Abstract
Using meteorological station data, this paper analyzes the annual evapotranspiration and influencing factors in Fuping County from 1998 to 2017, and explores the dominant meteorological factors that affect the changes in evapotranspiration. The results show that from 1998 to 2017, the annual evapotranspiration in Fuping County showed a significant upward trend, with a growth rate of 9.9mm/a; The correlation between evapotranspiration and meteorological factors on a daily scale shows temperature>pressure>relative humidity>wind speed. There is a positive correlation between NDVI and evapotranspiration, with a correlation coefficient of 0.6693, indicating that surface evapotranspiration in the region is significantly influenced by underlying surface characteristics. Overall, temperature and vegetation are the main factors affecting evapotranspiration changes in Fuping County.
期刊介绍：
The IJISD focuses on broad aspects of innovation and sustainable development. It fosters discussion not only on technological innovation but on new ways of thinking about the complex and contested issues of sustainable development. Innovative thinking and practices in areas of economics, policy-making, legislation, health, education and the institutional barriers to sustainable development form the basis of the discourse to be fostered.
