| 摘 要： | 基于大样本监测数据,从点位、湖区、全局3个层次,对梁子湖水质的季节变化和空间差异进行综合分析,发现梁子湖水质存在显著的季节差异和较大的空间差异:(1)季节上,夏、秋、冬季污染相对较重,春季污染相对较轻;夏、秋季主要污染指标为高锰酸盐指数(COD_(Mn)),冬季为总氮(TN);(2)空间上,东梁子湖和牛山湖污染相对较重,西梁子湖污染相对较轻;东梁子湖主要污染指标为COD_(Mn)、总磷(TP)和TN,牛山湖为COD_(Mn)、TN和氨氮,西梁子湖为COD_(Mn)和TN.研究结果有助于更好地了解梁子湖水质的时空变化特点,进而制定有针对性的保护措施和管理对策.

| Abstract: | Based on large sets of monitoring data, this paper analyzed the seasonal variation and spatial difference in four main parameters of water quality at Lake Liangzi, examining the water quality in three different spatial levels in individual sampling locations, subdivided lake areas and the entire lake. The major pollution parameters of CODMn, total nitrogen(TN) and total phosphorus(TP) were examined at the East Lake Liangzi, CODMn, TN and ammonia nitrogen at the Lake Niushan, CODMn and TN at the West Lake Liangzi. Results showed that there were significantly spatial and seasonal changes. Pollution was relatively serious in summer and fall as CODMn was high and in winter as TN was high, while the pollution was relatively light in spring. The results are helpful to better understand the spatial and seasonal patterns of water quality in Lake Liangzi and to find practical strategies for water quality protection and management. |
