【摘要】：采用連續(xù)3年全季節(jié)放牧、3種季節(jié)性輪牧、秋季刈割和不利用對(duì)照6種處理,研究了內(nèi)蒙古典型草原大型土壤動(dòng)物群落特征.調(diào)查在春、夏和秋3個(gè)季節(jié)進(jìn)行,共捕獲大型土壤動(dòng)物597只,隸屬于2門4綱11目,49個(gè)類群.結(jié)果表明:全季節(jié)放牧導(dǎo)致土壤動(dòng)物的個(gè)體密度、生物量和多樣性降低;而刈割的影響相對(duì)較輕,土壤動(dòng)物的個(gè)體密度、生物量和多樣性甚至有提高趨勢(shì).3種季節(jié)性輪牧處理中,夏季和秋季放牧2次處理對(duì)土壤動(dòng)物群落個(gè)體密度、生物量和多樣性等指標(biāo)的負(fù)面影響較輕.刈割管理對(duì)退化典型草原大型土壤動(dòng)物群落的恢復(fù)較為有利;夏季和秋季放牧2次處理對(duì)大型土壤動(dòng)物群落的負(fù)面影響較輕,是較理想的草地可持續(xù)管理措施.
[Abstract]:The characteristics of soil macrofauna community in typical grassland of Inner Mongolia were studied by three seasonal rotation grazing in three consecutive seasons, cutting in autumn and six treatments without using control. The investigation was carried out in spring, summer and autumn. A total of 597 large soil animals were captured, belonging to 2 phyla, 4 classes, 11 orders and 49 groups. The results showed that the individual density, biomass and diversity of soil animals were decreased during the whole season grazing, while the effect of cutting was relatively light, and the individual density of soil animals, The biomass and diversity even increased in the seasonal rotation grazing treatments in summer and autumn, the negative effects on individual density, biomass and diversity of soil fauna community were slight. Mowing management was beneficial to the restoration of macrofauna communities in degraded typical steppe, and grazing twice in summer and autumn had less negative effects on macrofauna communities, so it was an ideal sustainable management measure for grassland.
