Objectives
To establish a score system for environmental impact assessment by using Leopold matrix.
To evaluate local pollutant potential of urban and industrial area.

Literatures Review
Environmental impact assessment (EIA) EIA factors includes natural 、 social environment 、 pollutions 、
ecology 、 economic 、 culture…, it considered by effect area Tzilivakis et al. (2005) ; Larsen et al. (2010) ; Munier (2004).
EIA Methods in Cheng (2006) mentioned that Leopold matrix can show the effect for specific factors. (Whitlatch, 1976)
Da-tan of Guan-yin area and Jong-fu of Lu-ju area were polluted by cadmium contaminant by chemical factories (Cheng et al., 1994); it could move away by river flow (Hsu and Lo, 2000) .

Conclusion
CF, PSI, RPI and Waste disposal can be combined to assess local environmental impact.
Tsou-Ta urban area exhibits higher environmental impact; whereas Fu-gang urban area exhibits lower environmental impact.

Future Works
Finding more factors for the matrix in this study.
Using statistical analysis to infer weighting of factors.
Plotting time-space distribution graph and evaluate pollutant potential for urban and industrial areas.
