| Abstract: | The changes on vegetation landscape pattern in the typical region of Y iluo River Valley show that the forest-covered area in the t ypical region has in creased,but the landscape fragmentation turns serious,the patch numbers increase fiercely,the average area of patches decreases and the shape of various patches becomes simple increasingly,the regional distribution of patch trends to unifor mity,and the distribution of patch trends to concentration. |
