| Abstract: | Based on the indexes of landscape pattern in SheBiYa township from 1987 to 1997 the changes of spatial pattern of agricultural landscape were analyzed. The results show that with the time passing, the patchs of different landscape types increased sharply and mean patch area of each types decreased. The roles of dry farmland and grassland in this landscape became lower. but the roles of irrigated farmalnd and forest grew higher. In the meantime, the landscape diversity and evenness gradually increased, and the landscape was developing toward many dominances. |
