摘要
南沙区位于珠三角的河网地带,全区整体防洪(潮)体系基础骨干框架已形成,但绝大部分海堤为传统海堤,需按照国家级自贸区的建设要求进一步进行生态化改造。根据南沙地区各水道的水文规律,按照设计洪潮水位、多年平均高潮位、多年平均低潮位等特征洪潮水位,以及区域动植物群落分布与海堤迎海侧堤岸的相对竖向关系进行生态结构分层,不同的分层采用不同的生态防护结构,形成适用于南沙地区的独特海堤生态防护结构体系。在不同的海堤建设条件和不同的水位条件下,可以组合运用,形成南沙独特的海堤生态风貌风格,冀可为以后该地区海堤生态化建设能提供借鉴。
Nansha District is located in the river network area of the Pearl River Delta,and the basic backbone framework of the overall flood control(tidal)system in the whole region has been formed,but most of the seawalls are traditional seawalls,which need to be further ecological transformation in accordance with the construction requirements of the national free trade zone.According to the hydrological law of each watercourse in Nansha area,the ecological structure is layered according to the design of flood tide water level,multi-year average high tide level,multi-year average low tide level and other characteristics,as well as the relative vertical relationship between the distribution of regional animal and plant communities and the seawall facing side of the seawall,and different ecological protection structures are adopted for different stratifications to form a unique seawall ecological protection structure system suitable for Nansha area.Under different seawall construction conditions and different water level conditions,it can be combined to form a unique seawall ecological style in Nansha,hoping to provide a little reference for the ecological construction of seawall in the region in the future.
