摘要
随着区域经济发展,人口不断增长,人地矛盾日益突出.掌握区域土地资源时空演变趋势,对缓解用地紧张,优化资源调配具有重要意义.收集郑州市2000年、2010年、2020年卫星遥感数据,利用监督分类方法提取郑州市用地类型信息,采用土地利用转移矩阵、Fragstats技术构建景观指数,综合分析郑州市2000-2020年土地利用及景观格局时空演变特征.结果表明:研究期间郑州市土地利用类型变化较为活跃,且主要集中在建设用地与耕地之间.景观格局分析表明:优势图斑具有聚合趋势,景观形状趋于规则化.
Abstract
With the development of regional economy and population growth,the contradiction between human and land has become increasingly prominent.Mastering the spatiotemporal evolution trend of regional land resources is of great significance for alleviating land scarcity and optimizing resource allocation.By collecting satellite remote sensing data from Zhengzhou City in 2000,2010,and 2020,extract land use type information using supervised classification methods,by constructing landscape indices using land use transfer matrix and Fragstats technology,and by comprehensively analyzing the spatiotemporal evolution characteristics of land use and landscape pattern in Zhengzhou City from 2000 to 2020,we get the results which indicate that during the research period,the changes in land use types in Zhengzhou City were relatively active,mainly concentrated between construction land and cultivated land.The analysis of landscape pattern shows that the dominant patterns tend to converge and the landscape shape tends to become regular.
