Karst rocky desertification is a kind of serious land degradation. And it is the third-largest ecological and environmental problem compared with China northwest desertification and soil erosion in loess plateau. Besides, fractal geometry theory is mainly used to explore the regularity, hierarchy and scale invariance hide in complex natural phenomena. And it is a new research angle that the fractal...
Topography is one of major factors influencing soil properties at the landscape scale, especially in hilly areas. Derived terrain attributes based on digital elevation models (DEMs) may be used for soil spatial distribution prediction. Accurate estimate of spatial variability of soil organic matter (SOM) is critical to evaluate soil quality as well as assess the C sequestration potential. However,...
When the development of an oil field comes into the middle and later stage, it is difficult to grasp the dynamic law due to continuous rising of water cut. A key to realize the optimal control of the whole process of oil development is to realize the accurate forecast of development indexes. This paper mainly investigates the application of data mining methods in development indexes forecast of an...
