2013年～2017年景观格局变化分析——以金普新区为例

Analysis of Landscape Pattern Changes from 2013 to 2017——A Case of Jinpu New Area

以多种卫星影像和航摄相片为数据基础,对金普新区空间格局变化监测中2013年、2015年、2016年和2017年四个时相的生态景观类型进行分类,提取生态景观类型的矢量图斑,并转化为栅格数据,又基于景观尺度对金普新区进行全面的分析,分析结果表明:2015年~2017年各类型的斑块密度没有较大变化,总体呈现逐年递减的趋势,而该3年与2013年的斑块密度指数差异较大;2013年~2017年新区内各类型景观的形状指数均呈现草地>耕地>人工绿地>园地>林地>水域>人工水域的趋势;景观的分割程度严重。研究成果对于调整新区生态改善具有重大意义,并为新区走可持续化发展路线打下坚实的基础。

Multiple satellite images and aerial photographs as data sources, we classify the ecological landscape types in four phases of 2013s, 2015s, 2016s and 2017s in the monitoring of spatial pattern change in Jin Pu new area,Based on the landscape scale, a comprehensive analysis of the new area was carried out, and the results showed that：In 2015s - 2017s, the patch density of all types did not change significantly, showing a decreasing trend year by year. The difference between the 3 years and the patch density index in 2013s is quite different. The shape index of various types of landscapes in the new area in 2013s-2017s showed the trend of grassland 〉 cultivated land 〉 artificial green land Garden 〉 woodland 〉 water area 〉 Artificial waters. The segmentation degree of the landscape is serious. The research results are of great significance to the adjustment of the ecological improvement in the new area, and lay a solid foundation for the sustainable development of the new area.
