摘　　要：针对当前沿海沙质海岸造林树种单一,防护林林分结构简单、生物多样性差和生态稳定性不强的现状,于1996年在福建惠安县赤湖林场开展木麻黄马占相思混交林和木麻黄纯林对比试验。研究结果表明:混交林中木麻黄保存率、树高、胸径生长量均大大超过木麻黄纯林;混交林防护效益明显大于木麻黄纯林;混交林林地土壤肥力高,改土效果显著。In order to change the simple situation of plantation species in the costal area and ensure the steadiness of ecological system of protective forestry,the experiment of mixed forest of Casuarina and Acacia mangium compared with the pure forest of Casuarina was carried out in 1996.The results showed that the preserved rate,the growth increment of height and diameter of mixed forest were superior to the pure of Casuarina;the protective benefits of mixed forest were obviously larger than that of the pure of Casuarina;the soil fertility in the mixed forest was apparently improved.
