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.

城镇发展过程中土地利用变化特征及其对生态保护的影响分析
在城镇发展过程中,土地利用方式不断发生变化。本文以河北省某镇为例,获取其遥感数据,分析该地区2013 - 2020年土地利用变化特征及其对生态保护的影响,并计算其多样性程度、动态性程度和生态指数。结果表明:2013 - 2020年,全镇耕地面积减少423.33 km2,林地面积减少25.15 km2,建设用地面积增加454.743 km2;多样性程度相对稳定,整体动态性为0.24%,破碎化、分离度下降;耕地和建设用地变化最大。本研究可为该城镇后续的土地利用规划提供参考。
