番禺地区引种种植红树林的研究

试图从理论和实践上解决6广东翻禺地区人们一直关心的“可否利用当地滩涂构建多用途的生态公益红树林体系”的问题，提出了在构建过程中的合理化建议，首先从多个理论角度论证在广东番禺地区引种种植红树林可以取得成功，然后通过在3个地点营造4个树种、遍布14.2km长的潮滩带、总面积达13.7hm^2的试验林进行实际检验，结果表明：实际试种检验结果与理论分析结论基本吻合，几个树种的保存率和生长情况与我国其它红树林主要分布地区相同树种的情况相当；适宜当地发展红树林的较佳树种为无瓣海桑、秋茄和木榄，适合它们生存的滩面高程分别为相对于海平面-0.8m,-0.74m和-0.43m以上。本文可作为当地有关政府部门发展红树林的一个决策依据，同时，也可为珠江三角洲沿岸抗议红树林提供参考。

Study on Constructing Mangrove Plantations in a large scale in Panyu, Guangdong Province

The paper aims at solving the problem from t he viewpoints of theory and practice, which the people living in Panyu, Guangdon g Province has been concerned with, i.e. "whether the vast extent of local tide lands can be used in constructing the ecological and public welfare mangrove pla ntation system or not?” and puts forward the rational suggestions in course of construction. First, it is proved from many theoretical points that constructing mangrove plantation in large scale can be won success in Panyu, and second, the conclusion is examined by a trial that are concerned with 4 mangrove species pl anted in 3 sites, 14.2 km long of dikes and 13.7 hectare of areas in total. The result shows that the practical examination corresponds to the theoretical concl usion basically. The survival rate and growth of above species are no less than that of the same species in main mangrove distributive areas of China. The bette r species for developing mangrove plantations in Panyu are Sonnerati a apetala Buch.-Ham, Kandelia candel (L.) D ruce and Bruguiera gymnorhiza (L.) Lam, and the altitude s of tideland suitable for their living are more than -0.8 m, -0.74 m and -0 .43 m separately comparing with the local mean sea level. The paper can be used as a decision-making guideline for constructing mangrove plantations in Panyu by th e local governments and organizations, and at same time, can be a reference for s preading mangroves in all areas of Pearl River Delta.
