Abstract: Based on the GIS technology, the land of Xipo Village was partitioned into 39 soil ecological cells according to overlaying each special map. The potential productivity and practical productivity of the 39 soil ecological cells were calculated by the rectified PI formula and the input and output method. Results show that when the PI value of the land cells is higher, the practical productivity is higher, while the practical productivity is lower with the lower PI value. The correlation coefficient of potential productivity and practical productivity is 0.6563, which have a significant linear relationship. The results of the PI values present some rules, that is, the productivities of plain land are higher and those of sloping field are lower. On the plain land, the land cells that the PI value are higher are near by country residential area, and the land are flat and loamy. The land cells on the sloping field present that PI values in rich sunlight condition is higher than that in poor sunlight condition. As a whole, the land use of Xipo Village accord basically with natural and economical law, but some problems still exist and need to be reformed.
