Hydrochemical changes between 1991 and 2001 were assessed based on two synoptic stream surveys from the 820-km2 region of the Slavkov Forest and surrounding area, western Czech Republic. Marked declines of sulfate, nitrate, chloride, calcium and magnesium in surface waters were compared with other areas of Europe and North America recovering from acidification. Declines of sulfate concentration in the Slavkov Forest (-30 microeq L(-1) yr(-1)) were more dramatic than declines reported from other sites. However, these dramatic declines of strong acid anions did not generate a widespread increase of stream water pH in the Slavkov Forest. Only the most acidic streams experienced a slight increase of pH by 0.5 unit. An unexpected decline of stream water pH occurred in slightly alkaline streams.
基于对捷克共和国西部斯拉夫科夫森林及周边820平方公里区域进行的两次天气形势河流调查，评估了1991年至2001年期间的水化学变化。将地表水硫酸盐、硝酸盐、氯化物、钙和镁的显著下降与欧洲和北美其他从酸化中恢复的地区进行了比较。斯拉夫科夫森林中硫酸盐浓度的下降（-30微当量升⁻¹ 年⁻¹）比其他地点报告的下降更为显著。然而，这些强酸阴离子的显著下降并没有导致斯拉夫科夫森林中河水pH值普遍升高。只有酸性最强的溪流pH值略有上升0.5个单位。在微碱性溪流中，河水pH值出现了意外下降。
