| 摘要: |
| 从2003年11月至2004年的9月对澳门路凼填海区湿地中的咸水湖和十字门水道的水质状况进行了6次调查。依照《海水水质标准》,除非离子氨和化学需氧量(COD)含量两水体都属IV类水质外,咸水湖的无机氮,磷酸盐均属于Ⅰ类水质,而十字门水道的无机氮属于IV类水质,磷酸盐属于Ⅲ类水质。以富营养化指数来评价,咸水湖与十字门水道两水体都处于富营养化范围,但十字门水道水体富营养化指数显著高于咸水湖。 |

| Abstract: |
| A study of brackish lake and Shizimen channel in the wetland of Lutan reclamation area of Macao was carried out from November 2003 to September 2004. According to the Sea Water Quality Standard of GB3097-1997, the levels of dissolved inorganic nitrogen and phosphate in the brackish lake were in the control of the StandardⅠ. However, the levels of dissolved inorganic nitrogen and phosphate in Shizimen channel were in the control of the Standard Ⅳ and Standard Ⅲ, respectively. Moreover, the levels of non-ion ammonia(NH3) and chemical oxygen demand(COD) in the two water bodies studied were in the control of Standard Ⅳ. Based on eutrophication indexes depicted by previous studied, both water bodies we examined and the extent of eutrophication in brackish lack was significantly better than that of Shizimen channel. |
