Abstract

Abstract: Taking Taocheng District, Hengshui City, Hebei Province as the study area, 91 Satellite Map Assistant was used to download the historical image data of GoogleEarth in 2014, 2017 and 2020, and the time points with clear imaging and less cloudiness were selected. Then the landscape pattern types in 2014, 2017 and 2020 were interpreted on the ArcGIS 10.3 platform. The landscape pattern indexes were calculated and analyzed by using Fragstas 4.2 software to study the temporal and spatial characteristics and the driving force of landscape pattern change in the study area. The results showed that, from 2014 to 2020, the construction land grew rapidly, and the farmland area showed a downward trend. From the analysis of the driving force of the landscape pattern, the influence of natural factors on the landscape pattern within a short span was very small. The rapid urbanization of Taocheng District had brought about rapid population growth, and the contradiction between man and land had become more prominent, which was also the main driving force that the increase in construction land was mainly due to the conversion of farmland. With the creation of high quality tourism development plans and forest cities, the landscape composition of waters and green land in Taocheng District had increased.
