中文摘要为了研究黄河入海口生态恢复区不同植物群落下土壤属性的空间分异特征,垂直于海岸线由黄河岸边向海滩方向布设2条样带A—E、AA—EE,在每条样带的5个不同植物群落内采集土样,测定样品的碱解氮、有机质、含水率、可溶性盐和p H值。结果表明:研究区0~30 cm土壤中碱解氮、有机质、含水率、可溶性盐的平均含量和p H值分别为0.355 8mg/kg、0.330 4 g/kg、26.61%、0.926 2 g/kg、8.62;在水平方向上,土壤碱解氮和有机质含量以样带上香蒲—假苇拂子茅群落为中心向黄河岸边和近海光滩方向逐渐下降;土壤p H值、含水率及可溶性盐含量自黄河岸边向近海光滩方向呈波动式上升。此外...
英文摘要In order to study the spatial distribution characteristic of soil properties in different plants communities in ecological restoration area of the Yellow River Estuary,two transects of A to E and AA to EE from the Yellow River bank to a salt beach were selected and they were vertical with the coastline. Soil samples were collected in five different type of vegetation zones to determine the AN,TOC,SC,PH and moisture. The results show that,in the 0-30 cm soil layer,the average of AN,soil organic matter,moisture and SC are 0.355 8 mg / kg, 0.3304 g / kg,26.61% and 0. 9262 g / kg respectively,and the pH value is 8. 62. The soil available nitrogen and organic matter decrease gradually from the centering point C to the Yellow River bank and the salt beach,and the soil properties of pH,moisture and soluble salt increase from the Yellow River bank to salt beach horizontally. Moreover,the soil properties exhibit medium spatial variability except that PH has a weak variation. The soil samples were collected in vertical and horizontal ways. Each vertical sample included 0-10 cm,10-20 cm and 20-30 cm three samples. The method of Geostatistic was adopted to discover the spatial distribution characteristic of soil properties.
