摘要
为科学经营和合理利用小微湿地资源,实现小微湿地可持续发展,文章以广州市为研究区,选取2000 年、2010 年以及2020 年遥感影像数据,利用遥感和地理信息系统技术,提取出广州市小微湿地分布信息,采用空间自相关、质心迁移、冷热点分析等方法来分析广州市小微湿地的空间分布特征并通过地理探测器探究小微湿地变化的影响因素.结果表明,2000-2020 年间,广州市小微湿地的总面积和斑块数量均呈增加趋势.从空间分布上来看,小微湿地分布都呈聚类模式且皆为正向空间自相关性,热点区域逐渐向中部及南部区域扩大.广州市小微湿地的分布受年平均气温和GDP的影响较大.
Abstract
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.
