摘要
采用野外调查与室内分析相结合的方法,对泉州湾红树林群落及光滩不同潮位、距入海口不同位置土壤水分-物理性质进行研究。结果表明:0~30 cm土层土壤的多数水分物理性质受土层、潮位、距入海口位置影响不显著,高潮位土壤孔隙度及持水量大于低潮位,近入海口土壤容重大于其他断面,中间断面的持水量高于其他断面。土壤持水量随土层深度增加而下降;红树林土壤与光滩土壤差异显著(p<0.05),光滩土壤容重显著大于红树林土壤容重(p<0.05);红树林土壤总孔隙度、土壤最大持水量及毛管持水量显著大于光滩土壤(p<0.05)。
This study uses a combination of field investigation and indoor analysis to study the soil moisture-physical properties of mangrove community and mudflats at different tidal levels and different locations from the estuary.The results of this study show that:Most of the soil water physical properties in 0~30 cm soil layer were not significantly affected by soil layer,tidal level and distance from the estuary.The soil porosity and water holding capacity at high tide level are greater than those at low tide level.The soil capacity near the estuary is greater than that of other sections,and the water holding capacity of the middle section is higher than that of other sections.Soil water holding capacity decreased with the increase of soil depth.There was a significant difference between mangrove soil and bare land soil(p<0.05),and the bulk density of bare land soil was significantly higher than that of mangrove soil(p<0.05).The total porosity,maximum water holding capacity and capillary water holding capacity of mangrove soil were significantly higher than those of bare flat soil(p<0.05).
