摘　　要：Human activities are a triggering factor for landslides in the Yellow River Basin(YRB,China).However,the extent to which the spatial distribution of landslides is affected by human activities is unclear.We constructed a human activity intensity index(HAII)based on nighttime light data and land cover data.Regression and dominance analyses were used to compare the effects of the HAII,precipitation,distance to river,distance to fault,topographic relief and slope on the landslides spatial density(LSD).The results showed that in the YRB,the HAII,as a dominance influencing factor,had a significant positive influence on the LSD.Moreover,regional differences in the human disturbance of nature intensify the spatial variation of LSD.To quantify the intensity of human disturbance to nature,a human-nature conflict index(HNCI)is constructed by quantifying the difference between the slope distributions of artificial and natural landscapes.The results show that in the middle section of the YRB,humans are developing more steep mountainous areas,leading to more dense landslides.This study provides a reference for landslide risk management and land use planning in the YRB.
