重庆市主城区综合性公园野生地被植物多样性分析与应用

Diversity Analysis and Application Investigation of Wild Ground Cover Plants in Comprehensive Parks in Urban Area of Chongqing

采用样地调查法,在重庆市主城区的21个综合性公园中设置128个详细观察样地,于2017年12月至2018年12月对公园内野生地被植物进行调查,分析常见的不同类型绿地空间下野生地被植物多样性与组成,从而分析其应用潜力。调查结果,共记录常见野生地被植物68种(含品种),分属31科57属。其中,广布野生地被植物(频度>10)重要值均在60%以上,野生地被植物种类集中分布在少数几种植物上,不同绿地空间类型结构下的野生地被植物多样性具有明显差异。经分析得出适于在重庆市各公园绿地不同空间类型下推广的野生地被植物品种,提出充分利用野生地被植物观赏特性,打造特色地被植物景观等建议。
