    Published 2025-02-01
    “…Subsequently, the Pearson Correlation coefficient (Pearson, R) analysis, considering the influence of drought on time-lag and -accumulation effects, was used to analyze the response mechanism of water use efficiency to scPDSI in BC and YM comparatively. The results show that (1) From 2001 to 2020, BC’s average annual WUE was 2.59 gC m−2 mm−1, and YM’s was 2.84 gC·m−2·mm−1, with similar spatial distributions. (2) Over the past 2 decades, BC’s WUE increased steadily at a rate of 0.012 gC m-2 mm−1 a−1, while Yuanmou’s WUE grew at 0.0082 gC m-2 mm−1 a−1. (3) The lag response of WUE to drought is minimal in both regions, with BC’s cultivated land showing greater sensitivity to drought than YM. (4) The cumulative effect of drought on WUE across different land uses in both BC and YM is generally small, with the lowest sensitivity in forest land to drought.…”
