| 摘要: |
| 研究分析了深圳市3 个市级自然保护区的土壤化学计量特征与植物多样性的相关性，结果表明：植物多样性指数多与土壤表层的C、N、P 化学计量比显著相关，但相关性较为复杂。其中大鹏自然保护区的植物均匀度指数（E）和田头山自然保护区的植物丰富度指数（R）与土壤表层的C、N、P 化学计量比呈显著的正相关性。但田头山自然保护区植物多样性指数（H""）、优势度指数（S）、均匀度指数（E）指数与土壤表层的C:P 和N:P 显著负相关。而铁岗—石岩湿地自然保护区的植物多样性指数与土壤C、N、P 化学计量比均没有显著的相关性。 |

| Abstract: |
| This paper analyzed the relationships between soil stoichiometric characteristics and plant diversity indices in three nature reserves in Shenzhen. The results showed the relationships between soil stoichiometric characteristics and plant diversity indices are complicated, and most significant relationships happened in shallow soil (0-20 cm). The evenness index in Dapeng nature reserve and the plant species richness in Tiantoushan nature reserve were positively correlated with soil stoichiometry characteristics in shallow depth (0-20 cm) significantly. While the diversity index, plant dominance index, and evenness index were negatively correlated with soil C:P and N:P ( 0-10 cm) in Tiantoushan nature reserve significantly. In Tiegang-shiyan nature reserve, there were no significant relationships between soil stoichiometric and plant diversity indices. |
