从防波效益分析湛江沿海红树林营造宽度

Analysis of Zhanjiang Seacoast Mangroves Structural Width for the Wave preventing Benefit

根据湛江沿海波浪分布情况 ,运用章家昌提出的防波林消波系数公式 ,以防波效益 80 %为目标 ,通过计算和综合分析得 :湛江沿岸营造红树林时 ,在潮差小 (约 2 m左右 )海区 ,营造宽度应在 80～1 2 0 m左右 ;在潮差大 (约 4 m左右 )海区 ,营造宽度应在 2 0 0～ 3 0 0 m左右。

According to the wave distributing situation along Zhanjiang seacoast, appling the wave attenuation coefficient formula established by zhang jiachang, through calculating and analysing with the goal of 80 percent of the wave preventing benefit, the reasonable structural width of growing mangroves along Zhanjiang seacoast is about 80 to 120 metres in the small tidal range (about two metres) sea area or about 200 to 300 metres in the large tidal range (about four metres) sea area.
