Analysis of land use change features in the process of town development and its impact on ecological protection

Abstract

During the development of towns, there are constant changes in the way of land use. This paper took a town in Hebei province as an example, obtained its remote sensing data, analyzed the characteristics of land use changes and the impact on ecological protection in the area between 2013 and 2020, and calculated the degree of diversity, dynamic degree, and ecological index. The results showed that from 2013 to 2020, the area of the cultivated land in the town decreased by 423.33 km2, the area of the forest land decreased by 25.15 km2, but the area of the construction land increased by 454.743 km2; the degree of diversity was relatively stable, the overall dynamic degree was 0.24%, the fragmentation and separation degrees decreased; the cultivated and construction lands changed most. This study can provide a reference for the subsequent land use planning of this town.
