福建漳江口红树林生长与气象条件的关系

A correlation research between mangrove growth and meteorological Conditions of Zhangjiang Estuary in Yunxiao, Fujian province

漳江口是福建唯一的红树林国家级自然保护区,对生态环境意义重大,为了红树林合理布局的需要;采用农业气候分析方法,探讨漳江口红树林生长与气象条件的关系,分析温度、降水量、大风、日照等对红树林生长的利弊影响。结果表明,漳江口1￣3月上旬的极端低温和6月上旬￣8月中旬的极端高温都对红树林生长不利,5￣8月雨量充沛有利于红树林的生长,2￣3月阴雨寡照,不利于红树林生长发育,从台湾南部正面登陆云霄的台风和从台湾南部登陆粤东的影响云霄的超强台风,风力可达11级以上,对红树林产生较大损害;分析红树林生长与气象条件关系,提供专题气象服务,能为红树林合理布局、趋利避害提供科学的决策依据,为生态建设做出较大的贡献。

Zhangjiang Estuary national nature reserve, as the unique reserve of mangrove in Fujian province, is very important for eco-environment. For a logical management for mangrove distribution, relationship of mangrove growth and meteorological condition was analyzed by agro-meteorological method. The influence of meteorological factors such as temperature, precipitation, strong wind and sunshine on the growth of mangrove were also studied. The result showed that the abundant rainfall from May to August was advantageous to the growth of mangrove, while the extreme low temperature in the early month of January to March, the extreme high temperature from early June to middle August and the cloudy and drizzly conditions from February to March had an adverse effect. It also showed that both typhoon perpendicularly landing on Yunxiao and typhoon landing on Guangdong that effected Yunxiao, which may reach 11 levels, could cause damage to the growth of mangrove. Therefore, analyses of the relationship between mangrove and meteorological conditions, and special meteorological services can offer scientific suggestions, which can benefit the mangrove management, keep mangrove away from disasters and contribute to eco-environment.
