摘    要:为了筛选综合效益最佳的木麻黄+湿地松混交林模式,应用层次分析法,以蓄积量、生物量、风降率、风害率、土壤有机质质量分数和土壤速效养分质量分数为指标,对沙质海岸8年生的5种木麻黄+湿地松混交林模式(木麻黄与湿地松2:4带状混交、3:3带状混交、1:3行带混交、1:2行带混交及1:1行间混交)的生长效益、防护效益和地力维护效益状况分别进行研究,在此基础上对以上5种木麻黄+湿地松混交林模式综合效益进行评价。结果表明:5种木麻黄+湿地松混交林模式综合效益大小顺序为木麻黄与湿地松3:3带状混交模式〉2:4带状混交模式〉1:2行带混交模式〉1:1行间混交模式〉1:3行带混交模式。

Abstract:In order to screen the best mixed plantation model of Casuarina equisetifolia and Pinus elliottii, the analytic hierarchy process was applied to evaluate the benefits of growth, protection benefits and soil fertility of five models of mixed plantations of eight-year C. equisetifolia and P. elliottii in coastal sandy soil, namely 2:4 and 3:3 mixtures in strips, 1 : 3 and 1 : 2 mixtures in strips and rows, and 1 : 1 mixture in rows. Indexes of growing stock, stand biomass, wind-decreasing rate, wind-damage rate, soil organic matter and available fertilizer were measured. The benefit evaluation indicated that the comprehensive benefits of the five models ranked from high to low in the following order: 3:3 mixture in strips 〉 2:4 mixture in strips 〉 1:2 mixture in strips and rows 〉 1:1 mixture in rows 〉 1:3 mixture in strips and rows.
Keywords:sandy coast  Casuarina equisetifolia  Pinus elliottii  protection forest  mixed forest  analytichierarchy process  comprehensive evaluation
