Based on the existing urban forest landscape of Shenyang,four landscape pattern gradients were simulated,and one existing landscape pattern gradient in accordance with the trend of these gradients was selected.By analyzing the responses of 28 landscape metrics for landscape fragmentation and patch shape complexity to various landscape pattern gradients,preference landscape metrics were selected for describing the degree of the two landscape pattern characteristics.The results showed that patch density(PD) and mean patch area(AREA_MN) regularly responded to the change of landscape fragmentation.The increase of landscape fragmentation resulted in an increase of PD value while a decrease of AREA_MN value.Patch shape complexity of area weighted mean perimeter area ratio(PARA_AM) coincided with the gradients of landscape pattern.PARA_AM value increased with increasing patch shape complexity,which precisely characterized the degree of patch shape complexity.
