生态位理论在建设生态园林城市中的应用初探

Application of Niche Theory in the Construction of Ecological Garden City

通过对立地条件类型相同城市的园林绿地植物生长状况进行调查,运用ArcMap软件计算各种群的重要值;采用Shannon-weinne多样性指标、Levins生态位宽度指数和1994年黄英姿提出的生态位重叠计算公式进行种群生态位宽度的研究,将种群生态位理论运用于生态园林建设中。

Based on the investigation of the growth status of gardens plants with the same site conditions, the important values of populations were calculated with the software of ArcMap, the niche breadth of populations were studied using the Shannon-weinne diversity index, Levins niche breadth index and niche overlap.
