The Study On The Environmental Quality Evaluation Index System Of Ecosystem And Database Platform In Jilin Province

The ecological environment and the natural resource are material bases of the human's survival and development,And socio-economic stability and unity are the guarantee of the sustainable development of the socio-economic.Jilin province located at the middle of Northeast of china,South East is Tumen river,yalu river is the neighbor of North Korea.South is Liaoning province,west is Mongolia Autonomous Region, north is Heilongjiang province.The ecology status is very important,Its strategic position is self-evident.In recent years,under the integrated interference of global warming and human activities,China's ecological environment has been seriously damaged and it has a sign of deterioration,So effectively curb the trend of environmental degradation and restoration Protect the ecological environment become extremely urgent task.Therefore,this article carries on the exploration on the Jilin province ecological environment quality rating indicator system and the database platform's establishment,the major content of this paper is:1.The research background and development survey of ecological environment on Jilin province.The worsening ecological environment has awakened people's environmental consciousness,the developed country rose the environmental protection to the legal altitude.Our country ecological environment related research start is late,Jilin province is also quite weak in this aspect's research.Therefore,the use scientific method,establishes the perfect ecological environment evaluating indicator system to become the Jilin province ecological environment construction the urgent matter.2.The evaluation index system of ecological environment quality and evaluation criteriaOn the basis of expert advice,data query and actual investigation,screening 14 environmental index to construct the indicator system of ecological environment quality of Jilin province,mainly from four aspects including the climate,the vegetation,the soil and the hydrology.3.Database platform establishment of the evaluation of ecological environment quality of jilin province.The data owes lacking restricting the ecological environment construction seriously.the research foundation is quite weak in the region of ecological environment,Therefore,on the base of ecological environment quality researching and the condition in data message management.Uses the visualization programming tool Delphi to construct the operating system based on the Windows and SQL Server 2000 backstage database systems.Realizing the management on ecological environment essential through the informationization way.4.Functional module development of database platform For promotion the using value of ecological environment quality rating database,needs to design according to the region ecological environment research and to code realizes the environment quality evaluating indicator system module,because uses the modulation hierarchical structure and the Windows pattern design,the database system contact surface is friendly,simple easy to study,and moves steadily.
