As China's economy develops and the governments at all levels attach great importance to water supply and sanitation. The problem of insufficient supply has gradually been eased; however, the problem of imbalance has not been obviously solved. The provincial statistical data in 2008 Health Statistics Yearbook shows that there is still a large gap between provinces in water supply and sanitation in...
High economic growth in Shandong has had huge implications for great water consumption and produced significant water pollutants. Saving index is introduced to analyze the evolution of the performance of water consumption, waste water discharges, COD (Chemical Oxygen Demand) and ammonia nitrogen emissions in Shandong over the past 12 years. The change of saving indexes represents Shandong's water...
The assessment system for the water conservation is of vital significance to construct a water conservation society that is one of the most important strategies in the harmous development of social economy and ecological environment. According to the idea of ecological water footprint available, the evaluation system is established for the assessment of water conservation society based on water quality...
Ecological security is the basis for the sustainable use of water resource. Take Jinan city as a case, ecological security of water resource is studied in this paper. Firstly, on the basis of the Pressure-State-Response (P-S-R) Model, a system of 23 indexes on ecological security of water resource is established. Then, analytical hierarchy process (AHP) is used to determine the index weights, and...
The increasing water demand directly results in the dwindling water supply in many cities of China. Water price plays an important role in the manage of urban water supply. The policy of laddered water price can reach the objective of water commodity pricing and establish the effective mechanisms with the core of water-saving, but it will face a practical problem due to for the lack of theoretical...
This study collecting the monitoring data for surface water quality and economic development data of Tianjin, and analyzed the water quality according to national water environmental quality standards between 1998 and 2008, it is found that Hai River and other main rivers were polluted badly except Yuqiao Reservior which is only drinking source water body. In the past two decade, economy of Tianjin...
Eco-hydrology regionalization plays an important role in releasing contradiction between water resources development and ecological environment protection. Based on the theory of self-organizing feature map (SOFM) artificial neural network, an eco-hydrology regionalization model is developed. In the model, several integrated indexes, which contain most original information, are extracted from a large...
Nighttime remote sensing imagery collected in 2000 and 2003 is exploited to estimate domestic water consumption (DWC) in China and the United States at province/state level. Sum light derived from satellite imagery has a statistically significant correlation with official DWC both in China and the United States. However, the differences of the patterns of settlement and DWC of the two countries lead...
