해풍은 육풍에 비해 더 높은 풍속, 염도, 습도를 가졌을 뿐 아니라 풍향의 전환도 빠른 특성을 갖고 있다. 수목의 초기 생장에 영향을 끼치는 주요한 인자 중 하나는 풍속이며, 일반적으로 초기 생장단계에서 수목의 생장률은 풍속이 감소될수록 증가하는 특성을 가진다. 따라서, 본 연구는 새만금 방조제에서 방풍시설을 설치함에 따라 수목의 생장과 해풍의 특성을 확인하기 위해 수행되었다. 본 연구에서는 폴리에틸렌재질의 방풍시설(개구율 40%)이 높이 3m, 길이 130m에 걸쳐 설치되었으며, 내외부에 1, 2, 3m 높이의 풍향풍속계를 5대 설치하여 2011년부터 2012년까지 1분 간격으로 수집하였다. 새만금 방조제 시험지의 풍향 빈도는 북풍이 26.8%, 북서풍 20.3%, 북동풍14.6% 순으로 나타났으며, 풍속은 높이별로 다르게 나타났다. 해송의 생장은 방풍시설 내부에서 자라는 경우가 외부에서 자라는 경우에 비해 수고 약 17%, 근원경 약 13% 높게 생장한 것으로 나타났다.
