深圳龙岗河干流碧道建设对环境的影响及保护措施

Environmental Impact and Protection Measuresof Bidao on the Mainstream of Longgang River in Shenzhen

水环境治理和保护越来越受到重视,碧道建设不仅可以治理水环境,而且能够起到景观与游憩的作用,碧道工程建设期和运行期会对自然环境产生一定的影响。例如,施工时容易引起局部水体悬浮物的增加,导致施工区域水质产生较高的浊度,饮用水水质下降;扬尘污染施工现场的大气环境;施工机械噪声影响周边居民生产以及生活;施工产生大量固体废弃物等。以深圳市龙岗河干流为例,分析了碧道建设对环境的影响,明确了对生态环境、水环境、声环境、大气环境以及周边交通的影响。提出有效措施以预防和减少由于建设施工和运营所产生的大气、水、噪声及固体废弃物等污染,最大限度地保护生态环境。对碧道工程建设具有推广意义。

More and more attention has been paid to water environment treatment and protection.Bidao construction can not only control the water environment,but also play the role of landscape and recreation.The construction and operation period of Bidao project will have a certain impact on the natural environment.For example,during construction,it is easy to cause the increase of suspended solids in local water bodies,resulting in high turbidity of water quality in the construction area and decline of drinking water quality;Fugitive dust pollutes the atmospheric environment of the construction site;The noise of construction machinery affects the production and life of surrounding residents;A large number of solid wastes are generated during construction.Taking the main stream of Longgang River in Shenzhen as an example,this paper analyzes the impact of Bidao construction on the environment,and defines the impact on the ecological environment,water environment,acoustic environment,atmospheric environment and surrounding traffic.Put forward effective measures to prevent and reduce air,water,noise and solid waste pollution caused by construction and operation,and protect the ecological environment to the greatest extent.It is of great significance to promote the construction of Bidao project.
