Study On Cartography Of Chinese Soil Taxonomy Based On Geostatistics

The study on cartography of chinese soil taxonomy based on geostatistics by a case: eco-agriculture development area of Karamay. Main contents are presented as:(1)Basic classification unit system of Chinese Soil Taxonomy was established in eco-agriculture development area of Karamay.(2)The spatial variability characteristic of soil basic classification factors, soluble salts of surface and soil texture, was quantitatively described in Karamay development area of ecological agriculture. Based on the semi-variogram, the spatial distribution maps illustrating these properties are made by Ordinary Kriging.(3)After the analysis fundamental thought of cartography of Chinese Soil Taxonomy based on geostatistics, we put forward the basic methods of cartography and correlated problems.Based on drawing practise, the main conclusion as following:(1)On the basis of quantitative soil classification system, The soil automatism cartography adopted geostatistics was feasible, and it enable represent it's advantage especially in a large scale soil map, because it enable reflect exactly spatial variability and distribution characteristics of different soil in small scope.(2)As compared with conventional cartography, it enable decrease effectively sampling hits on the basis of assuring map precision, therefore it able to lessen a great deal of outdoor labor.(3)In the process of drawing, it realized automatism cartography, reduced subjectivity, heightened the speed and efficiency, and shortened mapping period.(4)The new cartography can renovate map agilely and expediently, accordingly soil drawing and classification synchronization.
