Characteristics of Land-use Change in the Surroundings of the Demoted and Retired Small Reservoirs in Guangdong Province
摘要
Abstract
Indicators such as single land-use spatial dynamic degree,comprehensive dynamic degree and change intensity were used to study the demoted and retired reservoirs in Guangdong Province from 2020 to 2022.A time-segmented statistical analyse was conducted to study the dynamic transformations and spatiotemporal change characteristics of land-use in the surroundings of these reservoirs during the period from 2000 to 2020.The results indicate that:① The land-use change of the studied area mainly occurred in the period from 2010 to 2020.And the main charactor of this change is the transformation from cultivated land,forest,and grassland to artificial surfaces.② The shrinking of cultivated land and expansion of artificial surfaces are the key driving factors to the demotion and retirement of these small reservoirs.③ Such driving transitions first occurred in the Pearl River Delta region and were most significant in the northern part of Guangdong Province.关键词
