Population and economic development is important research contents in the field of sustainable development, and is an important carrier for realizing rural revitalization and regional high-quality development. In order to promote the high-quality development of the Loess Plateau region, it is necessary to have a new understanding and judgment on the relationship between population and economic vulnerability in the region of the Loess Plateau. This paper takes the county of Loess Plateau region as an example, utilizes the sensitivity-resilience model to evaluate the characteristics of economic vulnerability and its temporal and spatial changes in the Loess Plateau since 2000, and explores the effect of population changes on county economic vulnerability by ArcGIS spatial technology and gray correlation analysis. The results are as follows: 1) In 2000, the economic vulnerability grades of counties in the Loess Plateau were dominated by low and lower vulnerability grades, while in 2010, the area of low vulnerability areas decreased, and the areas of medium and high vulnerability increased significantly. In 2017, the area of low and low vulnerability grades increased, and the area of medium and high vulnerability areas decreased. In general, from 2000 to 2017, the overall economic vulnerability of counties in the Loess Plateau showed a significant trend of ‘increase first and then decrease’. 2) The overall economic vulnerability of the county in the Loess Plateau shows the spatial pattern of “high in the south and low in the north”. The counties with high and relatively high levels are mainly concentrated in the area of Liupan Mountains and Luliang Mountains; the middle-level counties are concentrated in the area of Longdong, Taihang Mountains and Luliang Mountains; the vulnerability level of the surrounding areas of counties, districts and prefectures under the jurisdiction of the provincial capital city is the lowest. 3) The population outflow rate, gender ratio, and the proportion of the elderly population, which represent population changes, are the key factors affecting the county economic vulnerability of the Loess Plateau, and the influencing factors of population changes on economic vulnerability in different periods are different.

Key words: economic vulnerability, population changes, county, the Loess Plateau region
