Abstract:In order to clarify the spatial distribution characteristics of soil properties under different land use patterns, 133 topsoil samples (0-20 cm) were collected from Rongcheng County in Xiong'an New Area by grid method and random sampling method. The soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP), total potassium (TK), electrical conductivity (EC), salt salinity (SS), water content (WC), pH value, and soil mechanical composition under four different land use patterns as well as their spatial distribution features were analyzed by geostatistical methods and the tool of ArcGIS. The results showed that the soil in Rongcheng County belonged to light loam soil with neutral pH values. The contents of SOM, TN, TP and TK at the surface layer of soil were at the middle level. Under different land use patterns, except for the content of TK having no difference, the difference of other physical and chemical properties had reached very significant level (P<0.01). The pH value of soil (inland tidal flat > woodland > farmland > Park and green land); SOM content (farmland > Park and green land > woodland > inland tidal flat); TN content (farmland ≈ Park and green land > woodland > inland tidal flat); TP content (farmland > Park and green land > inland tidal flat > woodland); SS (inland tidal flat > farmland > woodland > Park and green land); WC (inland tidal flat > Park and green land > woodland > farmland); EC (inland tidal flat > farmland > Park and green land > woodland). Under different land use patterns, pH value of the soil had weak variability, SOM, TN, TP, TK, WC and EC had medium variability, and SS had high variability. The SOM, TN, and TP content of the soil in the study area was positively correlated with each other (P<0.01). The spatial distribution patterns of SOM, TN and TP in the study area were similar according to the method of spatial interpolation, showing a feature of less in the east and more in the west. WC, EC and SS also showed a very significantly positive correlation (P<0.01), and the spatial distribution was patchy. The results showed that all physical and chemical properties of surface soil in Rongcheng County had trend effect, and the change in the middle was more obvious than that in the north and south. The above results clarified the current situation and the spatial distribution pattern of soil physical and chemical properties, and will provide scientific support for land use and ecological construction in Xiong'an New Area.
