摘要:
迄今为止,互花米草(Sporobolus alterniflorus (Loisel.) P.M.Peterson & Saarela)虽被列入外来入侵植物,但就其生态环境效应仍在学界颇有争议。以福建省泉州湾洛阳江河口湿地的互花米草种群为研究对象,分别于2017年6月(夏)、9月(秋)、12月(冬)和2018年3月(春)进行采样,测定互花米草在不同潮位的密度、株高、丛径、鲜重和干重等指标。研究结果表明:季节变化对互花米草的密度、株高、丛径、鲜重与干重差异均有显著影响(P<0.05)。三个潮区互花米草密度都呈现夏季>秋季>春季>冬季,且不同潮区四个季节之间互花米草密度差异显著;株高在四个季度中呈现秋季>夏季>冬季>春季,秋季显著高于其他季节;丛径随季节变化差异均显著,在夏季达到最大值;鲜重与干重在四个季度中均呈现秋季>夏季>冬季>春季,且鲜重随季节变化差异均显著,干重表现为秋季和夏季显著高于冬季和春季。
Abstract:
Heretofore,Sporobolus alterniflorus has been on the list of invasive plants,but it is still academically controversial about its ecological environment effect.The study concerned about the population of S.alterniflorus in the Luoyang River estuary wetland of Quanzhou Bay,Fujian Province,taking samples on June (Summer),September (Autumn),December (Winter) of 2017,and March (Spring) of 2018,to measure the difference of density,plant height,turf size,fresh weight,and dry weight of S.alterniflorus with change of tide levels.It was shown that seasonal changes had significant effects on the density,plant height,turf size,fresh weight and dry weight of S.alterniflorus (P<0.05).The densities of S. alterniflorus in the three tidal areas appeared as Summer>Autumn>Spring>Winter,what's more,the seasonal difference of density was obviously different in three different tidal areas.As for plant height,it appeared as Autumn>Summer>Winter>Spring,of which height in Autumn was evidently the top one.The turf size of S.alterniflorus also had great changes with seasonal variation in all three areas,reaching the maximum in Summer.Although fresh weight and dry weight showed as Autumn>Summer>Winter>Spring,fresh weight varied more significantly with seasons,while dry weight in Autumn and Summer was much heavier than in Winter and Spring.The conclusion of this study provide theoretical basis and reference for the protection of mangrove wetland in Quanzhou Bay and the treatment of S.alterniflorus.
