图6. 气候和土壤因子对地上生态系统功能值(AEF)的效应。图上表示的均为显著影响的路径(p < 0.05), 实线表示正效应, 虚线表示负效应。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。
Fig. 6. Effects of climatic and soil factors on aboveground ecosystem functions value (AEF). The path with significant effect is shown in the figure (p < 0.05), the solid lines indicate a positive effect and the dotted line indicates a positive effect. 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.
