Spatial patterns in resource supply drive variability in vegetation structure and function, yet quantification of this variability for tropical dry forests (TDFs) remains rudimentary. Several climate-driven indices have been developed to classify and delineate TDFs globally, but there has not been a climo-edaphic synthesis of these indices to assess and delineate the extent of TDFs. A statistical climo-edaphic synthesis of these indices is therefore required.

热带干旱景观中基于气候和土壤的归一化植被指数预测因子：泛热带分析

资源供应的空间模式驱动植被结构和功能的变异性，但对热带干旱森林 (TDF) 变异性的量化仍处于初级阶段。已经开发了几个气候驱动的指数来对全球 TDF 进行分类和描绘，但还没有这些指数的气候-土壤综合来评估和描绘 TDF 的范围。因此，需要对这些指数进行统计气候综合。
