图4. 气候和土壤因子与地上生态系统功能之间的关系。AEF, 地上生态系统功能值; AI, 干旱指数; ATP, 年降水量; MBC, 土壤微生物生物量碳含量; MBN, 土壤微生物生物量氮含量; SOC, 土壤有机碳含量; STN, 土壤全氮含量。除AEF外, 其余因子均为取对数后的数据。
Fig. 4. Relationships of climate and soil factors with aboveground ecosystem functions. AEF, aboveground ecosystem functions value; AI, aridity index; ATP, mean annual precipitation; MBC, microbial biomass carbon content; MBN, microbial biomass nitrogen content; SOC, soil organic carbon content; STN, soil total nitrogen content. Except for AEF, all other are log-transformed data.
