“…At present, the analysis of the effect of drought on water cycles' terrestrial carbon is a popular and meaningful research topic. It was reported that drought can cause a significant increase in WUE in natural ecosystems [49,50], but other researchers demonstrated that severe drought may obviously reduce ecosystem WUE [51,52]. In the present study, although there was strong spatial heterogeneity of the correlation coefficient (0.68, p < 0.05) between WUE and the TVDI (Figure 5f), the slopes of WUE and the TVDI presented good consistency in spatial distribution (Figure 4f,h).…”

“…It also provides e ective technical support for e cient water use and water conservation in farmland at the micro level. However, in comparison, the research results on the optimization of agricultural water use structure and water resources management are not very signi cant [17,18] northwest oasis irrigation areas of Gansu Province. When the irrigation quota of wheat and maize is 6750 m 3 /hm 2 , the yield can reach 15000 kg/hm 2 [19].…”

“…Other studies used intrinsic WUE which take into account the GPP and surface conductance [9,10] or inherent WUE, which considers the vapor pressure deficit in the ratio between GPP and ET [1,11,12]. Other studies even calculated WUE as the fraction of GPP and ET obtained from the Breathing Earth System Simulator (BESS) model [13][14][15][16].…”
