白坭水道航道整治工程环境影响研究

Study on influence of Baini waterway regulation project on environment

白坭水道航道整治工程拟通过疏浚、炸礁等航道整治工程措施来达到航道建设目的。通过数值模拟计算的方法,对施工环节的环境影响进行预测。结果表明:在充分落实各项环境保护对策与措施的前提下,整治工程疏浚、炸礁产生的水体中悬浮物浓度增加对白坭水道沿线水厂取水口取水安全不会产生不利影响,对水道沿线鱼类洄游通道、产卵场等生态环境影响可以接受。

Based on the waterway regulation measures such as dredging, reef explosion and so on, the target of constructing Baini waterway is achieved. Environmental effects of constructing are forecasted by means of mathematical model calculation. The predicted results show that the increasing of concentration suspended matter which is caused by regulation project has no disadvantage to the water intake security under the premise of implementation of environmental protection measures. Meanwhile, environmental impacts on fish migratory passages, spawning place are acceptable.
