基于InVEST模型的黄河流域砒砂岩区土壤保持功能演化及驱动机制
Evolution and Driving Mechanisms of Soil Conservation Function in Pisha Sandstone Area of the Yellow River Basin Based on the In VEST Model
摘要
Abstract
Studies of regional soil conservation function change and the mechanism of environmental driving factors have important theoretical significance for regional ecological environment construction,and can provide reference for soil and water conservation.In this study,the change of soil conservation function of the ecological environment system in the Pisha Sandstone area of the Yellow River Basin in the past 20 years was analyzed with the help of the InVEST model,and analyzed the dominant factors of soil conserva-tion function and the influence of pair-wise interaction on soil conservation by using the factor detector and interaction detector in the geodetector.The results indicated that 1)soil erosion in the Pisha sandstone area showed an improvement trend during 2000-2020,and the main erosion was slight.The average erosion modulus during the study period was 922.44 t·km-2·a-1.2)The spatial distribution of soil conservation function was basically the same as that of erosion,showing the distribution trend of.The changes in soil conservation in the study area were mainly unchanged,and enhanc for 2.47％and 3.62％of the total.3)The vegetation coverage played an absolutely dominant role in soil conservation function in Pisha area,and under the interaction of factors,it was more helpful to improve the soil conservation function.The ex-planation of vegetation coverage and precipitation the strongest,45.61％.关键词
