摘要:
为提升太湖缓冲带林带的生态功能,减少入湖污染负荷,采用人工草坪替代林下杂草的方式,建立林草复合带.选取白三叶(Trifolium repens)、红花酢浆草(Oxalis corymbosa)、麦冬(Ophiopogon japonicus)、马蹄金(Dichondra erpens)和狗牙根(Cynodon dactylon)5种草坪, 在典型缓冲带林地按间距25 cm统一移栽种植.采用定位监测的方法分析草坪的生长特征与发展趋势.结果表明: 2011-2014年期间, 除狗牙根无法形成稳定的种群被杂草取代外, 其他4种草坪均能正常生长, 并形成优势种群;4种草坪中, 以麦冬和马蹄金生长状况最好, 生物量、盖度、均一性和青绿期综合指标等级较高, 其次是白三叶;红花酢浆草种群不稳定, 受水热的影响大.

Abstract:
In order to promote the ecology function of forest in buffer zone of Lake Taihu and decrease the pollution load of inflows the lake, forest-grass composite strips were established by substituting undergrowth weeds with artificial lawns.The growth feature and trend of five kinds of lawns, Trifolium repens, Oxalis corymbosa, Ophiopogon japonicus, Dichondra erpens and Cynodon dactylon planted in 25 cm under the forest in buffer zone were studied by positioning monitoring in this paper.The results are as follows: During 2011-2014, the most types of lawns could grow normally and formed a dominant population,except for Cynodon dactylon replaced by the weeds; Ophiopogon japonicus and Dichondra erpens were the best in terms of biomass, coverage, uniformity and green period, followed by the Trifolium repens, while Oxalis corymbosa population were unstable which affected by the hydrothermal conditions.
Key words:  Lawn  growth trend  buffer zones  under forest  Lake Taihu
