浙江省湿地变化检测及驱动力分析

Detection of changes in various types of wetlands in Zhejiang province and analysis of their driving forces

面对全球气候变化,要加强湿地保护,认识湿地重要性,合理利用湿地资源,研究分析湿地变化及其驱动力,促进湿地保护和人类可持续发展。文章使用Landsat OLI和OLI-2系列影像,采用监督分类和非监督分类中5种典型的分类方法进行浙江省湿地信息的提取,得到2013—2023年浙江省湿地分布及变化数据,并进行驱动力分析,发现浙江省湿地空间格局的变化受社会经济因素与自然因素的共同影响。研究结果为浙江省湿地发展、湿地保护和土地利用规划提供了一定的科学依据。

In the face of global climate change,we should strengthen wetland protection,understand the importance of wetlands,make rational use of wetland resources,study and analyze wetland change and its driving forces,and promote wetland protection and sustainable human development.This paper using Landsat OLI and OLI-2 series image,using the supervised classification and unsupervised classification method of five typical of wetland information extraction in Zhejiang province,2013-2023 Zhejiang province wetland distribution and change data,and the driving force analysis,found that the change of wetland spatial pattern in Zhejiang province by the influence of social and economic factors and natural factors.The findings of this study provide a certain scientific basis for wetland development,wetland protection and land use planning in Zhejiang province.
