摘要
选取对沿海防护林体系建设有重要影响的生态防护价值、经济价值、社会价值三大类8个指标,从理论与实践相结合的角度,应用层次分析法对东南沿海基干林带后沿沙地防护林7种主要配置模式进行定性分析、定量评价.结果表明,在策略层各影响评价因子中,生态防护功能依然占首位,社会经济价值指标也占了很高的比重.各配置模式综合效益由大到小排序依次为:木麻黄与相思类混交(D1)>林果复合经营(D6)>木麻黄与多树种混交(D4)>木麻黄与桉树类混交(D2)>木麻黄与其他树种混交(D5)>木麻黄与灌木(D7)混交>麻黄与松树类混交(D3).根据所得结果还对各种配置模式在海岸带的梯度配置进行了分析.
Selecting 8 indicators belong to 3 categories namely ecological value, economic value and social value, in the line of integration of theory with practice, seven main arrangement modes were qualitatively analyzed and quantitatively evaluated applying analytic hierarchy process. The results imply that among all the factors in strategic layer, ecological function stands first, the weights of social and economic indexes are also quite high. The comprehensive effect of different arrangement modes decrease in the order of mixed forest of C. equisetifolia and Acacia, agroforestry of fruit trees and C. equisetifolia, mixed forest of C. equisetifolia and several other tree species, mixed forest of C. equisetifolia and eucalyptus, mixed forest of C. equisetifolia and other introduced tree species, mixed forest of C. equisetifolia and shrub, mixed forest of C. equisetifolia and pines. Based on the study results, the authors analyze the gradient arrangement of different modes at coastal zone.
