摘　　要：调查了3口经网膜双层护坡改造后的河蟹养殖池塘在主养期的水环境参数。结果表明,改造后的河蟹池塘在5—9月间水质状况总体良好,其TN、TP、CODMn等指标均能达到《淡水池塘养殖水排放要求》(SC/T 9101—2007)一级排放的要求。提出网膜双层护坡值得在河蟹养殖池塘中推广改造。The water environmental parameters of three crab ponds improved by polyethylene film double layer slope were investigated during the major farming period.The results showed that the water quality of the modified crab pond was generally good from May to September,and the indexes of TN,TP and CODMn could meet the requirements of primary discharge of freshwater pond aquaculture water(SC/T 9101—2007).Therefore,the enhanced double layer treated slope is worth promoting and improving in the crab aquaculture pond.
