以鄱阳湖保护区为研究对象,于2013年7月和8月采集样品21个,测试及分析样品中水化学组分,探讨其主要离子特征及空间分布特征。结果表明,河水及土壤水中的阳离子主要以Ca2+为主,阴离子以S O2-4、Cl-为主;井水阳离子以Ca2+为主,阴离子NO-3以为主,氮源是湖区水体的主要污染因子;鄱阳湖湿地保护区p H值变化范围为5.22~7.4 3,属微酸性至弱碱性。由测试结果得出,不合理的人类活动导致保护区水质下降,湿地生态系统遭受破坏。
Taking Poyang Lake reserve as the research object, 21 samples were collected in July and August 2013 to test and analyze the water chemistry components of the samples, and to explore their main ion characteristics and their spatial distribution characteristics. The results showed that the main cations in river water and soil water mainly consisted of Ca2 +, and the anions were mainly S O2-4 and Cl-. The main cations in well water were mainly Ca2 + and mainly anion NO-3. The nitrogen source was the main pollution of lake water The P value of Poyang Lake wetland reserve ranged from 5.22 to 7.43, which was slightly acidic to weakly alkaline. According to the test results, unreasonable human activities led to the decline of water quality in the nature reserve and the destruction of wetland ecosystems.
