上海市长宁区公园绿地群落调查分析与应用

针对上海市长宁区公园发展需求,选取了长宁区典型公园植物群落进行样地调查,结果表明公园植物群落类型主要包括:常绿针叶林、落叶针叶林、针阔混交林、常绿阔叶林、落叶阔叶林、常绿落叶阔叶混交林等共10类。调查发现公园绿地高频度植物分布较为集中,香樟和广玉兰的出现频度高达18.5%和15.7%,绿地植物群落多样性普遍较低;公园乔木以青壮年为主,高度集中分布在6.1~10.0m之间,径级多分布在10.1~25.0cm之间;绿地植物群落的景观空间类型较为丰富,其中半开敞空间类型数量最多,以林冠草坪型群落和林侧草坪型群落为主,占到调研群落的45%,便于居民休闲活动的开展;另外,公园植物群落配置较为单一,应注重利用乡土树种,构建接近自然的人工植物群落。
