摘要
2008年2月对广东省红树林遭受严重寒害的情况开展调查,并选取较有代表性的珠海淇澳岛红树林区作为样点进行详查。调查结果表明:①粤西红树林受寒害最重,粤中次之,粤东较轻;②受寒害严重的主要红树林造林树种为海桑类;③乡土树种的抗寒能力明显强于引进树种;④由寒潮引起的长时间持续低温是造成寒害的主要原因,红树林的受害程度还与生物学因素、生境因素相关。最后就灾后的红树林恢复提出了若干建议。
In February 2008, the serious cold damage of mangroves in Guangdong province were investigated. Qi＇ ao island of the Zhuhai city was selected as the sample plot for the detailed research. The investigation result indicates that： （1） the mangrove forests in western Guangdong suffers more than that in central Guangdong, while the eastern Guangdong suffers the least ; （2）Sonneratia species suffers the most serious damage; （3） the cold-resistance of native tree species is stronger than that of introduced tree species ; （4）continuous low-temperature for long time which is caused by cold wave is the main reason for cold damage. On the other hand, the extent of damage degree is closely relates with factors of biological and habitat. From analysis of this experience, some suggestions were proposed in this paper.
