The effect of foreign investment on six pollutants such as industrial polluted water, and sulfur dioxide is investigated with the regression model. The result shows that there isn't significantly negative correlation between the FDI and pollution emission, which is contrary to the popular hypothesis so called pollution haven. The environmental effect of FDI notably varies among different regions,...
The study on groundwater vulnerability is an effective technical measure for rational development and protection of groundwater resource. In the paper, according to the hydrogeology conditions of the Lincang Basin in Yunnan Province, USEPA's DRASTIC method was applied to evaluate the groundwater vulnerability of this area with the consideration of depth to the water table, Net recharge, aquifer material,...
Assessment the changes of surface water quality in different times throughout one year is an important aspect for evaluating temporal variation of river pollution due to natural or anthropogenic input of point and non-point sources to water environment that is gradually deteriorating. In this paper, principal component analysis & factor analysis (PCA & FA) is conducted according to the average...
Based on the discharge standards of different industries, this paper determines the evaluation indexes of the status of water pollution in China. According to the discharge data of industrial water pollution of 31 provinces or regions in China, comparing some kinds of comprehensive evaluation methods used commonly for the status of water pollution, including the advantages and disadvantages, it adopts...
Identification of water quality conditions in a river system based on limited observations is an essential task for meeting the goals of environmental management. Various classification methods have been used for water quality estimation. However, a discrepancy frequently arises from the lack of a clear distinction between each water utilization mode, the uncertainty in the quality criteria employed...
Hohhot area as excessive exploitation of groundwater, the water level declining gradually, if not change this state of irrational exploitation may result in depletion of groundwater resources, groundwater drainage, land subsidence and other serious problems. In this paper, evaluation of the sustainability of groundwater resources in the administrative districts in Hohhot show that south area of Hohhot...
The contents and characteristics of ten heavy metals in surface sediments from Yangzonghai Lake in Yunnan, China were analyzed. Ecological risk index presented by Håkanson to assess the potential ecological risk of Yangzonghai Lake was utilized. The results showed that the average concentrations of titanium(Ti), manganese(Mn), zinc(Zn), vanadium(V), chromium(Cr), copper(Cu), nickel(Ni), cobalt(Co),...
Fuzzy mathematics method is used to evaluate the groundwater quality in Yang village. The groundwater quality of 18 villages belongs to V level water (GB/T14848-9 Quality standard for ground water) in the study area, where water pollution is very serious. Polluted area mainly includes the sandy soil region in northeast Yang village and east bank villages in western Beijing-Hangzhou Canal. Yinma village...
By the analysis of the present water supply and extraction, hydrogeological condition, groundwater quality and contaminant site etc. this paper illustrates that the present management and protection of the Dawu water site is not well, the chemical contaminant pollution is acute especially. Then, analyzes the present groundwater problem and pollution reasons, brings up an effective protection measures...
The domestic interior water body was monitored Based on an HJ-1 satellite multi-spectrum data. Chlorophyll a density is inverted from the empirical model based on the different area and different season. Suspension density inversion is based on the photobiology model of near-infrared waveband method. Based on chlorophyll a and the suspension density, the interior water body trophic level index is...
Based on the researches of water use efficiency in China and other countries, a water resource utilization efficiency assessment index system is proposed, which includes six kinds such as water use per 10,000 Yuan of GDP, removal variability of agriculture water resources utilization efficiency, per 10,000 Yuan of added industrial output value etc. By the cluster analysis of indicator data, it adopted...
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...
Twelve samples of surface sediment in Nanhu Lake, Wuhan city were collected and the concentrations of Organic Matter (OM), Total Nitrogen (TN), Total Phosphorus (TP), ammonia nitrogen (NH4+-N) and nitrate nitrogen (NO3--N) were determined; the average result were 6.58%, 3972, 1712, 897 and 20mg/kg separately. Cd, Hg, As, Cu, Pb, Cr and Zn were determined too; and the average value were 0.46, 0.140,...
The paper investigated the effects of irrigation of poultry waste water on soil fertility and biomass production of cabbage in accordance with the standard of Environmental Technical Terms for Green Food Production Area (NY/T391-2000). The results showed that irrigation of 46.88m3 per hectare every 10 days resulted in the highest production of biomass of cabbage as well best soil fertility index....
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...
According to Environmental Quality Standards for Surface Water in China (GB3838-2002), we used the 2006-2007 monitoring data to evaluate and characterize the water quality condition of a landscape river in Tianjin based on the comprehensive index methods such as Nemerow Index and single-factor assessment. The results are obtained as follows: (1) The water quality of M River belongs to class V water...
Due to the increasingly serious ecological degradation of offshore systems, the study on offshore water quality health has attracted more and more attention of the researchers and decision-makers. In this paper, water quality health assessment of offshore area in north branch of the Yangtze River Estuary from July 2006 to January 2007 was studied by fuzzy comprehensive evaluation method. The water...
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...
Groundwater pollution risk assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating groundwater pollution risk assessment by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of...
Based on ArcGIS and the feature analysis for the water environment and the source identification of water environmental health risks in a typical area in the western edge of Sichuan basin-Mingshan County in Ya'an City of Sichuan Province, China, this study tested the water quality of 41 drinking water sources, applied the health risk evaluation model recommended by USEPA (U.S. Environmental Protection...
