Effects of soil depth on above ground biomass in southeast of Qinghai Tibet Plateau

摘要：

　　Soil depth is one of the most important indicators of soil properties and vegetation.Obtaining accurate soil depth information is critical to improving the assessment of soil resources and analysis the relationship between soil depth and above ground biomass.In present study, the Ground Penetrating Radar (GPR) has been employed to determine soil depth.In addition, GIS and geostatistical techniques were used to map the spatial distribution of soil depth and Normalized Difference Vegetation Index (NDVI) data was utilized to forecast yield.Scatter plot of ruler-measured and GPR data showed that GPR is a suitable technique for determining soil depth.Spatial distribution maps revealed greater soil depth profiles in the northwestern and southeastern parts of the study area and soil depths in the study area were generally 30-40 cms.As well, the distribution of above ground biomass was consistent with soil depth.
