Strategic Measures

Recently Shiyang River Basin in China has been the area with greatest population density, highest utilization level of water resources, least per capita water resources, most striking conflict on water use and most serious ecological problems among inland river basins due to the overexploitation and out-of-order utilization of water resources with rapid social and economic development. The Key Control Plan of Shiyang River Basin was published in 2007, which raised the comprehensive control of Shiyang River Basin to the national level. On the basis of comparison analysis on the utilization of water resources and water ecological civilization construction since the key control of Shiyang River Basin, the strategic measures on the sustainable utilization of water resources are proposed.

Evaluation of regional water resources sustainable utilization provides a scientific basis for further water resources utilization and social economic sustainable development. How to use a scientific and rational evaluation index system to analyze the sustainable of water resources becomes particularly important .Based on the theory of sustainable development，This paper mainly studied on the case of Ningxia located in the western China. By using the method of fuzzy comprehensive evaluation and basing on the historical data of 5 years, The calculation of comprehensive evaluation matrix is established and the dynamic trend of Ningxia water resource sustainable utilization is evaluated for 2005-2009, and forecasted in 2015as well.

Abstract In this article, the comprehensive evaluation of water resource carrying capacity (for short WRCC) in Shiyang River Basin is the objective. Based on the comprehensive evaluation model of regional WRCC, the spatial and temporal change characteristics of the WRCC in Shiyang River Basin in 2007, 2011 and 2016 have been analyzed. Moreover, the influence elements of water resource carrying capacity in Shiyang River Basin are detected by the geographical detector. The results show that: (1) In terms of the spatial dimension, water resources in Shiyang River Basin are not in accordance with the distribution of social and economic development and population distribution, presenting a prominent contradiction between supply and demand of water resources; (2) in terms of the temporal dimension, the pressure on water resources in Shiyang River Basin has gradually increased, and the area of overload, light overload and serious overload has been augmented; (3) the geographical detector indicates that the influences of the water resources system and coordinating system factors are declining, and the influences of the social economy system and ecological factor are obviously increasing. The influences of the interaction with any two factors are stronger than that of a single factor, and the synergistic influences of two factors are aggravated.

Components Analysis

Data taken from the blood of 262 patients diagnosed for malabsorption, elective cholecystectomy, acute cholecystitis, infectious hepatitis, liver cirrhosis, or chronic renal disease were analyzed with three numerical taxonomy (NT) methods : cluster analysis, principal components analysis, and discriminant function analysis. Principal components analysis revealed discrete clusters of patients suffering from chronic renal disease, liver cirrhosis, and infectious hepatitis, which could be displayed by NT clustering as well as by plotting, but other disease groups were poorly defined. Sharper resolution of the same disease groups was attained by discriminant function analysis.
