Research On Water Environmental Vulnerability In KenLi Xian Shandong Province

In our country, the water shortage problem has already become the important factorrestricting economic development. In recent years, the country also puts forward the conceptof "ecological water conservancy", its core is the study of water pollution control, optimalallocation of water resources and sustainable use of the water pollution is one of the importantresearch topics, and water environmental vulnerability in the research field of the waterpollution is a unique research.At present, the water environmental vulnerability quantitative evaluation and analysis ofthe complexity of the reasons for its influence and other reasons, the domestic and foreignrelevant report limited, water environmental vulnerability analysis and its mapping is theinternational hydrological geology research hot spot and the frontier topic, also is theprevention and control of water environment pollution leading work, and the results can fornatural environment, social economic and other fields offer management an important basisfor decision-making. This paper examined the coastal area in the north of salt waterquantitative evaluation and analysis of vulnerability index system of regional water to theprotection of the environment and the rational development and utilization of provide certainreference. This paper KenLiXian water environment in shandong province as the researchobject, the main research contents and achievements are as follows:(1) Illustrated the modern of shallow groundwater vulnerability in theoreticalconnotation is sensitive to the upper aquifer pollution refers to a specific location on theorientation and possibility. Groundwater vulnerability can be divided into two kinds: one kindis the essence of vulnerability, need to consider local hydrological geological conditions, butthe nature of the pollutants and has nothing to do with pollution process. Another kind is thespecial vulnerability, need to consider the nature of the pollutants, and to recognize its andlocal hydrogeological conditions of relationship. (2) Considered by specific conditions in China’s coastal area such as local aquifer waterand groundwater salinity larger poor condition such as DRASTMICS constructs the model toevaluate the vulnerability of shallow groundwater by area, model of shallow groundwatervulnerability to the evaluation of the exploration, innovation, and puts forward with matchingcalculation method and evaluation standard.(3) This topic through the analysis of the causes of surface water vulnerability,constructing the surface water vulnerability evaluation index system, and put forward withmatching calculation method and evaluation standard. Evaluation model to cause both surfacewater environment of vulnerability, natural factors and human factors and load factors.(4) According to research that vulnerability evaluation model of surface water in thesurface water environment KenLiXian the case study, get the study area vulnerability surfacewater division, used GIS software rendering the vulnerability zoning maps, thriving in thetown of shengtuo streets and surface water environment...
