摘要: 为了揭示湖北省黄石市土地利用景观格局的发展变化,合理利用土地,通过选取2004、2011、2016 年3期的landsat遥感影像,采用景观生态学原理和GIS技术,对各类用地进行土地利用变化分析。选取斑块数量、斑块密度、聚集指数、最大斑块指数、景观形状指数、蔓延度指数、香农多样性指数、香农均匀度指数等8个指数进行分析,研究黄石市近15 年的景观格局的发展规律。结果表明,农田、建设用地面积增加,林地、水域面积基本保持不变,裸地数量大量减少,景观连接性减弱,破碎度增加,景观格局复杂性增加,景观格局受人类活动影响加剧。

Abstract: To reveal the landscape pattern development and change of land use and rationally utilize land in Huangshi City, Hubei Province, the Landsat remote sensing images of 2004, 2011 and 2016 were selected to analyze the land use change of various types of land by adopting the theory of landscape ecology and the technology of GIS. The number of patches, patch density, aggregation index, the largest patch index, landscape shape index, contagion index, Shannon diversity index, and Shannon evenness index were selected to study the landscape pattern of Huangshi City in recent 15 years. The results showed that the area of farmland and construction land increased, the area of woodland and water area basically remained unchanged, the number of bare land decreased, the landscape connectivity weakened, the fragmentation increased, the complexity of landscape pattern increased, and the landscape pattern was aggravated by human activities.
