  1. Sb: Stipa breviflora; Cs: Cleistogenes songorica.
  2. SM: soil moisture; STN: soil total nitrogen; STP: soil total phosphorus; TNg: green leaf nitrogen; TPg: green leaf phosphorus; TNs: senesced leaf nitrogen; TPs: senesced leaf phosphorus.
  3. Reported data correspond to correlation coefficients r with p values represents as bold asterisk (*, ** and *** indicate 0.01 < p < 0.05, 0.001 < p < 0.01, and p < 0.001, respectively).
