ANALYSIS ON THE TREND OF DISPERSED PATTERN OF CHINESE-PINE CATERPILLAR IN THE SEQUENTIAL PROCESS OF DURATION HIBERNATING LARVAE THROUGH UP THE TREE
在上树时间序列过程中,油松毛虫越冬幼虫扩散型变化的趋势分析

Trend of dispersion or aggregation of Hibernating larvae of Chinese-pine caterpillar was enuncited by measuring indices of aggregation from the beginning to the end through up the tree, the indices of aggregation were obtained by tree sampling, ring sampling and branch sampling. Then, the changing trend of dispersion or aggregation can be traited using Lloyd's method (1967) and harmonic analysis.
