- 摘要:
- 在分析了目前植物多样性研究中取样技术存在的一些问题之后，着重介绍了改进的Whittaker取样方法。Whittaker方法是一种标准的多尺度嵌套式长方形取样技术，而改进的Whittaker方法是对这种方法的进一步完善和充实。这种取样方法的应用将有助于降低空间尺度对物种丰富度的影响，使之更为有效地量度和预测不同生态系统的物种丰富度，特别是对空间异质性较大的生态系统更具有较高的实用价值。
- Abstract:
- After analyzing some problems on the plant diversity sampling techniques, Whittaker’s and Modified Whittaker’s sampling method is presented emphatically. Whittaker’s method is a standardized approach to quantify species richness at multiple spatial scales, and modified Whittaker’s method further improved Whittaker’s method. Readers can know about the two methods, and can also get some information for the future sampling work.
