| Abstract: | Objective] The purpose was to use the basic functions of Microsoft Excel 2003 to conduct data processing,so as to calculate the commonly used parameters such as Levins niche breadth value and Pianka niche overlaps rapidly and efficiently.Method] Setting Quercus acutissima community in Zijishan mountain in Nanjing as an example,the niche data of main dominant tree species in this community were analyzed by Microsoft Excel 2003.Result] The niche breadth values of Q.acutissima and Pistacia chinensis were 0.68 and 0.47 resp.The niche overlaps between Q.acutissima and the other 8 species were 0.706,0.862,0.648,0.690,0.569,0.839,0.623 and 0.833 resp.,which were 0.485,0.772,0.416,0.498,0.490,0.612 and 0.324 resp.between P.chinensis and the other 7 species,0.588,0.523,0.821,0.653,0.548 and 0.615 resp.between Liquidambar formosana and the other 6 species and 0.653,0.726,0.193,0.549 and 0.176 resp.between Pinus massoniana and the other 5 species.Conclusion] Microsoft Excel 2003 had advantages such as wide application and good practicality,which was worth of further spreading and applying in the calculation and analysis of community parameters. |
