遵义市中心城区景观格局时空变化研究

Study on Changes of Landscape Pattern in Central District of Zunyi City

  • 摘要: 基于1998—2018年5期遥感影像数据,采用监督分类和目视修正相结合的方法进行遥感影像解译,运用景观面积转移矩阵和景观格指数,对遵义市中心城区景观格局变化特征进行分析。结果表明:1998—2018年,遵义市中心城区农田主要转换为道路交通和城乡人居及工矿用地,林地主要转换为农田、城市公园绿地和城乡人居及工矿用地;研究区整体景观破碎化程度持续增加,斑块形状越来越简单,土地利用越来越丰富,其不定性的信息含量也越大,斑块逐渐呈现均匀分布的空间特征。人口增加、经济增长、工业发展及产业结构调整是遵义市中心城区景观格局演变的主要驱动力。本研究可为遵义市中心城区城市用地开发和城市空间发展战略的制定提供参考。

     

    Abstract: Based on the remote sensing image data from 1998 to 2018, the method of combining supervised classification and visual correction is used to interpret the remote sensing image, and the landscape area transfer matrix and moving landscape grid index are constructed to analyze the landscape pattern change characteristics of Zunyi downtown. The results show that from 1998 to 2018, the farmland in the central urban area of Zunyi was mainly converted into road traffic, urban and rural residents and industrial mines, while the forest land was mainly converted into farmland, urban park green space, urban and rural residents and industrial mines; the overall landscape fragmentation degree of the study area continued to increase, the shape of the patches became more and more simple, the land use became more and more diversified, and the information content of the uncertainty was also larger, and the patches gradually presents the spatial characteristics of uniform distribution. Population growth, economic growth, industrial development and industrial structure adjustment are the main driving forces of landscape pattern evolution in Zunyi downtown. This study can provide a reference for the land development and spatial development strategy in the central district of Zunyi City.
