北京门头沟采石场废弃地造林树种生长状况调查

Adaptability analysis of planting species in the abandoned area of quarry in Mentougou District of Beijing

矿山废弃地生态恢复是环境建设的一项重要工作,为了探讨不同矿山废弃地植被恢复措施,作者对门头沟采石场不同植被恢复措施中实施6年后的乔木、灌木树种生长状况进行了调查,在建立树种适应性指数的基础上,对11种树种在门头沟采石场废弃地适应性进行了评价。结果表明:1)灌木类型适应性普遍高于乔木树种类型,各乔木、灌木适应性差异显著;2)乔木适应性表现为黄栌>银杏>油松>火炬>侧柏>桧柏+侧柏混交林>杜仲>国槐,灌木适应性表现为桃树>丁香>连翘。

The ecological restoration of abandoned mines is an important work to environment construction. In order to discuss vegetation restoration measures of abandoned mines, the growth adaptability of planting species were investigated after different vegetation restoration measures were implemented for six years on abandoned quarry in Mentougou. The adaptability of 11 kinds of planting species was evaluated based on the adaptability index. The vegetation investigation was implemented in the abandoned area of quarry in Mentougou, and the adaptability of 11 kinds of planting species was evaluated based on the adaptability index. The results showed： the adaptability of shrubs was better than that of arbors; the difference of the adaptability of the 11 kinds of planting species was significant. Adaptability of the 8 arbors were in the following order： Cotinus coggygria 〉 Ginkgo biloba 〉 Pinus tabulaeformis 〉 Rhus typhina 〉 Platycladas orientalis 〉 mixed forest of Sabina chinensis and Platycladus orientalis 〉 Eucommia ulmoides 〉 Sophora japonica, and that of shrubs were： Amygdalus persica 〉 Syringa pekinensis 〉 Forsythia suspensa.
