根据立地条件和生物学特性 ,选择狗牙根 (Cynodondactylon)、百喜草 (Paspalumnotatum)和弯叶画眉草(Eragrostiscurvula)在深圳市赤红壤阳坡上单独或按不同比例混合喷建了 8种不同类型草坪 ,系统地研究了它们的生态、社会和经济效益 ,并采用层次分析 (AHP)结构模型对不同草坪进行综合评价 .筛选出了本立地类型的适宜草种和优化草种组合 .结果表明 :弯叶画眉草、百喜草是本立地类型建坪的理想草种 ;在立地条件差的陡坡上 ,混喷草坪的综合功能明显比单喷草坪好 .
According to the site conditions and biological characteristics, Cynodondactylon, Paspalumnotatum and Eragrostis curvula were selected and sprayed in different proportions on the slopes of red soil in Shenzhen. Eight different types The lawn was studied systematically and their ecological, social and economic benefits were systematically studied. The AHP structural model was used to evaluate the different turfgrass comprehensively, and the suitable grass species and optimized grass species combinations were selected. The results showed that: Curled-leaf thrush, Bahia grass is the ideal type of grassland type built Ping; poor site conditions on the steep slopes, spray lawn comprehensive function significantly better than single-spray lawn.
