摘要
针对福建沿海防护林树种单一化严重,林分结构简单,防护林生物多样化和生态系统稳定性差的现状,开展沙质海岸造林新树种选择研究,筛选适合于沿海特殊生境生长的优良种植材料。结果表明:厚荚相思、马占相思和大叶相思在沿海恶劣环境下具有较高的生产力和防护效果,而且能改善土壤理化性质,提高土壤肥力。以厚荚相思和马占相思构建防护林可形成持续稳定的生态防护屏障。
The experiment to select new tree species suitable to grow in coastal sandy soil was carried out based on the fact that the protective tree species were scares.The results showed that A.mangium,A.crassicarpa and A.auricualaeformis not only had high productivity and protective ability but also improved soil fertility.The protective forestry consisted of A.crassicarpa and A.auricualaeformis can form stable protective system.
