Analysis of land-use changes in town development and ecological protection

During the development of the infrastructure of towns, there are constant changes in the way land is used. This paper, selecting a town in Hebei province as an example, obtained its remote sensing data, analysed the characteristics of land-use changes and the impact on ecological protection in the area between 2013 and 2020, and calculated its 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% and the fragmentation and separation degrees decreased. The cultivated and construction lands changed the most. This study can provide a reference for the subsequent land-use planning of this town.
