摘要/Abstract

摘要： 为了分析在红松伐根分解的过程中土壤动物的动态变化，以阔叶红松林建群树种红松的伐根为研究对象，选取14 a跨度的红松伐根分解的残留物，分离出其中的大型土壤动物、中小型土壤动物，鉴定种类，统计计数。结果表明：随分解时间增加,土壤动物的类群和个体数逐渐增加，在伐根分解10年时达到峰值，随后减少；在伐根的地上部分，土壤动物的类群和个体数最多，随伐根深度的增加，土壤动物的类群和个体数逐渐减少，在伐根的最深部分很少有土壤动物活动。

Abstract: To study the dynamics of soil animals during the decomposition of Korea pine stump, a broadleavedKorean pine mixed forest after selective cutting was selected , and soil samples were collected in a 14-year span, with different size soil animals identified and counted. The results showed that the groups and numbers of soil animals increased with increasing decomp-osition duration, being the maximum in the 10th year, but decreased with increasing depth of the stump in soil, few of them being found at the bottom of the stump.
