Abstract

Abstract:

The aim of this study was to illustrate the effect of different types of land use on the physical and chemical properties of soil, as well as the influence of the ecological characteristics of chemical measurements in western Shanxi loess region, China. The study area included typical artificial mixed forests, Robinia pseudoacacia pure forests, economic forest lands, farmland, and grassland. Specifically, soil layers of 0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, 40-50 cm, and 50-60 cm were measured for soil bulk density, porosity, organic matter (TC), total nitrogen (TN), total phosphorus (TP) content, analysis of land use, soil physical and chemical properties, and the relationship between the ecological characteristics of chemical metrology to provide a basis for the rational use of land resources and ecological service functions. The bulk density (1.17 g·cm ^-3, 1.19 g·cm^-3, 1.20 g·cm^-3) of artificial mixed forest land, Robinia pseudoacacia pure forest, and economic forest land were significantly lower than that of cropland (1.31 g·cm ^-3) and wasteland (1.38 g·cm^-3). The contents of TC and TN in Robinia pseudoacacia pure forest were the highest (9.94 g·kg ^-1, 0.88 g·kg^-1, respectively), while those in the cropland were the lowest (7.26 g·kg^-1, 0.63 g·kg^-1, respectively), but TP showed no difference (P>0.05). Increased soil depth resulted in gradually increasing bulk density, gradually decreasing porosity, gradually decreasing TC and TN, and a relatively stable TP. The C:P (25.69, 20.51, 19.41) and N:P (2.23, 1.82, 1.58) of artificial mixed forest land, Robinia pseudoacinia pure forest land, and economic forest land, respectively, were higher than those of farmland (18.57, 1.62, respectively). The C:P and N:P decreased with increasing soil depth, but C:N remained stable. C:N was positively correlated with total porosity (P<0.05). C:P and N:P were significantly negatively correlated with soil bulk density (P<0.01), and significantly positively correlated with total porosity, non-capillary porosity, TC, TN, and C:N (P<0.05). The soil nutrient status of the forest land was significantly higher than that of the farmland, with the best effect found in the artificial mixed forest land. The conversion of cultivated land to forest improved soil quality. Thus, when returning cultivated land to forest and grassland, more attention should be paid to the collocation of tree species, instead of creating a single species forest over a large area.
