Vast research is conducted around the world in order to determine the effects of climate change on water resources. Determining and preserving the rechanging characteristics of karstic springs has an important place in water resources management studies. In the present study, the variation trends of climate parameters, affecting the discharge trend of the Tacin karstic spring in Kayseri, Turkey and the spring discharge, were analyzed. For this purpose, the monthly mean discharge flow of the karstic spring between the years 1975 and 2017 and the monthly average temperatures and precipitation parameters belonging to the meteorological stations close to the spring (Kayseri, Pınarbaşı, Gemerek and Şarkışla) were adopted. In the trend analyses, the non-parametric Spearman Rho (SR), Mann Kendall (MK) and Şen-Innovative Trend analysis tests (Şen-ITA) were used in addition to the non-linear tests. Accordingly, a reduction was observed in the change trend of the precipitation parameter of Pınarbaşı and Kayseri stations and an increase in the respective measure of the Gemerek and Şarkışla stations while a noticeable decrease took place in the flow discharge of the Tacin karstic spring. The temperature parameter underwent a similar increase in all of the four stations meanwhile. Consequently, the decrease trend in the flow discharges of the Tacin karstic aquifer was inferred to stem from the reduction in the precipitation trend, observed in the southern part of the karstic aquifer.

世界各地进行了大量研究，以确定气候变化对水资源的影响。确定和保存岩溶泉水的再变化特征在水资源管理研究中占有重要地位。本研究对影响土耳其开塞利Tacin岩溶泉流量和泉流量的气候参数变化趋势进行了分析。为此，采用了 1975 年至 2017 年间岩溶泉的月平均流量以及属于靠近泉水的气象站（开塞利、Pınarbaşı、Gemerek 和 Şarkışla）的月平均温度和降水参数。在趋势分析中，非参数 Spearman Rho (SR)，除了非线性测试之外，还使用了 Mann Kendall (MK) 和 Şen-Innovative Trend 分析测试 (Şen-ITA)。相应地，观察到 Pınarbaşı 和 Kayseri 站降水参数的变化趋势减少，而 Gemerek 和 Şarkışla 站的相应测量值增加，而 Tacin 岩溶泉的流量明显减少。同时，所有四个站点的温度参数都经历了类似的增加。因此，推断 Tacin 岩溶含水层流量减少的趋势源于在岩溶含水层南部观察到的降水趋势的减少。观察到 Pınarbaşı 和 Kayseri 站降水参数的变化趋势减少，而 Gemerek 和 Şarkışla 站的相应测量值增加，而 Tacin 岩溶泉的流量明显减少。同时，所有四个站点的温度参数都经历了类似的增加。因此，推断 Tacin 岩溶含水层流量减少的趋势源于在岩溶含水层南部观察到的降水趋势的减少。观察到 Pınarbaşı 和 Kayseri 站降水参数的变化趋势减少，而 Gemerek 和 Şarkışla 站的相应测量值增加，而 Tacin 岩溶泉的流量明显减少。同时，所有四个站点的温度参数都经历了类似的增加。因此，推断 Tacin 岩溶含水层流量减少的趋势源于在岩溶含水层南部观察到的降水趋势的减少。
