基于RS/GIS的赣州市生态系统服务价值时空演变特征研究
Study on the Temporal and Spatial Evolution Characteristics of Ecosystem Service Value in Ganzhou City Based on RS/GIS
摘要
Abstract
With the accelerated urbanization,the temporal and spatial dynamics of Ecosystem Service Value(ESV)have become crucial indicators for assessing regional sustainable development.This paper analyzes the land use data and ESV of Ganzhou City in China for the years 2000,2010,and 2020,aiming to unveil the spatiotemporal variations of ESV within this period and their correlation with land use changes.Employing Remote Sensing(RS)and Geographic Information System(GIS)technologies,land use types are accurately classified with the Random Forest algorithm.Subsequently,localized ESV coefficients were applied to compute and analyze the per-hectare ESV across various counties.The findings indicate a slight decline in Ganzhou's total ESV in the past two decades,which declines from 1 669.21 billion yuan in 2000 to 1 650.83 billion yuan in 2020.It is necessary to consider the protection and enhancement of ecosystem services in future urban planning and land management decisions to promote local sustainable development and ecological civilization construction.关键词
