摘要
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 condition and biological characteristics, Bermudagrass (\%Cynodon dactylon\%), Bahiagrass(\%Paspalum notatum\%) and weeping lovegrass(\%Eragrostis curvula\%) were chosen to hydroseed 8 different type turf in south slopes of red soil in Shenzhen. The turfgrass seeds were sowed singly or mixedly according to different species and ratios. The ecological, social and economical effectiveness of the turf was studied systematically, and AHP structure model was used to assess different turfs. Suitable species and super combination under this site condition were selected. The results show: ① weeping lovegrass and Bahiagrass are the best species to establish turf under this site condition; ② On steep slope with bad condition, the comprehensive effectiveness of mixed turfgrass is much better than that of single turfgrass.
