In order to improve the low evaluation precision that the grey relational analysis method has been, the entropy theory was integrated to establish a new model. According to the variation of the index value, the coefficients of weight in the model are obtained from the utility value reflecting the information entropy of data, the subjective influence could(More)
Sanjiang Plain is the largest swamp area of freshwater and an important production base of commodity food grain in China. The groundwater resource plays an important role in the development of well-irrigation paddy. The groundwater system is a kind of complicated nonlinear system. Based on the power spectral analysis on groundwater depth series in Sanjiang(More)
By employing GIS data management and spatial analysis, established spatial database for groundwater and combined with dynamic balance method, accomplished 3D visualization of groundwater level, evaluated the spatial distribution of groundwater resources and the dynamic variation of groundwater level; The result shows that groundwater level continuously(More)
Based on fuzzy-matter-element analysis, combining the concept of Euclidean distance, the fuzzy-matter-element analysis method on the base of Euclidean distance is proposed. In the comprehensive evaluation on water resources sustainable utilization, the developing stages of every region are regarded as matter elements; and compound fuzzy-matter-element is(More)
Through applying projection pursuit evaluation (PPE) model based on real coding based accelerating genetic algorithm (RAGA) in the investment decision-making of water saving irrigation project, this study turns multi-dimension data into low dimension space. So the optimum projection direction can stand for the best influence to the collectivity. Thus, the(More)
