Analysis on the Relation of Water Environment and Economic Development

The similarity in water environment variation course and economic development of the Taihu Lake riverbasin and Japan is analyzed and harnessing countermeasures are introduced. The close relation between economic development and water environment is analyzed. It is suggested that coordinated development policy of “Population-Resources-Environment-Economy” should be adopted. The research results demonstrate that water quality variation trend of the Taihu Lake riverbasin in the period of 1980s-the late 1990s was very similar the that of Japan in the period of 1960s-1980s, the rapid economic development of the Taihu Lake Riverbasin in the 1980s-1990s was similar to that of Japan rapid economic development period of 1960s.-1970s, the economic development level and water environment state of Japan in 1970 was very similar to that of the Taihu Lake Riverbasin in 1998,the economic development and water environment variation of the Taihu Lake riverbasin lags behind 20 plus years than that of Japan. We can infer the present and future situation of the Taihu Lake according to the history and present social-economic and water environment development situation of Japan.
