The landscape pattern of city in eight orientations was also analyzed using FRAGSTATS 3.3,and the landscape metrics selected were patch richness,shannon's diversity index,landscape shape index and mean patch size.The results show that: 1) the strongest growth preference of Taian city is in the ENE,where the spatial expansion intensity is 7.58%,and the weakest growth preference is in the NEN, where the intensity is 0.2% during the period from 1996 to 2004;2) the most depletion of cultivated land would occur when Taian city expands toward the ESE,where the quality weighting coefficient of cultivated land is 0.49;and when Taian city expands toward the NNW,where the quality weighting coefficient is 0.007, the depletion of cultivated land would be the least;3) the urban growth preferences are in conformity with the principle of the minimum cultivated land depletion;4) the diversity of landscape components is increasing with the enhancement of the urban growth preference,but landscape geometrical complexity and ecological fragmentation have different trends of change under different urban development modes.According to the principle of the minimum cultivated land depletion and the suitability of urban land use,we suggested that the urban growth preference should transfer from ENE to WSW and SES,and should promote city development compactly.This method provides a possible means to balance urban growth and farmland protection. %K Space development direction %K Urban growth preferences %K Depletion of cultivated land %K Octant %K Smart growth
