Analysis of Small and Micro Wetland Resources in Guangzhou
To scientifically manage and reasonably utilize small and micro wetland resources,and achieve sustainable development of small and micro wetlands.This article takes Guangzhou city as the research area,se-lecting three periods from 2000,2010,and 2020.Using remote sensing and geographic information system technology,based on the collection of Landsat remote sensing data and GlobeLand30 land use data in the re-search area,the distribution information of small and micro wetlands in Guangzhou city is extracted.Spatial au-tocorrelation,centroid migration,and analyzing the spatial distribution characteristics of small and micro wet-lands in Guangzhou using methods such as cold and hot spot analysis,and exploring the influencing factors of small and micro wetland changes through geographic detectors.The results indicate that from 2000 to 2020,the total area and quantity of small and micro wetlands in Guangzhou showed an increasing trend.From a spatial dis-tribution perspective,the distribution of small and micro wetlands shows a clustering pattern and positive spatial autocorrelation,with hotspots gradually moving towards the central and southern regions.The distribution of small and micro wetlands in Guangzhou is mainly influenced by the annual average temperature and GDP.
