朝阳县土地利用空间格局及土壤侵蚀时空特征研究

Study on Spatial Pattern of Land Use and Spatiotemporal Characteristics of Soil Erosion in Chaoyang County

以朝阳县为例,研究2005—2020年区域土壤侵蚀时空变化特征及土地利用空间格局。结果表明,2005—2020年朝阳县各用地类型表现出明显变化特征,并以耕地和建设用地改变最显著;研究期间剧烈和极强烈侵蚀面积占比均有所减小,对不同用地类型耕地和草地主要为中度侵蚀。

Taking Chaoyang County as an example,this paper studies the spatial and temporal variation characteristics and spatial pattern of land use in the region from 2005—2020.The results showed that the land types in Chaoyang County showed obvious changes in 2005—2020,and the changes of cultivated land and construction land were the most significant.During the study period,the proportion of severe and extremely strong erosion area decreased,and the cultivated land and grassland of different land types were mainly moderately eroded.
