Small-scale Range Of Soil Organic Carbon Spatial Distribution And Reserve Estimates

It is estimated that the Earth's surface 1m soil organic carbon reserve 1500～2000Pg (1Pg=1015g), Atmospheric CO2 content of the two times, 0.1% of the soil carbon changes will result in atmospheric CO2 concentration circle occurred millionth changes. The domestic and foreign researchers studied in the small criterionregion unit the soil organic carbon storehouse achievement still notto see but are less regarding the arid area mountainous region soilspatial distribution and the reserves estimate research, therefore, carry out small-scale spatial variability of soil scope and estimated reserves of the research is of great significance.Based on the Urumqi River upstream of the experimental mountain valley soil, the profile of sampling points (1-100cm) and Preparation of the samples, a laboratory test samples SOCC (Soil organic carbon content). Data is divided into different depth of the five-storey. And tried to point SOCC profile limited to the statistical analysis, forecast and the space map, purpose is to a certain extent overcome profile point less intuitive and soil organic carbon see the spatial distribution trends, socc analysis of the spatial distribution.In this paper, the single factor to the Kriging interpolation and dual Cokrigring interpolation factors also had an in-depth and detailed analysis, by fitting the model to find the best theoretical model to predict the results of cross-validation and comparison of interpolation accuracy. And the forecast map on the basis of Continuous soil carbon content data stratified soil organic carbon estimated reserves of building soil organic carbon estimation model, In this paper, and using geologic statistical methods to study the scope of the small-scale soil organic carbon pool research, conducted some useful exploration.
