摘要
济南奥体中心的建设使得原地区的地表结构、风貌特征及生态环境发生改变,导致山体和生态景观系统破碎化,对区域环境景观、水土保持、生态稳定性产生了极大的负面影响。从喷播造林种类的初始出苗率、种子发芽深度、成苗率、喷播种生长情况、盖度以及自然种侵入情况等6种指标对该项目生态恢复的植被响应过程进行研究。经过3a的群落演替过程,群落从最初以草本植物狗牙根、黑麦草为主,演进到2011年形成了草本植物以野黄菊为优势种,木本植物以刺槐为优势种的乔、灌、草、花复层植物群落,坡面植物组成由10种变为16种,植被总盖度达到了99.0%。
The construction of Jinan Olympic Sports Centre has caused great changes in original site from the aspects of surface structure,geomorphological style,and the ecological environment,resulting in the fragmentations of the mountain and ecological landscape.Negative impacts have been formed on the regional environmental landscape,soil and water conservation,and ecological stability.This paper attempted to analyze vegetation response process of ecological restoration by six kinds of indicators,such as initial rate of emergence,seeding species,germination depth,rate of seedling,spray seeding growth situation,covering,and natural species invading situation.After three years of community succession process,communities have evolved from initial bermudagrass and ryegrass-based herb-dominated communities into the wild Chrysanthemum indicum dominated specie of herb,and the locust tree dominated specie of woody plants into tree,shrub,grass and flowers stratified plant communities.Composition of slope plants increased from 10 to 16 species,and the total vegetation coverage reached 99.0%.
