The results indicated that vegetation biomass had a significant positive relationship with vegetation coverage. They had a significant negative correlation with bulk density of soil, and a positive correlation with macroaggregate, water stability macroaggregate, organic matter content, total nitrogen content, hydrolyzable nitrogen content, available kalium content, microbial biomass, and microbial respiration. However, they had no significant relationship with total phosphorus and available phosphorus.

在其恢复过程中,植被地上生物量与植被覆盖度呈正相关,它们与土壤容重呈负相关,而与土壤大团聚体、水稳性大团聚体、有机质含量、全氮含量、水解氮含量、速效钾含量、微生物量以及土壤呼吸强度之间呈正相关,与土壤全磷、速效磷含量无显著相关性。

Results showed that biomass of the ground part of Juncus Effuses was inhabited to a certain degree. When the dosages of the heavy metals added to the soils were close to Grade II Criteria of the State Soil Environmental Quality Standard (GB15618-95), Juncus Effuses could still grow normally in appearance though its yield decreased by 10%, however biomass of the underground part was not much affected.

实验结果表明:5种重金属复合污染对灯心草地上部生长有一定程度的抑制作用,在土壤环境质量二级标准上限值处灯心草地上部生物量减产9.15%,0%,但地下部生物量减产趋势不明显。

On the sampling scale of 20 m, the road effects on different dominant populations were demonstrated in their spatial distribution patterns. There were significant increases in the biomass of Schima superba population, the number of individuals and biomass of Litsea rotundifolia population (P.05) along the parallel direction to road, respectively, while those of other populations had no significant difference.

优势物种20 m取样尺度的空间分布格局反映了不同种群对旅游路径干扰的不同响应,其中荷木的生物量、豺皮樟的个体数和生物量在远离旅游路径方向上均呈显著增长趋势,其他物种的个体数和生物量变化不显著。

As known as traditional viewpoint, microbe could produce hydrogen continuously only when microbic cell is fixed, so present tests of this process offen adopt this process fixed-cell technology of pure microbe and were in the scale of batch fermentation test. Now the larggest ability of bio-producing hydrogen was 20mLH〓/g biomass·h produced by Rhodospirillum rubrum and 1. 6mLH〓/g biomass·h produced by Clostridium butyricum .

传统观点认为,微生物惟有进行细胞固定化才能达到持续产氢,所以现有试验常采用纯种细胞固定化技术,且尚处于分批培养试验阶段,最大产氢能力深红螺菌为20mLH〓/g菌体·h,丁酸梭状芽孢杆菌为1.6mLH〓/g菌体·h。

With the increasing of water lever, Myriophyllum spicatum increased the plant height, allocated more biomass to their leaves and decreased the allocation to roots and stems. However, Potamogeton maackianus allocated most biomass to their stems and decreased the allocation to leaves and roots.

实验发现:随着水位上升,狐尾藻株高也增加,并且将更多的生物量分配到叶片部分,减少对根和茎的资源投入;而微齿眼子菜则将生物量大部分投入到茎杆,减少对叶片和根的资源分配。

Mytilus edulis dominated the biomass and density of the macrobenthic fauna on the two sections. The biomass and density of the mid intertidal zone were greater than those of the low zone.

中潮带的生物量和平均栖息密度远大于低潮带;贻贝作为绝对优势种主导着2个断面生物量和栖息密度的分布特征。

Total submergence largely decreased biomass production and growth in length,with less effect on shoot numbers.Increased elongation of the growing internodes of up to 140% is caused by submergence.Nutrient such as N,P,K do significantly affect on growth.No mater lack of any element will decrease the biomass,the result same as the oligotrophic conditions.But lack of phosphorus is the worst mater.

而淹没式淹水可能使生物量降低,但是植株的高度有所增加,因为淹水可以使芦苇的节间高度提高140%;对根茎的数量没有很明显的影响。N、P、K等营养元素对芦苇生长也具有重要的作用,无论缺少哪一种对芦苇生长都不利,跟完全贫营养状态没有明显的区别,但是缺P时芦苇生长是最差的。

The individual growth,morphology and population biomass of Pennisetum centrasiaticum clones at two different habitats of farmland-sand dune ecotone on Keerqin sandy land of Inner Mongolia were compared in this study.P.centrasiaticum clones had significant morphological plasticity and different biomass distribution pattern at different habitats.

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是:以空气为气化剂的气化方式,得到的气体N_2和焦油含量高,热值一般在5000kJ/Nm~3左右;流化床气化工艺操作复杂,推广应用存在较多困难;直接干馏热解,虽气体的热值高(14000kJ/Nm~3),但产气率低(0.35m~3/kg)。
