结果表明：徐州市水文地质单元岩溶地下水循环系统是一个复杂的循环系统，整个系统既有畅流型，又有汇流型和散流型。

The result shows that the karst water circulation system in Xuzhou is complicated with different flowing patterns of fluent flow , converging flow , and dispersing flow .

根据水均衡原理，分析了该区水文地质单元岩溶地下水循环系统，揭示了该区岩溶地下水在不同的自然地理及地质条件下的循环规律；

According to the principle of water balance , the karst water circulation system was analyzed , the circulation law under different geographical and geological conditions was studied .

虽然该区氨氮和亚硝态氮含量并不高，但是从岩溶区特殊的水文地质条件以及氮循环的角度来看，还是存在较大的污染风险。

Though ammonia and nitrite content were not high , but view from the special hydrogeological conditions as well as the nitrogen cycle , there is still a greater risk of contamination .

通过对徐州市岩溶地下水资源及补排关系的研究分析，揭示了该区岩溶地下水在不同的自然地理及地质条件下的循环规律。

Through the analysis of the resource and the relationship between recharge and discharge of the karst groundwater in Xuzhou City , the circulating discipline of the karst groundwater under different natural geographical and geological conditions was researched .
