查询词典 shrub steppe

Biomass in the rain forest was far more than that in the plantation of 12 years,especially for the shrub layer.But the biomass of litterfall collected in the plantation was greater than that of the rain forest for the reason that Betula alnoidis defoliated in dry seasons.9 Four years observation found that soil bulk density tended to increase first, then decrease after planting trees;total soil porosity and non-capillary porosity tended to decrease and after few years they recovered to different degrees;the soil cation exchange capacity for all forest types increased;in the soil of 0-30cm depth,soil salt saturation tended to decrease;nutrient content in the soil of 0-60cm depth in the young stand tended to decline;soil effective P,effective K and N contents all tended to decrease.

山地雨林的总生物量远远大于10年生的西南桦人工林，其中灌木层的相对差别尤其巨大。94次的观测发现，人工林栽植后，土壤容重一般呈现一个先上升后下降的特点；而土壤非毛管孔隙度、土壤总孔隙度大多呈下降趋势，几年后有不同程度的恢复。

The plantation defoliated in dry seasons while the mountain rain forest was tall and dense evergreen broadleaved forest and kept green in dry season.The mountain rain forest\'s arbor layer contained 3 layers.Relatively open space under the canopy,rare shrub,sparse grasses,very tall wood vines and rich epiphytes were found in it.4 Afforestation did not change the life form spectrum significantly.

西南桦人工林的乔木层在旱季落叶，而山地雨林外貌为高大、常绿、茂密的阔叶林，即使旱季也仍保持林冠葱绿的外貌，乔木层可明显的分为3层，林下比较空旷，灌木植被少见，草本植物分散，另外具有高大的木质藤本植物和附生植物。4人工造林对群落的物种生活型谱影响不大。

The results showed that covering the dich slopes with shrub could significantly increase soil shear strength, compactness and moisture content, and the formed vegetation had significant effects on retarding runoff and removing TSS (P.05). Applying live fascines could significantly increase soil shear strength and TSS removal rate (P.05), but its effects on increasing soil compactness and moisture content and retaining runoff were not significant.

结果表明：与对照相比，使用灌丛垫技术修复后的坡岸土壤剪切力、紧实度和土壤湿度显著提高(P.05)，坡岸植被延缓径流和去除悬浮物效果显著(P.05)；使用柴笼技术修复后的坡岸土壤剪切力和悬浮物去除率显著提高(P.05)，但对土壤湿度、紧实度和雨水径流的延滞作用不太明显。
