| 摘 要： | 研究首次比较了2种方法在测定荒漠草原6种植物种群分布格局中的适用性.结果表明,方差均值比率法及聚集强度指数法中的多个指数都适合于这6种植物分布格局的计算.但其中的聚块性指数法的运算难度较大,宜慎用.比较结果这6种植物种群皆为聚集分布,但聚集程度有所差别.

| Abstract: | Two methods were primarily used to measure the population distribution patterns of six plant species in desert steppe to determine their suitability.The results showed that many index from the method of Variance/Mean value and Clumping Degree Index were suitable for the calculation,but the latter was more difficult.The distribution patterns of the six plant species were clump patterns,but their clumping intensities were different. |
