摘要
为修复随州风电场建设导致的裸露边坡,保障风电场的绿色发展,依据生态修复的原则,结合植物的各种特性,进行生态修复植物的优选。首先根据现场调研的成果确定22种初筛植物,再利用层次分析法构造出植物优选层次图,然后从适应性、抗逆性、经济性、再生性以及景观性五个因素进行权重排序,再根据因素层权重得到目标权值,最终在此基础上筛选出适合本地区生态修复的优质植物。研究结果为适合修复该区域的九种优质植物:草本类植物为狗牙根、高羊茅、三叶草;灌木类植物为胡枝子、盐肤木、多花木兰;乔木类植物为构树、侧柏、松树,研究成果可为风电场区边坡的生态修复提供参考。在后续研究中可根据具体的地理环境条件,将理论与实践相结合,对植物进行更合理的权重赋值,对植被恢复效果做长期观测与研究。
To repair bare slope in wind farm area and guarantee the green development of wind farm,according to the principle of ecological restoration,and combined with various characteristics of plants,the optimization of ecological restoration plants is carried out.22 species of primary screening plants are first determined according to the results of field investigation,and then the hierarchical chart of plant optimization is constructed by using the analytic hierarchy process.Then,the weights of adaptability,resistance,economy,regeneration and landscape are sorted,and the target weights are obtained according to the weights of factor layers.Finally,the high-quality plants suitable for the ecological restoration of the region are selected on this basis.The results show that there are nine high quality plants suitable for restoration in this area:Cynodon dactylon,festuca arundinacea and Oxalis which belong to herbaceous plants;Lespedeza bicolor,Rhus chinensis and Magnolia multiflora which belong to shrub;Broussonetia papyrifera,platycladus orientalis and pines which belong to tree.The research results can provide reference for ecological restoration of slope in wind farm area.In the follow-up study,we can combine theory with practice according to the specific geographical environment conditions,and assign more reasonable weights to plants.Long-term observation and research are needed for the effect of vegetation restoration.
