海岸防护林(海防林)是沿着海岸潮水线营造的带状林.我省的海岸防护林是东北防护林体系的组成部分.海岸防护林对减弱海风、保田增产有重要作用.据对金县海岸防护林调查,紧密结构林带的林后平均风速降低44%,春季平均气温提高1.5℃,0～20厘米土温增加1℃,林后水分蒸发降低32%,空气湿度增加5～10%.营造海岸防护林工作,应抓好土壤改良和适宜树种的选择. Coastal shelterbelt (Haiphong forest) is a belt-shaped forest along the tideline of the coast. Coastal shelterbelt of our province is an integral part of northeastern shelterbelt system. Coastal shelterbelt plays an important role in reducing the sea breeze and increasing yield of Baotian. , The average wind speed in the forest with compact structure belts decreased by 44%, the average temperature in spring increased by 1.5 ℃, the soil temperature increased by 1 ℃ in 0 ~ 20 cm, the forest evaporation reduced by 32% and the air humidity increased by 5 ~ 10%. , We should do a good job of soil improvement and selection of suitable tree species.
