Clim.te warm.ng profoundly affects plant biodiversity, com.unity productivity, and soil properties in alpine and subalpine grassland ecosystem.. However, these effects are poorly understood across elevational gradients in subalpine m.adow ecosystem.. To reveal the elevational patterns of warm.ng effects on plant biodiversity, com.unity structure, productivity, and soil properties, we conducted a warm.ng experim.nt using open-top cham.ers from.August 2019 to August 2022 at high(2764 m.a. s. l.), m.dium.2631 m.a. s. l.), and low(2544 m.a. s. l.) elevational gradients on a subalpine m.adow slope of m.unt Wutai, Northern China. Our results showed that three years of warm.ng significantly increased topsoil tem.erature but significantly decreased topsoil m.isture at all elevations(Pm.erature and decreasing m.isture both gradually raised with elevation lifting. Warm.ng-induced decreasing proportions of soil organic carbon(SOC, by 19.24%), and total nitrogen(TN, by 24.56%) were the greatest at high elevational gradients. Experim.ntal warm.ng did not affect topsoil C: N, p H, NO_(3)^(-)-N, or NH_(4)^(+)-N at the three elevational gradients. Warm.ng significantly increased species richness(Pm.ss(Pm.at three elevational gradients. Warm.ng caused significant increases in the aboveground biom.ss in the three elevational plots.
