摘要
以江西省柘林水库水体为研究对象,对水库2008年枯水期、平水期及丰水期的水体进行监测分析和模糊评价,并对柘林水库作为南昌、九江两市备用水源地进行了可行性分析。结果表明,当取高锰酸盐指数(CODMn)、氨氮(NH3-N)、总磷(TP)等8项污染贡献率较大的水质指标进行模糊评价时,水库在3个时期水体水质均为Ⅰ级(GB 3838-2002),水体水质优良;柘林水库在水质条件、水量条件、地理位置、水库构造及地质条件上作为城市备用水源地都是合理可行的。
The qualities of water body of Zhelin Reservoir in wet period, water period and dry period in Jiangxi Province in 2008 were analyzed and evaluated by fuzzy assessment. The feasibility of Zhelin Reservoir as the backup water source for Nanchang City and Jiujiang City was analyzed. The results demonstrated that: water quality of Zhelin Reservoir was according with the permissible range of GB 3838-2002 first standard in 3 periods when 8 water quality items(like CODMn, NH3-N, TP, ere) in high pollution contribute rate were evaluated by fuzzy assessment. Taking Zhelin Reservoir as backup water source for city was reasonable considered from water quality condition, water quantity condition, geographical location, reservoir structure and geological condition.
