摘　　要： 根据水道沿线周围地区的声环境质量现状,通过模式计算,对珠江三角洲陈村水道整治工程施工期和运行期间航道200m以内区域进行声环境影响预测与评价。施工期噪声在厂界以内基本符合标准,对周围环境造成的影响不大;营运期噪声对周围环境造成一定影响,噪声影响以林岳村最大,腰古农场最小,昼间等效声级最大为66.2dB(A),最小为63.5dB(A);夜间等效声级最大为58.8dB(A),最小为54dB(A),超标值昼间为5.8％～10.2％,夜间为8％～17.6％。 According to the status of the sound environmental quality on the both sides of Chencun steam in Zhujing Delta, the sound environmental impact in the areas from 0 to 200 meters of the dredging project of Chencun stream was predicted and assessed by the prediction model. During the building period, the equivalent sound level is basically conform to the national standard, and the environmental quality would not be impacted. During operation period, the environmental quality could be impacted in certain extent. The maximum noise impact is in Linyue village while the minimum noise impact is in Yaogu farm. The maximum day equivalent sound level is 66.3 dB(A), the minimum day equivalent sound level is 63.5 dB(A). The maximum night equivalent sound level is 58.8 dB(A), the minimum night equivalent sound level is 54 dB(A). The percentage of exceeding the national standard are 5.8%-10.2% in daytime, 8%-17.6% at night.
