对佛山市5区的基本农田保护区养殖鱼塘水质抽样调查，并采用环境污染指数对水质状况进行评价。结果表明，养殖鱼塘水温和pH值均能达到鱼类正常生长要求，溶解氧较丰富，但水质普遍过肥。在5区20个调查点中，CODCr、NH4+-N和TP超标率分别为90%、30%、85%。5区养殖鱼塘水质的污染程度由高到低依次为禅城区、南海区、三水区、顺德区、高明区。全市养殖鱼塘的综合质量指数为1.44，水质整体上受到重度污染。TP的污染负荷分担率最高，其次是CODCr和NH4+-N。总体来说，佛山市基本农田保护区养殖鱼塘水体有机物污染十分突出，已出现富营养化。

To investigate the water quality of sampling in aquaculture ponds around the basic farmland protection areas in the five districts of Foshan city, and use the environmental pollution index to evaluate the condition of water quality. The results indicated that water temperature and pH of aquaculture ponds cound meet the requirements of fish normal growth,and dissolved oxygen was rich, but the water quality was over fertilized generally. In 20 investigation spots of the five districts, the content of CODCr, NH4+-N and TP exceeded 90 , 30 and 5 respectively. The pollution degrees of the water quality from high to low in aquaculture ponds were Chancheng district、Nanhai district、 Sanshui district、 Shunde district、 Gaoming district. The comprehensive quality index of aquaculture ponds was 1.44 in Foshan city, the water quality was polluted severly as a whole. The share rate of pollution load of TP was the highest, the second were CODCr and NH4+-N. On the whole, the pollution of organic matter was very prominent in the water quality of aquaculture ponds around the basic farmland protection areas in Foshan city that had been eutrophicated.
