| 中文摘要: |
| 物种丰富度是反映物种多样性的指标之一，研究物种丰富度与环境因子的关系对自然保护区的发展、规划和管理具有重要意义。研究选取广东省已经进行过深入调查的19 个自然保护区为样本，对物种丰富度（科数、属数和种数）及环境因子（经度、纬度、海拔、年均温度、无霜期、年均降雨量、相对湿度、面积）的关系进行分析。结果表明，物种丰富度与经度呈显著负相关，与海拔呈显著正相关。 |
| 英文摘要: |
| Species richness is an indicator of species diversity. It is of great significance to study the relationship between species richness and environmental factors on the development, planning and management of nature reserve.Nineteen nature reserves in Guangdong province with detailed background data were selected for this research.Relationship between the species richness (number of family, genera and species) and environmental factors (longitude,latitude, altitude, annual average temperature, frost free period, the average annual rainfall, relative humidity, the area) was analyzed. The results showed that the species richness was negatively correlated with longitude, and positively correlated with altitude. |
