- Abstract:
- Understanding the soil nutrient condition in reclaimed village will make a difference on improving soil quality and soil fertility in the course of land reclamation. A reclaimed village in Zezhou County of Shanxi Province was selected as the study area, the spatial variability of soil nutrients in reclaimed village was comprehensively analyzed by a combination of geostatistics with a geographic information system (GIS). The results were shown as follows. (1) The variation coefficient of 4 soil nutrients ranged from 19.78% to 29.45%, which indicated the variation degree of soil nutrients was relatively small. The semi-variance models of 4 soli nutrients were in line with the Gaussian model. (2) The ranges of organic matter (OM), total nitrogen (TN), available K (AK) and available P (AP) were 59.70, 54.47, 55.59 and 66.87 m, respectively, and the nugget factors were 74.2%, 74.9%, 69.1% and 76.5%, respectively, which suggested that the soil nutrients had medium spatial correlation. (3) The maximum values of OM, TN and AP were concentrated in two parts namely northeast and southwest near central regions, and the distribution of AP was descending from the central to the peripheral areas. (4) The spatial distribution pattern of soil nutrients was formed under the influence of the terrain change, human activity and some random factors. Mastering the distribution of village soli nutrients will provide the basis for enhancing quality of arable land after reclamation, precise management of soil nutrients and fertilization decision in villages of coal base.
