| Abstract: |
| The digital elevation model（DEM）， soil data， land use data， GIS and mathematical models were used to evaluate the suitability of Yongshang town precocious pear land. The results showed that the suitable areas for precocious pear was 435.28hm 2 ， occupied 25.21% of total areas in Yongshang town. Analysis of the spatial distri- bution of Land for planting precocious pear by GIS and suitability cost surface model showed that the scale of plant- ing was in line with the requirements（333.33hm 2 ）of multi-objective model in agricultural planning， when the max width expanded to 56m. |
