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,...
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...
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...
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...
According to the actual conditions of the plain area of Jilin Province, and based on the DRASTIC index system, the Vector Drawing Function in GIS Software is applied to draw single index figures. Then different figures form the assessment cells by the Module of Special Superposition Analysis. The attributive database of GIS is applied to evaluate the antipollution capability of groundwater in the...
Correct evaluation water resources sustainability of a city or an area is one of the most important way to understand the development potential of it. The paper introduced the concept of social adaptive ability, established a social index system and evaluation method of water resources scarcity, and took Tianjin as a case to evaluate water resources sustainability of it from 1998 to 2006. The results...
In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems, the author establishes subsystem hierarchy...
In this paper, measured values of annual indexes were directly utilized to assessment. By using projection, we make integrated assessment of environmental quality in Guangzhou City from 2003 to 2007. The order of annual environmental quality is obtained. The results show that the environmental quality in Guangzhou is worrying.
