Abstract-Rapid population growth and increased economic activity impose an urgent challenge on the sustainability of water environmental system in Beijing -Tianjin -Hebei (BTH) region. Water environmental system is a complex uncertain system under change which is of vulnerability. But water environmental system vulnerability research is relatively weak. In this study, we present a multifunctional hierarchy indicator system for the performance evaluation of water environmental vulnerability (WEV). This paper constructed the assessment index system of water environment system based on PSR model which contained 24 indicators considering social-economy conditions and situation of water resources. Weights were calculated by the method of analytic hierarchy process (AHP) and entropy, and fuzzy set pair analysis assessment method (FSPAAM) was applied to evaluate the degree of vulnerability in the Beijing -Tianjin -Hebei region.
Qaidam Basin in Qinghai Province has rich multiple complex resources with salt lakes as the core. These resources form a special condition for the development of green economy, having rare and particular nature. The Qaidam work is waiting to be done by scientific and technological innovation, with the guidance of low carbon, energy saving, comprehensive and recycling utilization. The development must be conducted on the following: energy(heat) storage materials of potassium, sodium, lithium and magnesium; modified materials of high purity magnesia, magnesium-based flame retardance, crystal whisker; alloy materials of magnesium-based light metals; building materials of magnesium cement; vinyl chloride series organic materials formed by combination of salt lake chloride ions with organic resources of coal and natural gas, etc. -all of salt lake featured materials industry system. Large-scale multiple utilization of renewable energy must be carried out such as solar and wind energy, and water power. Green industry system must be set up with new type green chlor-alkali industry and green energy source as the core. Through all above the comprehensive utilization level of salt lake resources can be improved, and the green sustainable development in Qaidam Basin can be realized.
ABSTRACT:The regional innovation system is a versatile, complex structure of large-scale system, whether its innovation ability and efficiency of the development of coordination is the key to determine how well the regional innovation system development. Therefore, further study of regional innovation capacity and regional innovation efficiency of coordination issues, for the effective integration of regional innovation resources, improving regional innovation capabilities are of great significance. With Anhui province as the object of empirical study, and selection of the materials, analyzing it's with using evaluation index system and coordination degree model. Finally, according to the analysis of the results and actual development make recommendations appropriate to enhance regional innovation capacity and regional innovation efficiency coordinated development.
