摘要
以不同造林密度木麻黄防护林的抗风性及速生丰产特性为调查基础,运用多目标决策方法,对木麻黄防护林造林密度进行评价研究,结果表明:在木麻黄7种造林密度林分中,初植密度2500株/hm2的林分抗风能力和丰产性能最强,初植密度1667株/hm2的林分最速生,抗风能力和丰产性第二。综合评价指标以造林密度1667株/hm2的林分为最高,2500株/hm2的林分第二,建议滨海沙地木麻黄造林密度控制在1667～2500株/hm2。
Based on the investigation on wind-resistance,fast-growing and high-yield characters of different planting densities of casuarina equisetifolia protection forest was evaluated by means of polygonal decision.The results showed that among seven different planting densities of casuarina equisetifolia,the wind-resistance and high-yield characters were strongest in the stand with 2 500 plants/hm^2 while the stand with 1 667 plants/hm^2 grew fastest and its wind-resistance second.The comprehensive evaluation index of the stand with 1 667 plants/hm^2 was highest and that of the stand with 2 500 plants/hm^2 was second.The suitable planting density of casuarina equisetifolia in sandy soil should be from 1 667 plants/hm^2 to 2 500 plants/hm^2
