Describing System Of Soil Erosion Factor Spatial Variability

Applying the ArcGIS technology to analyzing the feature of soil erosion factor spatial variability, building the describing system of soil erosion factor spatial variability which bases on the ArcGIS platform.Basing on the basic analyzation method of soil erosion factor spatial variability, starting with the present solution and methods of researching about soil erosion factor, then did the systematically research about the methods of analyzing soil erosion factor spatial variability and the application fields of ArcGIS at home and abroad. The major concepts include: basic method about soil erosion factor research; the applying situation of ArcGIS in object spatial variability research; the real study reflect of spatial interpolation algorism which applied in spatial variability research.Combine the ArcGIS Engine technology and soil erosion factor analyzing method tightly, and basing on the carefully analyzing of business requirements of soil erosion factor spatial variability research, and then achieve the design of systems of representation of soil erosion factor spatial variability. It contains: soil erosion factor data management, spatial interpolation analyzation towards characteristic value, interpolation solution validating, each function module design, soil erosion factor spatial variability distribution map in east of sichuan and chongqing areas. The feature of system is that loading the space data quickly and clearly, then analyzing data with spatial interpolation method, accuracy verification and object's spatial variability representation, realize the efficient searching and analyzing function; assist soil erosion factor study, and develop the scientific and accuracy of soil erosion research.According to the previous solution, ArcGIS technology is friendly for soil erosion factor spatial variability analyze. This technology can systematically, quickly solve the various aspects problem which contained in soil erosion factor spatial variability research. It illustrates a good prospect of application. Developing soil erosion factor spatial variability system of representation by using the ArcGIS Engine bottom-level interface is advanced in technique, flexible in analysis, which will meet the relevant professional requirements. The functions which provided by ArcGIS Engine will have more potential in soil erosion factor spatial variability research. It will develop the efficiency of soil erosion prevent work, and make the planning, manage and decision process tends to be more scientific and digital.
