伊洛河流域水源涵养能力时空变化及驱动因素分析
Analysis of Spatial-Temporal Changes and Driving Factors of Water Conservation Capacity in the Yiluo River Basin
摘要
Abstract
In order to master the spatial-temporal changes and its driving factors of water conservation capacity in the Yiluo River basin,this paper adopted the InVEST model and water conservation calculation methods to quantitatively assess the water conservation capacity in the Yi-luo River basin from 2005 to 2020.It analyzed the spatial-temporal variation characteristics and quantitatively examined the driving factors of water conservation function by using geographic detectors.The results show that a)from 2005 to 2020,the water conservation capacity in the Yiluo River basin shows a trend of initial decrease followed by an increase.The highest water conservation capacity is observed in 2005,while the lowest is in 2015.b)The southern and western mountainous areas exhibit stronger water conservation capacity,whereas the cen-tral,northern and eastern regions are relatively weaker.c)During the study period,the ranking of water conservation capacity across differ-ent land use types from strongest to weakest is grassland,forest,shrubland,construction land,farmland,unused land and water bodies,with densely vegetated areas demonstrating stronger water conservation capacity.d)Precipitation is identified as the primary factor influencing changes in water conservation capacity in the Yiluo River basin,and the interaction between precipitation and land use has the most signifi-cant impact on water conservation capacity.关键词
