山茶花是近代世界上闻名的园林绿化植物,世界各国兢相栽培以供观赏。近年来工业高度发达的国家特别象日本,由于工业畸形发展,造成了严重的环境污染,尤其是人口集中的工业城市环境污染更为严重。为此各工业发达国家均在研究如何保持城市清洁卫生,防止环境污染问题。据报导,在工厂烟尘浓、废气多、含硫化物特多,造成空气污染严重的地方,山茶花仍生长正常不受污染影响,证明山茶花有抗硫化物的功能。因此,今后在城市园林绿化中,山茶花将更有其发展前途。山茶花原产亚洲,尤以我国种类为多。目前世界各国栽培供园林观赏的有山茶花 Camellia japonica Linn.茶梅 Camellia sasanqua Thunb.云南山茶花 Camellia reticulata蔷薇茶花 Camellia rosaeflora HK.等种类,经过园艺家与育种家的努力,已培育出几百 Camellia is a modern world-renowned landscaping plants, the world Jing Jing cultivated for viewing. In recent years, the highly industrialized countries, like Japan, have caused serious environmental pollution due to industrial deformity. In particular, industrial cities with concentrated population have even more serious environmental pollution. To this end, all industrialized countries are studying how to maintain clean and hygienic cities and prevent environmental pollution. It has been reported that camellia still grows normally without pollution due to the thick soot, excessive exhaust gas and excess sulfides in the factories, resulting in serious air pollution. This shows that the camellia has the function of resisting sulfides. Therefore, in the future urban landscape, camellia will have more development prospects. Camellia native to Asia, especially in China as many species. Camellia japonica Linn. Camellia sasanqua Thunb. Camellia reticulata Camellia rosaeflora HK.
