高校地表景观水水质现状评价

以高校典型人工景观湿地及景观水体为研究对象，根据GB3838—2002《地表水环境质量标准》及GBl2941—91《景观娱乐用水水质标准》进行单因子水质现状评价。评价结果表明：人工景观湿地水质劣于国家《景观娱乐用水水质标准》C类。从总磷（0．73mg／L）、氨氮（1．38mg／L）、叶绿素-a（0．085mg／L）说明水体属于中一富营养化程度，肉眼可见水体藻类大量繁殖，水体长期呈现深绿色及深棕色，感观较差。景观水体的水质整体较好，可达到GB3838—2002《地表水环境质量标准》Ⅳ类，但不能达到景观娱乐用水水质标准C类。针对这两种功能的景观水体污染现状提出治理建议。

Assessment of Current Landscape Water Quality in Universities

The typical artificial scenic wetland and the landscape water are studied in the paper. The water quality is assessed by the single factor method against the two standards. One is Surface Water Environmental Quality Standards （GB3838 -2002）, the other is Water Quality Standards for Landscape and Recreational Water （GB12941 -91 ）. The results show that the water quality of the artificial scenic wetland is worse than the Grade C of the latter national standards. The concentrations of total phosphorus, nitrogen ammonia and chlorophyll - a are respectively 0.73 rag/L, 1.38 mg/L and 0. 085 mg/L, so the water is medium -highly entrophicated. The growth of the algae is observed with naked eyes, and the water color is deep green or deep brown for a long time. It takes on an unpleasant look. Generally said, the water quality of the landscape water is relatively good, reaching Grade IV of the GB3838 -2002 standards but failing to reach the Grade C of the GB12941 -91 standards. This paper also proposes how to treat the two kinds of water body.
