To describe and register the evolutionary landscape pattern change of Kangding City over the past decades and explore the motivating factors via the remote sensing images of the yeas of 1990, 2000 and 2010, the authors have made an investigation and exploration of the indicative factors of the landscape pattern in accordance with the classic landscape scale mode by using the Fragstats 4.0 software. In doing so, we have also analyzed the dynamic changes in the transformation of the spatial centers of all the landscape types in the past 20 years. The results of our investigation and identification can be shown in the following main points: (1) The landscape pattern of the City has been mainly dominated by the forest land and the grassland landscapes, which are followed by the other types of landscape, such as the water bodies, the crop fields and the livestock breeding culture; (2) The entire shape of the landscape at the regional scale turned to be more simplified and dramatically promoted to a higher level during the period under study. Thus, it can be said that the landscape indexes of uniformity and diversity has been increased with the feature of homogeneity being decreased. (3) The areas of the cultural and forestland landscape has been increased with the areas of the cropland being shrunk from 1990 to 2010, though the other types of the landscape areas have seldom been found changed. Due to human interference, the landscape of cropland and the home-breeding husbandry landscape turn to be simplified and promoted to a higher level. (4) Truly speaking, little change and transformation have been found noticeably from the urban areas to the coordinative centers of the mixed landscapes during the decade from 1990 to 2000, whereas obvious changes can be observed from the decade between 2000 to 2010. For example, lots of cropland and grassland turn to be converted into forestland landscape with the grassland and forestland transformed into culture landscape. (5) Statistically speaking, the cultural landscape moved to the west by 0.058 degree while the cropland landscape moved to the north for 0.026 degree and a 0.033 degree shift to the west and then 0.026 degree to the south. The results of the principal component analysis demonstrate that the evolutionary change of the landscape pattern has mainly driven by the natural and anthropogenic factors, especially by the social and economic factors, political factors in addition to the urban population expansion on the dynamic changes of the landscape pattern of the city.
