水资源综合管理和生态保护,加强黄河流域生态保护,促进黄河流域可持续发展提供理论依据.[方法]收集1979-2021年黄河下游济南南部山区的崮山站(北大沙河)和卧虎山站(玉符河)的径流量数据,采用累积距平法,Mann-Kendall(M-K)检验法,滑动T检验法,双累积曲线法多种统计分析方法,分析径流突变点;结合IHA-RVA法,研究济南南部山区河流径流变异特征和生态需水;通过分析河流生态需水满足度,研究区域生态水文和生态需水变异的主要影响因素,提出济南南部山区生态需水的保障措施.[结果]北大沙河和玉符河的径流量突变点为1996年,整体水文改变度分别为72.75％和69.42％,均属高度改变;北大沙河和玉符河的年生态需水分别为1.47×106,1.81×106m3.总体上,北大沙河月生态需水满足度平均为32.35％,玉符河月生态需水满足度平均为60.42％.[结论]济南南部山区在突变前后水文变异较大,总体的生态需水满足度整体偏低,可从河流生态调度和提高水资源利用效率方面加强河流生态需水保障.
Ecological Water Demand of Rivers in Southern Mountainous Area of Jinan Based on Characteristics of Ecohydrological Variation
[Objective]The study of river ecological water demand in the southern mountain area of Jinan City,Shandong Province based on ecohydrological variation characteristics was carried out to provide theoretical basis for regional water resources integrated management and ecological protection,strengthening ecological protection,and promoting sustainable development of the Yellow River basin.[Methods]The runoff data from Gushan station(Beidasha River)and Wohushan station(Yufu River)in the southern mountainous area of Jinan,located in the lower reaches of the Yellow River,were collected for the period 1979 to 2021.The study utilized the cumulative anomaly method,Mann-Kendall(M-K)test method,sliding T-test method,and double accumulation curve method to analyse abrupt changes in runoff.The IHA-RVA method was additionally used to examine variations in river runoff and ecological water demand.By comparing the rivers'satisfaction with ecological water demand,this paper investigated key factors influencing the regional ecohydrology and variations in ecological water demand while proposing protective measures to ensure adequate supply within the study area.[Results]The runoff mutation points of Beidasha River and Yufu River were observed in 1996,and the overall hydrological alteration degrees were determined to be 72.75％and 69.42％,respectively,indicating significant alterations in both rivers.The annual ecological water demand of Beidasha River and Yufu River was 1.47 × 106 m3 and 1.81 ×106 m3,respectively.Overall,the monthly ecological water demand satisfaction of the Beidasha River and Yufu River was 32.35％and 60.42％on average,respectively.[Conclusion]The hydrological variation in the southern mountainous area of Jinan was found to be large before and after the mutation,and the overall satisfaction of the ecological water demand was relatively low.The ecological water demand of rivers may be guaranteed by strengthening the ecological regulation of rivers and improving the efficiency of water resource utilisation.
