The Yellow River Delta is a typical area of the fragile ecological environment. Evaluating human activity intensity quantitatively has a great significance to the ecosystem of the Yellow River Delta. Based on the remote sensing imagines of the Yellow River Delta from 1990—2018,land use information and using construction land equivalent were extracted,spatial autocorrelation analysis method was used to investigate temporal and spatial distribution of human activity intensity in the Yellow River Delta in the past 30 years,and the main driving factors of human activity intensity at different scales were explored. The results show that:(1)in the past 30 years,the impact of human activities on the land use of the Yellow River Delta was significant,the impact was the strongest from 1990 to 1997,the comprehensive dynamic degree of land use researched 2.17%; during this period,human activities had strong impact on forest land,water area,and construction land; their single land use dynamics were 16.70%,6.03% and 5.10%,respectively;(2)from 1990 to 2018,the distribution pattern of human activity intensity in the Yellow River Delta showed that fifth and sixth level intensity belts advanced towards east and north coast area,low intensity belts retreated from inland to the coast area; during the study period,the intensity of human activity significantly increased from 18.14% to 35.24%; Among them,the intensities of human activities in the urban construction area of Dongying district,salt field of Hekou district and Shengli Oil Field of Kenli district werer higher;(3)the results of the correlation coefficient showed that population density,salt field extraction volume and crude oil extraction volume of the Yellow River Delta were related the human activity intensities at 95% significant level. The main driving factors of different scales were significantly different. The urbanization rate,salt field extraction volume,crude oil extraction volume and GDP change rate are the main driving factors in Dongying District,Hekou District,Kenli District and Lijin County.
