基于InVEST的沁河流域产水量-碳储量时空演变及关联分析
Temporal and Spatial Evolution and Correlation Analysis of Carbon Stocks-Water Production in Qinhe River Basin Based on InVEST Model
摘要
Abstract
In order to address climate change and water resources pressures,and to achieve sustainable regional water resources utilization under the carbon neutrality target,the InVEST model was employed to assess carbon storage and water yield in the Qinhe River Basin from 2000 to 2020.The study also used geographical detectors to explore the driving factors and explanatory power,and spatial autocorrelation analysis to examine the spatial relationship between the two.The results show that:a)Water yield in the Qinhe River Basin has shown a fluc-tuating increasing trend,rising from 1.020 billion m3 in 2000 to 1.167 billion m3 in 2020.This change aligns with the trend in precipitation,with carbon storage and potential evapotranspiration being the main driving factors.b)Carbon storage decreases from 167.566 7 million tons in 2000 to 167.110 5 million tons in 2020,following a trend similar to soil carbon storage,with potential evapotranspiration and water yield being the primary driving factors.c)The global Moran's index of water yield and carbon storage is-0.2,showing no significant spatial dis-tribution overall.Spatially,there is a pattern of high water yield-low carbon storage and low water yield-high carbon storage.关键词
