ABSTRACT
In this paper, Huailai County in China’s Hebei Provice is considered an example for analyzing the characteristics of landscape patterns with three remote sensing datasets in 1995, 2005, and 2015. The land use change and landscape pattern of the study area were analyzed and it was found that from 1995 to 2015, the area with the largest change of land use type was cultivated land and construction land. Results show an increasing landscape fragmentation in this area. Meanwhile, the connectivity presents a downward trend. In combination with the distribution of different landscape type patterns on the terrain niche and the functions of ecosystem services, a minimum cumulative resistance model was used to construct the landscape components of ecological sources, ecological corridors, and ecological nodes. The obtained dIIC and dPC show that river confluences and the surrounding area of the reservoirs are most important for landscape connectivity. Based on the above research, maintenance areas, restoration areas, enhancement areas, and protection areas of the landscape are divided, which will be useful for optimizing the ecological landscape.
