摘　　要：预测互花米草在沿海湿地潜在适生区分布是治理互花米草的有效途径。利用CLIMEX生态位模型对河北沿海湿地互花米草适生区进行分级预测。结果表明:河北互花米草主要分布在沧州黄骅和唐山丰南区,共计1.181 km^(2)。模型模拟结果显示互花米草易泛滥区面积有503.11 km^(2),分布在唐山市丰南区黑沿子镇及沧州贾家堡村,占河北省沿海湿地面积的29%;高适生区面积有494.31 km^(2),分布在南堡湿地、沧州滨海湿地及渤海新区,占河北省沿海湿地面积的28.5%;中适生区面积5161 km^(2),分布在乐亭县沿海、海兴湿地,占河北省沿海湿地面积的29.7%;低适生区面积164.31 km^(2),主要分布在秦皇岛沿海,占河北省沿海湿地面积的9.5%。针对互花米草适生区等级,采取分级治理策略,多地联控防止互花米草二次入侵。The strategic management of Spartina alterniflora involves predicting its potential suitable habitats in coastal wetlands.Based on CLIMEX model,we predicted suitable areas in Hebei coastal wetlands.Results showed that it thrived mainly in Huanghua,Cangzhou and Fengnan,covering a total area of 1.18 km^(2).CLIMEX showed that 96.7% of the coastal wetlands were suitable for the growth of S.alterniflora.Rampant regions covers 503.1 km^(2),which is distributed in Heiyanzi town,and Jiajiapu village,accounting for 29% of the total wetland area.Highly suitable areas is 494.3 km^(2),which is located in Nanpu wetland,Cangzhou coastal wetland and Bohai new area,accounting for 28.5% of the total area of the coastal wetlands in Hebei.Moderately suitable areas(516 km^(2)) are distributed in the coastal wetlands and Haixing wetlands in Laoting county,accounting for 29.7% of the total area of coastal wetlands in Hebei.The low-suitability area(164.3 km^(2)),mainly distributed in the coastal area of Qinhuangdao,accounting for 9.5% of the total coastal wetland area.Adopting a graded management strategy according to the level of habitat suitability for Spartina alterniflora,and multi-sites holistic approach is needed to prevent secondary invasion.
