本文调查、讨论分析了山南地区园林绿化的现状、特点及问题,提出了相应举措。本次共调查园林植物29科、60属、103种(含品种)。调查结果表明:1、乔木层、灌木层、草本层重要值最高的分别为白柳、金叶女贞、草地早熟禾,其重要值分别为53.220、27.980、74.205;2、山南地区的绿化植物中,应用最多的依次为蔷薇科、杨柳科、豆科和木犀科,分别为21、15、12、7种,分别占调查植物的20.39%、14.56%、11.65%、6.80%;3、从物种丰富度指数及多样性指数比较上看,该地区园林植物总体上多样性差,绿化结构单一性突出;4、该地区应用园林植物匮乏,地方特色不突出。
The current situation of gardening and greenspace building in Shannan Municipality was surveyed, the characteristics were analyzed, the related problems were discussed and some countermeasures were put forward correspondingly in this paper.
