螃蟹对闽江河口互花米草湿地土壤活性养分变化的影响
|
摘要
为阐明螃蟹活动对湿地土壤活性养分含量变化的影响,对闽江河口湿地不同潮滩螃蟹干扰下的土壤DOC、MBC、NH_4~+-N、NO_3~--N、Fe及其价态含量特征进行测定和分析。结果表明:有螃蟹组土壤DOC和MBC含量分别为95.98,11.13mg/kg,对照组含量分别为106.99,7.54mg/kg,螃蟹组土壤DOC含量略低于对照组(P>0.05),螃蟹组土壤MBC含量高于对照组(P<0.05);两者含量最高值和最低值分别出现在夏季和冬季,且夏季显著高于其他季节(P<0.05)。螃蟹组土壤NH_4~+-N和土壤NO_3~--N含量分别为22.45,1.08mg/kg,对照组含量分别为23.65,1.44mg/kg,螃蟹组土壤NH_4~+-N含量低于对照组(P<0.05),螃蟹组土壤NO_3~--N含量低于对照组(P<0.05);不同季节,土壤NH_4~+-N和NO_3~--N含量存在显著差异(P<0.01)。螃蟹组土壤总铁含量略高于对照组(P>0.05);螃蟹组土壤Fe2+含量显著高于对照组(P<0.05);螃蟹组和对照组土壤Fe3+含量差异不明显(P>0.05)。不同季节,土壤总Fe、Fe~(2+)和Fe~(3+)含量存在显著差异(P<0.01)。
In order to clarify the effects of crab activities on the changes of available nutrients in wetland soils,soil DOC,MBC,NH_4~+-N,NO_3~--N,Fe and their valence contents under the interference of crabs from different tidal flats in Minjiang River estuarine wetlands were measured.The results showed that the average contents of DOC and MBC in soil were 95.98 and 11.13 mg/kg,respectively in the crab group and106.99 and 7.54 mg/kg in the control group,respectively(P<0.05).The content of MBC in soil of crab group was higher than that of control group(P<0.05).The highest and lowest values of the two contents appeared in summer and winter respectively,and were significantly higher in summer than in other seasons(P <0.05).The average values of soil NH_4~+-N and soil NO_3~--N in the crab group were 22.45 and 1.08 mg/kg,respectively,and those in the control group were 23.65 and 1.44 mg/kg.The content of NH_4~+-N in soil of crab group was lower than that of control group(P<0.05),while the content of NO_3~--N in soil of crab group was lower than that of control group(P<0.05).The contents of NH_4~+-N and NO_3~--N in soil were significantly different in different seasons(P<0.01).The soil total iron content in crab group was slightly higher than that in control group(P>0.05).The content of Fe~(2+) in soil of crab group was significantly higher than that in control group(P<0.05).There was no significant difference in soil Fe~(3+) content between crab group and control group(P>0.05).In different seasons,soil total Fe,Fe2+and Fe3+contents were significantly different(P<0.01).
