In East and North Asia, satellite measurements and ground-based observations in recent decades demonstrate either an increase in the length of plant growth season over sub-regions or in some territories in line with climate warming, or do not show any significant trend in other territories . In recent decades in China, there has been an increasing trend in annual mean grassland net primary production , average leaf area index and lengthening of the local growing season . Nevertheless, phenology patterns vary across different studies, species and parts of China. In most regions of Northeast China, start date and length of land surface phenology from 2000 to 2015 had advanced by approximately 1 d yr-1, except in the needle-leaf and cropland areas . For Inner Mongolia, it has been shown
