Abstract: In this study, we focused on the influence of landscape change from 1950s to 1980s on the changes of suitable habitat and distribution of the Hainan Eld’s deer (Cervus eldi hainanus). Based on distribution data of the deer in 1950s and 1980s, we built two models of habitat distribution and a model of habitat distribution change. We further analyzed the main landscape factors influencing the suitable habitat distribution in the two periods, and evaluated the main landscape factors influencing the habitat distribution change from 1950s to 1980s. The results showed that the suitable habitat distribution of the deer had significant positive correlations with the forest cover and patch richness, but a significant negative correlation with the forest edge density in 1950s. However, in 1980s the suitable habitat distribution of the deer was negatively affected by the patch richness, but positively affected by the forest edge density. Road density also affected the suitable habitat distribution in the 1980s. The suitable habitat change was greatly affected by land use conversion from grassland to forest land and agricultural land, and from grassland and forest land to residential land. Moreover, the change of road density also made a contribution to the suitable habitat distribution. Our results confirmed that human disturbance greatly affected landscape change and resulted in the loss of deer habitat.
