摘要
海南省作为中国第一个生态示范省,例行“生态立省”原则,为深入推进海南生态文明建设、保护河流生态,对海南省三大江开展生态需水量研究具有重要的理论意义。以三大江流域7个主要水文站点的实测月流量长序列资料为基础,分别采用最小月平均流量法、7Q10法、逐月最小生态径流计算法及逐月频率计算法进行生态流量计算,通过对计算成果的分析与对比,并引入Tennant法进行检验,结果表明逐月最小生态径流计算法与逐月频率计算法的计算结果分别最符合最小生态流量与适宜生态流量的要求。推算得到三大江流域的最小生态需水量与适宜生态需水量,为流域水资源优化配置与规划调度提供科学依据。
As the first ecological demonstration province in China,Hainan province follows the principle of"building an ecological province"routinely.In order to further promote the construction of ecological civilization and protect the river ecology in Hainan,it is of great theoretical significance to carry out the research on the ecological water requirement of the three largest rivers in Hainan province.Based on the long sequence data of monthly flow obtained by the seven main hydrologic stations of three largest rivers,this paper calculates the ecological flow by the methods of monthly minimum mean flow,7Q10,monthly minimum ecological runoff computation and monthly frequency computation respectively.After analyzing,comparing,and testing by the Tennant method,it is showed that the result obtained by monthly minimum ecological runoff computation method and monthly frequency computation method meets the requirement of minimum ecological flow and appropriate ecological flow respectively.Thus,the minimum ecological water requirement and the appropriate ecological water requirement of the three largest rivers can be calculated,which can provide scientific basis for the optimal allocation and scheduling of water resources in the river basin.
