However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.

但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化,西南桦人工林的层次结构有3层,以乔木层占优势,并且有种类多而发达的灌木层,同时,藤本植物欠发达,但是乔木层树种单一,明显仅有一层;山地雨林的层次结构有4层,以乔木层占优势,还有灌木层、草本层和藤本植物,藤本植物种类多,十分发达;乔木层树种丰富,可达38种,乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成,根据重要值的大小排列,人工林和天然林的主要物种组成已经完全不同;并且人工林单优树种明显,而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。

Results The mortality rate of mice in 80 mg/kg, day cyclophosphamide group was 16.7%, and T level [ at 30th day :( 1.38 ± 0.31 );45th day:( 1.15 ± 0.26 ) ] and T/LH ratio [ at 30th day:(0.163 ± 0.014); 45th day:(0.127 ± 0.023 ) ] were significantly decreased (all P<0.05) at 30th day after induction;The concentration of MDA [at 15th day:(2.70 ± 0.41);30th day:(2.710.36);45th day:(2.67 ±0.43) ] was maintained at a high level (all P<0.05) during the 45 days ; Number of Leydig's cells [ at 15th day:(9.65 ± 0.75 ); 30th day:( 14.05 ± 0.67 ); 45th day:(8.49 ± 072)] and layers of spermatogenetic epithelia [ at 15th day:(4.75 ± 0.82);30th day:(3.60 ± 0.49);45th day:(3.74 ± 0.43 ) ] were significantly decreased ( all P < 0.01 ) and stabilized in a low level. The induced model was stable and the mortality rate was acceptable. In the 60 mg/kg, day cyelophosphamide group, the T level and T/LH ratio had no significant change (P > 0.05 ), and the concentration of MDA ,number of Leydig' s cell and layers of spermatogenetic epithelia recovered at 30th day after induction. The induced model was unstable.

结果 剂量每日为80 mg/kg体重小鼠成模后死亡率为16.7%,血清T[30 d:(1.38±0.31);45 d:(1.15±0.26)]及T/LH比值[30 d:(0.163±0.014);45 d:(0.127±0.023)]于诱导后第30天出现显著下降(P均<0.05),而诱导后睾丸组织内MDA含量[15 d:(2.70±0.41);30 d(2.71±0.36);45 d:(2.67±0.43)]维持高水平(P均<0.05),生精上皮层次[15 d:(4.75±0.82);30 d:(3.60±0.49);45 d:(3.74±0.43)]和间质细胞[15 d:(9.65±0.75);30 d:(14.05±0.67);45 d:(8.49±0.72)]均显著减少(P均<0.01)并稳定于低水平,模型稳定,死亡率适当;每日60mg/kg体重组小鼠血清T及T/LH比值于不同时段并未出现明显变化(P>0.05),且睾丸组织内MDA含量、生精上皮层次和间质细胞计数在30 d后有所恢复,模型不稳定;每日100 rag/ks体重组死亡率为30.0%,死亡率过高。
