摘要:
为了解采伐干扰对巨桉人工林土壤动物的影响,采用手捡法和干湿漏斗法对四川省洪雅县巨桉人工林采伐干扰前和干扰后土壤动物群落进行调查. 结果显示:巨桉人工林采伐干扰前后共获大中小型土壤动物5 578头,分属4门10纲25目,采伐干扰后共减少1 290头,类群数减少了3个. 采伐干扰前后中小型湿生、干生土壤动物剖面分布具有明显的表聚性,均与地温呈负相关,与土壤有机质含量和土壤含水量呈正相关. 采伐干扰对各层中小型湿生、干生土壤动物个体数均有极显著影响(P < 0.01),并导致Shannon-Wiener(H′)多样性指数和Pielou(J)均匀性指数增加,密度-类群指数(DG)减小,Simpson(C)优势度指数无显著变化,表明采伐干扰对巨桉人工林土壤动物群落结构有较大影响. 表6 参33
Abstract:
In order to understand the response of soil animal community to harvesting disturbance and evaluate the ecological effect of a eucalypt plantation, an investigation on soil fauna was carried out in the eucalypt (Eucalyptus grandis) plantation which was planted in 1997 and harvested in August 2006. Soil macro-fauna were picked up by hand. Nematodes and mesofauna were separated and collected from the soil samples by Baermann and Tullgren methods, respectively. Totally, 5 578 individuals of soil fauna, belonging to 4 phyla, 10 classes and 25 orders were collected before and after felling disturbance, and the individuals of soil fauna were 1 290 fewer than those before felling. Individuals were easier affected by felling disturbance than group numbers. Acarina, Hymenoptera and Nematode occupied 91.76% of the total decreased individuals, Collembolan 88.99% of the total increased individuals, and other soil fauna changed insignificantly. The meso-micro soil fauna (including those collected by Baermann and Tullgren methods) were mainly distributed in top soil layer, which was negatively correlated with soil temperature, and positively with soil organic content and soil moisture. The felling disturbance represented a significant effect on meso-micro soil fauna (P < 0.01). Shannon-Wiener (H′) and Pielou (J) indexes increased significantly ( P > 0.05), DG index decreased extremely significantly ( P < 0.01), Simpson(C) index of plot A decreased and plot B increased, indicating that harvesting disturbance had induced significant effects on the structure of soil fauna in the eucalypt plantation.
