摘　　要：研究种群空间分布、种间时空相关及种群与环境因子间空间相关的一维序列方法，包括一维序列抽样调查、单种群分布分析的方差图和相关图方法及时空相关分析的交叉相关图方法。提出了方向性和最大相关距离（平均聚集半径）这两个描述空间分布和空间相关的特征量；第一次用数量方法建立了研究空间分布与建立空间预测模型的统一的分析模型。例１说明了传统判断分布型方法存在的缺陷和用一维序列方法解决的途径；例２包括分布的时序分析、不同虫态空间分布的相关和不同世代幼虫空间分布的差异分析。A series of one dimensioanl(1 D) series models were developed in this study, in order to characterize the po pulation spatial pattern, the spatial correlation between different populations, and the spatial correlation between population and it′s living environment. The methods included 1 D spatial sampling, variogram, correlogram, and cross correlogram.The directional and range properties played a central role in the models. Also, the relationship among spatial correlation, spatial estimation, and spatio temporal forecast was studied. Two examples were introduced in this paper. The first example showed that the 1 D series analysis method was much better than the classical spatial pattern index methods when they were used to analyze spatial patterns. The second example introduced how to use the cross correlogram and time correlogram analyzing population spatio temporal dynamics.
