摘　　要：为了检验可降解生态覆盖垫在河滩地造林中抑制杂草生长的效果 ,分 3个处理 (有生态覆盖垫、无生态覆盖垫、空旷地对照 )对北京延庆县中德合作项目示范区的油松、刺槐、元宝枫、蒙古栎、侧柏和铺地柏等树种下的杂草盖度等级进行了调查。结果表明 :可降解生态垫的杂草抑制率超过 82 1% ;杂草生长越旺盛的林地 ,可降解生态垫的杂草抑制率越高 ;大苗和冠幅较大的树种 ,可降解生态垫抑制杂草的效果更为明显。To examine the effect of degradable ecomat on weed controlling in woodland on river-beach, weed coverage grades of different forests were investigated in the demonstration region of the Sina-Germany cooperation program in YanQing county. These forests were under three treatments in contrast: with ecomat, without ecomat and bare-land. The tree species were Pinus tabulaeformis, Robinia pseudoacacia, Acer truncatum, Quercus mongolica, Platycladus orientalis and Sabina procumbens. The results showed that the rate of weed controlling of degradable ecomat was over 82 1%; the rate was higher in forests where weeds were more vigorous; its effect on weed controlling was better for saplings and species with larger crown.
