英文摘要	Leaf economics and hydraulic traits are critical to leaf photosynthesis, yet it is debated whether these two sets of traits vary in a fully coordinated manner or there is room for independent variation. Here, we tested the relationship between leaf economics traits, including leaf nitrogen concentration and leaf dry mass per area, and leaf hydraulic traits including stomatal density and vein density in five tropical-subtropical forests. Surprisingly, these two suites of traits were statistically decoupled. This decoupling suggests that independent trait dimensions exist within a leaf, with leaf economics dimension corresponding to light capture and tissue longevity, and the hydraulic dimension to water-use and leaf temperature maintenance. Clearly, leaf economics and hydraulic traits can vary independently, thus allowing for more possible plant trait combinations. Compared with a single trait dimension, multiple trait dimensions may better enable species adaptations to multifarious niche dimensions, promote diverse plant strategies and facilitate species coexistence.; Ailaoshan Station for Subtropical Forest Ecosystem Studies, Chinese Academy of Sciences; Dinghushan Station for Subtropical Forest Ecosystem Studies of South China Botany Garden, Chinese Academy of Sciences; Xianhu Botanic Park of Shenzhen; Xishuangbanna Station for Tropical Forest Ecosystem Studies of Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences; Jianfengling Tropical Forest Ecosystem Station; Jianfengling Nature Reserve Management Bureau; Natural Science Foundation of China (NSFC) [31325006, 31321061, 40971030]; Chinese Academy of Sciences [KZZD-EW-TZ-11]; SCI(E); PubMed; ARTICLE; zengh@pkusz.edu.cn; guodl@igsnrr.ac.cn; 9; 899-906; 18
