Investigation On The Present Situation Of The Ecological Environment And Studies On Countermeasurements Of The Sustainable Development In The Area Of Lake Weishan

Lake Weishan lies in the southwest of Shandong Province, which is the fifth largest fresh water lake in our country. This lake belongs to the continental monsoon climate area of temperate zone, whose waters area is about 1266km~2. The average total amount of water resource a year is 16.76*10~8m~3. Its climatic conditions are suitable for many kinds of aquatic and water plants ,which grow rapidly, reproduce quickly, and the natural resources are abundant .Lake Weishan have formed its own unique ecosystem in long historical succession advancement. This ecosystem takes self-sufficiency type as subject, maintaining benign cycle basically at the stage of long agricultural production. Since 80's of the 20th century, it caused the ecological environment of the lake region of Weishan obviously worsen because of all kinds of contaminative middle and small scale enterprises developing unboundedly, the masses blindly opening up wasteland wet, plundering resources, So only some water area reach to III lever water quality of the whole lake, most lake water are seriously polluted; The fish population and the quantity reduces rapidly, the fishing for fish age become small. The area of natural wetland falls sharply, the ecological function obviously drops; The lake district silts up seriously, the big area bog. It could not develop scientifically in the lake region, its production was in disorder, in addition, the coal was expanding constantly collapsing, the natural ecological environment was destroyed seriously, the ecological bearing capacity is dropping constantly in Lake Weishan.This research, on the investigated foundation of historical development, natural resources state and ecosystem current situation of Lake Weishan, combine the basic principle of the systematic theory and sustainable development theory with concrete practice of lake region ecological construction of Weishan, analyse the primary and secondary reason of ecology worsens of Lake Weishan scientifically, and predict the favorable and adverse effects of the project of east line of South-North Water Diversion after being...
