Study on Spatial Heterogeneity of Soil Properties in the Ecological Restoration Area of Yellow River Estuary
摘要
Abstract
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.关键词
