:运用层次分析法 (AnalyticHierarchyProcess ,简称AHP)对太行山石灰岩低山 区水土保持防护林体系林种结构、树种配置优化进行判断。结果表明 ,该区水土保持林以生态效益为主 ,兼顾经济效益和社会效益 ;以山坡水土保持林为主 ,多林种多树种结合 ,山坡水土保持林、梯田经济林、山顶防护林、沟头防护林、沟底防护林、沟边固岸林的比例分别为 2 8 6 %、18 2 %、17 5%、17 4 %、10 3%、8 0 %。在树种选择上应首先考虑侧柏、山合欢、黄连木、铅笔柏、五角枫、苦楝、花椒、黄栌、臭椿、柏树、香椿、荆条、山桃、柿、火炬树、山杏、紫穗槐、酸枣、杏、石榴等树种 ,以使防护林体系总体功能最优 ,效益最大。
: Analytic Hierarchy Process (AHP) was used to judge the structure of tree species and the optimal allocation of tree species in the lime-shelter-limestone low mountainous area in Taihang Mountain. The results showed that the main ecological benefits of the soil and water conservation forest in this area are both economic and social benefits; the slope soil and water conservation forest is the mainstay, the multi-species and multi-tree species combination, hillside soil and water conservation forest, terraced field economic forest, hilltop shelter forest and ditch head shelterbelts The proportions of ditch shelterbelts and ditches of fixed shore forests are respectively 2 8 6%, 18 2%, 17 5%, 17 4%, 10 3% and 80%. In the choice of species should first consider Platycladus orientalis, acacia, Pistacia, pencil Parker, Pentagon maple, Melia, pepper, yellow croaker, Ailanthus altissima, cypress, toon, Vitex, Peach, persimmon, torch tree, apricot, Amorpha, Jujube, apricot, pomegranate and other tree species, in order to make the overall function of shelterbelt optimal system, the most effective.
