为揭示枣树截形叶螨种群的空间结构特征，探究枣树截形叶螨防治方法，通过对枣树截形叶螨种群7～8月动态系统监测，应用5种聚集度指标和Iw ao法研究该螨在枣树树冠上的空间分布格局。结果表明：截形叶螨种群在枣树树冠垂直方向和不同方位均为聚集型分布，其中垂直方向下层＞上层＞中层，不同方位南面＞东面＞西面＞北面。初步摸清了枣树截形叶螨种群在枣树树冠上的空间格局分布及动态规律。

In order to reveal the spatial structure of jujube Tetranychus truncatus Ehara population and to ex-plore the control method ,through the monitoring for dynamic from July to August ,five kinds of aggregation in-dexes and spatial pattern were studied .The results showed that Tetranychus truncatus Ehara population was distributed in aggregation pattern in vertical direction and on different positions of the jujube crown ,the distri-bution on the lower level was more aggregated than that on upper level followed by that on middle .The distri-bution in the south was more aggregated than that in the east followed by west and north .The spatial distribu-tion pattern and dynamic laws of Tetranychus truncatus Ehara population on the jujube crown were studied preliminary and that would provide a scientific basis for the emphasis on prevention and treatment of Tetrany-chus truncatus Ehara .
