广东番禺红树林造林研究

结合广东番禺红树林造林的现状，对影响红树林幼苗成活率和生长状况的因素进行初步分析，并据此提出提高造林保存率的措施等。影响红树林造林成活及生长的因素为：①水深：潮水越深，红树幼苗成活率越低，生长越差；②风浪：海面风浪越大，红树幼苗受干扰越大，成活和生长越差；③人为活动干扰为严重影响红树幼苗的成活和生长；④造林地的杂草会影响某些红树植物幼苗的光照条件；⑤海滩垃圾废物会挂断和压倒大量红树幼苗；⑥海滩石油污染会阻止红树胚轴的萌发；⑦幼苗种植时越粗壮，种植得越精细，则种植后生长越好。并提出提高造林成效的措施：①加强维护和管理：包括护理受损伤的红树幼苗，清除塑料袋等垃圾物，罅在红树幼苗区的捕捞活动，造林前清除杂草和固定某些红树植物幼苗；②补植受破坏的红树幼苗和扩大种植。

Researches on the Mangrove Plantation in Panyu,Guangdong

Combined with the conditions of mangrove plantation in Panyu of Guangdong,elementary analysis on the factors affecting the survival rate and growth condition of mangrove seedlings was carried out in the research,and accordingly the measures to increase the survival rate of seedlings were proposed.Factors affecting the survival and growth of mangrove seedlings are as following:① Depth of tide level:the deeper the tide level,the lower the survival rate and the worse the seedlings grew;② Wind and wave:the greater the wind and wave on the sea surface,the more severely the mangrove seedlings would be intervened and the worse they grew;③The human activities may greatly influence the survival and growth of mangrove seedlings;④ The herds of the plantation site may influence the lighting condition of the certain mangrove seedlings;⑤ The rubbish on the sea shore may break and crash down many mangrove seedlings;⑥The oil pollution on the sea shore may prevent the germination of mangrove propagule;⑦ The stronger the initiative seedlings and the more carefully the seedlings were planted,the better the growth.Following are the measures to improve the plantation effect:① To enhance the maintaining and management,including:maintaining the injured mangrove seedlings,getting rid of the rubbish such as plastic bags,prohibiting the fishing activities in the mangrove seedling area,getting rid of herbs before plantation and fixing certain mangrove seedlings;② To replant the ruined mangrove seedlings and extending the plantation.
