摘　　要：初步探查了杨树直角叶蜂幼虫在＂欧美108＂林地中的空间分布特征.结果表明：杨树直角叶蜂幼虫主要分布于距地面1.3~1.9 m的树冠部分,依据空间分布聚集度指标判断,杨树直角叶蜂幼虫在调查林地中主要是聚集分布.The spatial distribution pattern and dispersal characteristics of Stauronematus compressicornis larvae in poplar forest land of Populous euramericana 108 were investigated. The results showed that S. compressicornis larvae mainly dis tributed in the crown part which was 1.3-1.9 m height above the ground. According to the measurement of indices of crowding level,larvae of S. compressicornis mainly present aggregated distribution in the woodland.
