摘要
从土壤物理性状和化学性状两方面探讨泥质海岸防护林改良土壤的功能。结果表明，防护林能减少土壤容重，增大孔隙，显著提高含水量，促进土壤形成良好的团粒结构且林分年龄越大结构性越好；同时，它也能提高土壤肥力，加快土壤熟化。
The paper deals with the physical and chemical improvement of soil properties of shelterforest in silting coastal areas.It was found that shelter forest can remarkably improve soil bulk density, poredty and moisture, promote the formation of soil structure naturally as sound age increases.The shelter foreSt can also improve fertility and speed mellowing of soil.Results show that shelter forest in silting coastal areas Plays a positive role in soil improvement.
