摘　　要：为更加深入了解城镇化背景下县域土地利用类型和景观格局变化,研究以"3S"技术为手段,以湖南安仁为案例,分别对2006年和2016年土地利用类型进行解译,分析此期间土地利用类型变化,并分别计算各年份多种景观指数﹒研究结果表明:林地和耕地一直是安仁县的主要土地利用类型,研究期间,耕地面积有所增加,林地面积有所减少;建筑物面积有所增减,不同土地利用类型主要向耕地转化;景观破碎化程度在降低,景观多样性增加,斑块分布更加均匀稳定﹒研究认为城镇化进程给县域森林景观保护带来了很大的压力,在城镇化进程中,坚持生态原则,实施生态规划,对于景观保护和景观格局稳定具有重要作用﹒本研究能够为县域尺度生态规划提供参考,对县域景观保护具有重要意义﹒In order to understand the changes of land use and landscape patterns in the county scale under the background of urbanization, this research takes Anren, Hunan Province as an example to analyze the land use types in 2006 and 2016 respectively based on ＂3S＂ technology. Transfer matrix of land use and landscape index were calculated for each year. The results showed that forest land and cultivated land had been the main land use types of Anren County. The area of cultivated land increased and the area of forest land decreased during the study period. The area of the building increased, and the land use types were mainly converted to cultivated land during study period. The result also showed that fragmentation of Anren County was reduced, the diversity of landscape was increased and the patch distribution was more uniform and stable from 2006 to 2016. The study suggests that the process of urbanization has brought great pressure to the county forest landscape protection. In the process of urbanization, it is important to adhere to ecological principles and implement ecological planning, which is important for landscape protection and landscape pattern stabilization. The study can provide reference for the county scale ecological planning, which is of great significance to the county landscape protection.
