Relationships between interannual variations of spring vegetation green-up (SVG) and rainy season onset (RSO) across 67 sites during 2001–2013. (a) Spatial variability of correlation coefficients (R) between SVG and RSO dates during 2001–2013 for each of the 67 stations; different sizes of the circles indicate significant levels of the correlation coefficients (*P < 0.05; #P < 0.10; ns, not significant); the background is the distribution map of vegetation types, which was drawn using ArcGIS 10.3 for Desktop with the vector data for Vegetation Atlas of China (1:1,000,000)27 being available free online at https://www.geodata.cn/; the left inset shows the frequency distribution of pre-SVG mean temperature (T-30d) among the 67 sites. (b–e) Correlations between RSO and SVG dates during 2001–2013 in pooled data of the 67 sites (b) and in grouped data for alpine dry shrubs (c), alpine meadows (d) and alpine steppes (e), respectively; the 1:1 dashed line indicates the one-to-one relationship; ***P < 0.001.
