山茶属植物在长三角地区公园中应用的研究

以上海、金华、杭州、南京、苏州5个城市的85个公园绿地为主要研究对象,对山茶的应用密度、生长情况、应用品种、应用形式及植物配置等进行了调查和分析。初步结果表明:5个城市中,用作花篱、地被的山茶属(Cam ellia)植物应用密度为7.3 m2/hm2;而除地被及花篱应用形式之外的平均应用密度为11株/hm2,金华、苏州2个城市山茶的应用密度高于其他城市。5个城市的山茶生长情况以金华最好,南京最差。5个城市应用品种以中国传统品种为主,主要应用品种40余种。在应用形式上,山茶(C.japonica)多以群植方式出现,茶梅(C.sasanqua)多以地被和花篱的形式应用。各城市与山茶相配置的植物种类相似性很高,香樟(C innamomum camphora)、桂花(O smanthus fragrans)等植物种类在各城市中的出现频率均在20%以上。

Survey on Utilization of Plants in Camellia in Park of Yangtze River Delta

Eighty-five different landscapes in the park of Shanghai,Jinhua,Hangzhou,Nanjing and Suzhou were selected as the main studied objectives,the density,growth situation,varieties,designing and plant configuration of Camellia plants in their application were analyzed and evaluated.The preliminary results showed that the density of Camellia plants which were used as hedge and ground-cover was 7.3 m2/hm2,and the density of Camellia plants used as the other forms was 11 plant/hm2.The density of Camellia plants used in Jinhua and Suzhou city was relatively higher than that in other 3 cities.Camellia plants grew best in Jinhua and worst in Nanjing.Camellia cultivars used in 5 cities were mostly Chinese traditional cultivars,and there were about 40 cultivars in the investigated landscapes.For the application forms,C.japonica was mostly planted in group,Camellia sasanqua was mainly used as hedge or ground cover.The plant species which were matched with Camellia plants were highly similar in these 5 cities,the application frequency of Cinnamomum camphora and Osmanthus fragrans was all above 20%.
