本文研究了海岸河口泻湖软质水域双壳类Chione stutchburyi Finlay，1927的细尺度密度分布。使用分层抽样程序进行了密度变异性的试点调查。密度进行了比较内和3个采样点之间，和网站内的变异性被证明是重要的。细尺度的空间和时间变异性的一个单一的系统采样网站超过30个月的调查期间，使用自相关技术进行了检查。系统采样和自相关技术的检测和描述的空间和时间模式的优势进行了讨论。
The fine-scale density distribution of Chione stutchburyi Finlay, 1927 (Bivalvia Veneridae) was studied in a soft shore estuarine lagoon. A pilot survey of density variability was made using a hierarchical sampling procedure. Densities were compared within and between 3 sampling locations, and within-site variability was shown to be important. Fine-scale spatial and temporal variability for a single systematically sampled site over a 30 mo survey period was examined using autocorrelation techniques. The advantages of systematic sampling and autocorrelation techniques for the detection and description of spatial and temporal patterns are discussed.
