摘要:

基于同古孜洛克和乌鲁瓦提水文站1960—2016年年尺度与月尺度径流数据,分别采用均值标准差法和模糊集对分析法对和田河2大支流进行丰枯类别评价,并在此基础上优选模糊集对法和Copula函数法计算2条源流径流丰枯组合概率,同时分析2支流间互补的优劣性。结果表明:模糊集对法考虑了年内径流贡献度使评价结果更客观,玉龙喀什河枯水年占比最高,应提高枯水期水资源利用,喀拉喀什河平水年占比最高,表明喀拉喀什河常年来水稳定;统计法和Copula函数得出的丰枯概率存在差异性与数据使用、划分方式及源流区域海拔有关,2种方法结果均表现为异步丰枯概率大于同步丰枯概率,两支流具有较好互补性。该结果能更清晰的描述和田河径流丰枯状态及丰枯组合特性,可为和田河流域水资源调度提供参考和决策依据。

Abstract:

Studies on the different contributions of the runoff of the Hotan River in different time periods and synchronous-asynchronous encounter probability can provide a reference for the balance of industrial water, potable water, and water ecological environment and the improvement of water resource utilization efficiency in the Hotan River Basin. Mean standard deviation and fuzzy set pair analysis methods are applied to evaluate the runoff wetness-dryness of the Yulong Kashi River and the Karakashi River. The possibility of inter-runoff water transfer and synchronous-asynchronous encounter probability is analyzed on the basis of fuzzy set pair method and copula function. The fuzzy set pair method reveals that the Yulong Kashi River had 10 and 26 wet and dry years, respectively. By comparison, the mean standard deviation method shows that the Yulong Kashi River had 15 and 20 wet and dry years, respectively. The Karakash River had 9 wet years. Furthermore, 18 and 26 times in dry years were observed. In the fuzzy set pair method, the contribution of annual runoff and the influence of time history distribution are considered. Thus, evaluation results are more objective, and the difference in the probability of abundance and dryness obtained by the statistical method and the copula function is the same as the data scale is related to the way of dividing the abundance and dryness. The results of the two methods demonstrate that the probability of asynchronous abundance and dryness is greater than that of synchronous abundance and dryness, and the two tributaries have good complementarity. They can more clearly describe the high and low runoff status and the characteristics of high and low runoff in the Hotan River. They can also provide a basis for making decisions on water resource dispatch in the Hotan River Basin.
