摘　　要：定量化评估气象条件的影响可为红树林保护和修复提供重要决策依据。以广西北海典型沙生红树林为对象,利用北海红树林生态气象站观测数据、红树林植被指数和国家气象台站数据,研究影响红树林长势的关键气象因子、红树林小气候效应和气象指标阈值,建立红树林综合气象条件适宜度评估模型。结果表明,气温、降水量、相对湿度和风速为影响广西北海红树林生长的关键气象因子。红树林小气候效应明显,气象适宜度评估需对风速资料进行订正。采用生育期有效积温、累积降水量、相对湿度和风速作为评估指标,采用打分加权法,建立红树林综合气象条件适宜度评估模型,气象适宜度评估结果与红树林长势变化有较高的一致性。Quantitative evaluation on impact of meteorological condition plays an important role in protection and restoration of mangrove.Taking typical sandy mangrove as object,data from Beihai mangrove ecological meteorological station,mangrove vegetation index and data from national meteorological station were used to study key meteorological factors affecting mangrove growth,mangrove microclimate effect and meteorological index threshold,and model to evaluate suitability based on multiple meteorological conditions for mangrove growth was established.Results showed that temperature,rainfall,relative humidity and wind speed were key meteorological factors affecting growth of mangrove in Beihai,Guangxi.There was significant effect in mangrove microclimate,and wind speed data needed to be revised in meteorological suitability evaluation.Effective accumulative temprature,accumulative rainfall,relative humidity and wind speed in growth period were used as evaluation indexes,and scoring weighting method was used to establish suitability evaluation model based on multiple meteorological conditions for mangrove growth.Evaluation results showed good agreement with changes of mangrove growth.
