The effect of land use on water quality is one of the most concerned problems hydro geologists in the world. On basis of this we put forward our own viewpoint and cognition. Analyzed the comprehensive summarize to the Land use change, retrospected the development history of the Land use change, and also analyzed and depicted the current research field. The exploitation and conservation of the Poyang...
Principal component analysis (PCA) were applied to assess surface water quality of the Songhuajiang River basin, China. Thirteen physical-chemical parameters in 25 stations were collected monthly during the period of 2008. Three factors were extracted by PCA, which explained 83.79% of the total variance. The first factor (PCA1) was positive correlated with permanganate index, BOD5, NH3-N, CODCr, TN,...
The increasing pollution load played a key role in the water quality deterioration and eutrophication of Lake Dianshan. The results of pollution surveys of 1985, 1995 and 2006 showed that the inputs of nitrogen and phosphorus from upper stream origin from Lake Taihu were up to 7565.0 t and 401.0 t in 2006, respectively, accounting for more than 90% of the sum; nitrogen input from non-point source...
Control unit of Liaohe River Basin and subordinate cities (counties or districts) was introduced. Industrial structure and distribution of Liaohe River Basin was described. Heavy industries have played an important role in the Liaohe River Basin's economic growth. COD and NH3-N emission of the main industries and their distribution in the Liaohe River Basin were analyzed. Green contribution of COD...
Urban rivers are closely related to the social and economic life. But urban rivers were polluted in different degrees. This paper explores Tianjin Outer Ring Sewage River and Jinhe River to conduct water quality analysis. The results showed that both rivers were polluted. Measures are suggested to improve the water quality. The paper can be used as a basic data for the pollution state and to provide...
Since the 1980s, Chinese water environment has got worse and worse, and water pollution extended from local pollution to total watershed pollution. From the Ninth Five-Year Plan, the government recognized the seriousness of water pollution, and put the core of the prevention and cure of water pollution in Three Rivers and Three Lakes, e.i. Huaihe River, Haihe River, Liaohe River, Taihu Lake, Chaohu...
Characterization of urban stormwater runoff was carried out in commercial, residential and cultural and educational zones during 2009 rainy season in Tianjin. The pH, DO, BOD5, COD, TOC, TSS, TN, TP, NH3-N, As, Pb, Zn, Cd, LAS and fecal coliforms in stormwater runoff were analyzed. The ranges of arithmetic mean concentration of COD, TSS, TN, LAS and fecal coliforms were 67-331 mg/L, 134-480 mg/L,...
Environmental capacity of the water basin was often used as the basis of total amount control of pollutants, which was concerned by environmental workers for a long time. However, with the governance of the on point source pollution, the non-point source (NPS) pollution drew people's close attention day by day. This article was selected to the main non-point source pollution of Dadu River of Luding...
Based on the monitoring results of water quality in Pinqing Lagoon in September 2008, the means of pH, salinity and dissolved oxygen (DO) outside of the lagoon is larger than those of inside. But the means of suspended material(SS), chemical oxygen demand(COD), biological control oxygen demand(BOD), total inorganic nitrogen(TIN), total inorganic phosphate(TIP), Oils, Zn, et al. are on the contrary,...
Various types of pollution source were evaluated in this paper through investigation and analysis in the watershed of Xiquanyan reservoir in recent years. Provide scientific and effective reference and technical support in preventing eutrophication of Xiquanyan reservoir and implementing protection and management decisions by government. Calculation and analysis showed the conclusions: Farmland non-point...
Take Hongze Lake of Jiangsu Province, China, as a Case, the components of lake water pollution were analyzed, based on the regular water quality monitoring data of 10 sampling points from 1990 to 2002 and the spatial data. By factor analysis and spatio-temporary correlation analysis etc, the spatio- temporary simulations to main lake water pollution components, including eutrophication, were carried...
