Abstract: With the help of remote sensing, geography information system, globe position system, the eco-logicaLimpacts of Bashang Eco-agriculture Project were monitored and evaluated.A qualitative description of the dynamics of the eco-environment was presented and the effects of Bashang Eco-agriculture Project on the cl-i mate, soiLwater, and other ecologicaLfactors were analyzed and evaluated.The results showed that the Bashang, after harnessed by Eco-agriculture Project, its system function had been strengthened up, and its structure tends to reach rationalization, acquire the obvious ecology beneficiaLresult.
