| 用水质模糊识别评价法和对应分析法对东莞生生态园湿地水质进行了评价。结果表明，东莞生态
园综合水质优劣排序为：月湖- 中央水系> 大圳埔湿地> 燕岭湿地> 新建排渠> 南畲朗排渠> 下沙湿地> 大
圳埔排渠。整体上水质以劣Ⅴ类为主，其中人工排渠水质最差，其次是湿地系统，再次是开阔人工湖。东莞生
态园水体最为严重的污染物是总氮（TN）和大肠杆菌（E. coli），其水质呈现逐年变差趋势，尤其是开阔的人
工湖面区。切断污染源、削减污染物和提高水质自我净化能力是提高东莞生态园水质的迫切需求。模糊识别评
价法和对应分析法相结合可满足对湿地生态系统水质的综合分析的要求，为湿地水质管理提供依据。 |
| 英文摘要: |
| Fuzzy identification and correspondence analysis were used to evaluate the water quality in Dongguan
Eco-park wetland. The results showed that water quality was graded in the order：Yuehu-central water system >
Dazhenpu wetland > Yanling wetland > newly constructed drainage channel > Nanshelang drainage channel > Xiasha
wetland > Dazhenpu drainage channel. The water quality of eco-park was generally classified as below the Ⅴ grade.
Among different land use types，the water quality of drainage channels was the worst，followed by the wetland system，
and the central water system the least. The water was mostly polluted by total nitrogen and E. coli. The water quality was
turning worse year by year，especial for the central water system with open water. Countermeasures including cutting
off the pollution sources，reducing the pollutants and increasing the self-purifying capacity of water should be taken
immediately to improve the water quality. The combination of fuzzy identification and correspondence analysis can
be used as a useful integrated method for evaluating water quality，and provide information for wetland water quality
management. |
