The resource and environmental quality evaluation is carried out in the Houhu farm enterprise of Jianghan Plain based on Arc/Info and the press-state-response model(PSR) which selects the soil integrated pollution index as a pressure index. The evaluation results can provide gist for reasonable land-utilization programming and environmental protection. To begin with

the factors affecting resource and environmental quality are decided by Delphi and PSR model and the weight of corresponding factors is calculated by AHP method. Then Arc/Info is used to establish spatial database by digitizing relational layers and developing buffer analysis. Furthermore

according to membership function of evaluation factors

original data of the specimens and the synthetic index method

environmental quality indexes of assessment units for cropland are calculated and the quality grades are divided by frequency distribution of synthetic index values. Finally

the map and data set of results in the Houhu farm enterprise are obtained automatically with Arc/Info. Results indicate that the environmental quality in this area is in medium and high side

the percentage of area in level 2 and 3 amounts to 47.27% and 35.83% respectively. By analyzing correlation between the soil contaminated status and environmental quality of cropland

the prominent plus correlation exists between both.
