Figure 2
The annual spatio-temporal distribution of mean precipitation depth (1/θ) in China. The map was generated by the software ArcGIS 10.1. (a) mean of mean precipitation depth (1961–2015). (b). gradient of mean precipitation depth (slope)(1961–2015). (c) precipitation region with significant deviation (p < 0.1) of mean precipitation depth(1961–2015). (d) Mann–Kendall trend analysis and simple linear regression of mean precipitation depth(1961–2015). (e) precipitation region with significant deviation (p-value < 0.1) of mean precipitation depth in spring. (f) precipitation region with significant deviation (p-value < 0.1) of mean precipitation depth in summer. (g) precipitation region with significant deviation (p-value < 0.1) of mean precipitation depth in autumn. (h) precipitation region with significant deviation (p-value < 0.1) of mean precipitation depth in winter.
