In order to study the landscape pattern of Chishui Danxia Property of China Danxia World Natural Heritage, using GIS, ENVI and landscape pattern analysis software FRAGSTATS, we analyzed landscape pattern and its evolution law of the heritage sites and the buffer zone in the three key period of 2001, 2010 and 2016, revealed the characteristics of landscape pattern in the different development stages of Chishui Danxia Property of China Danxia World Natural Heritage, further discussed the influence factors of landscape pattern change. The results show that: (1) Since 2001, all kinds of landscape of the research area have been in the process of dynamic change, and forestland landscape is the dominant landscape of research area, which has occupied more than 80% of the research area, in the 16 years, the area of forestland, shrub and grass land, construction land, bare land and water body present the net increase, and the cultivated land area present the net decrease; (2) The landscape dynamic change degree in the 2001—2010 was larger, and the forestland landscape area ratio had increased by 6.98%, the cultivated land area ratio had decreased by 8.4% and the area had reduced by nearly a half, and 44% of the cultivated land area and 64.35% of the shrub and grass land area had been transferred to the forestland. The degree of landscape fragmentation had fallen sharply; (3) During 2010—2016, the landscape dynamic change degree was relatively small, and that the area ratio of forestland had decreased by 1.22%, the cultivated land area ratio had increased by 1%, and the construction area continued to increase; the transfer rate of construction land was highest, followed by bare land; the richness degree of landscape type had increased, the degree of landscape fragmentation had slightly risen; (4) In addition to the natural evolution of the ecological system, the policy of returning farmland to forest, urban construction, highway traffic construction are the main driving factors on landscape pattern change of research area, and tourism growth and development have relatively little impact on the landscape pattern.
