地下水质监测——水文地质系统污染预防的有效方法

地下水质监测在地下水保护和质量守恒方面起着重要作用。在捷克斯洛伐克开展的国家、区域和特殊场地监测项目主要涉及地下水质和区域污染扩散问题相关背景资料的收集。安装有数据自动收集系统的试验监测站，优化了监测方法、监测网的设计和采样技术。捷克斯洛伐克的地下水质监测为密集耕作区相关决策与政策的制定提供了依据。对捷克斯洛伐克多个地区的浅层脆弱性含水层的时空变化进行了评价，从而为土地利用综合规划和地下水保护管理提供依据。     

波希米亚高地

波希米亚高地位于今捷克斯洛伐克的波希米亚地区．森林．面积大约158．000平方公里．海拔1．602米。西南部是波希米亚森林．由奥赫热河上游河谷至奥地利境内的多瑙河河谷．则呈西北-东南分布．海拔3．500英尺．主要为针叶林和落叶林。     

维也纳：音乐之都

Teleconnections of inter-annual streamflow fluctuation in Slovakia with Arctic Oscillation,North Atlantic Oscillation,Southern Oscillation,and Quasi-Biennial Oscillation phenomena

The aim of the paper is to analyze a possible teleconnection of Quasi-Biennial Oscillation （QBO）, Southern Oscillation （SO）, North Atlantic Oscillation （NAO）, and Arctic Oscillation （AO） phenomena with longterm streamflow fluctuation of the Bela River （1895-2004） and Cierny Hron River （1931-2004） （central Slovakia）. Homogeneity, long-term trends, as well as inter-annual dry and wet cycles were analyzed for the entire 1895-2004 time series of the Bela River and for the 1931-2004 time series of the Cierny Hron River. Inter-annual fluctuation of the wet and dry periods was identified using spectral analysis. The most significant period is that of 3.6 years. Other significant periods are those of 2.35 years, 13.5 years, and 21 years. Since these periods were found in other rivers of the world, as well as in SO, NAO, and AO phenomena, they can be considered as relating to the general regularity of the Earth.
