The main reason of the lower soil net nitrogen mineralization rate in Eucalyptus forest could he the decrease of available substrates and the uptake of larger amount of soil nutrients by the fast growth of Eucalyptus. The soil nutrients in shrubland had a quick restoration rate after burning.

火烧桉林氮矿化速率较低的主要原因是其可利用基质的减少和桉树快速生长吸收大量养分所致，火烧灌草坡土壤养分的恢复速度较快。

Totally 60 sample plots were located by setting two lines which run through different habitats at a space distance of every 5km~2 along the East River basin and the West River basin in Baoxing, all of which cover different landuses of farmland, grassland, forestland, shrubland and abandoned land under different disturbances.

在调查区内沿东河、西河和宝兴河两岸0.5～1km~2处设置2条贯穿不同生境的样线，选取保存完整的、或退化的、或破坏的农地、草地、森林、灌木林地和荒地等各种土地利用类型设置典型样地。

In order to study the variations of fertile island during the process of desertification, the authors investigated and analyzed the soil chemical characteristics beneath and around the tamarisk shrub, the tamarisk δ^13C in saline meadow, tamarisk shrubland and sandy desert landscape in northern Taklamakan Desert, northwestern China.

为探索荒漠化过程中肥岛效应的变化规律，选择盐化草甸、灌丛及沙漠3种景观类型，测定了柽柳灌丛下和灌丛间空地土壤有机碳、全氮、水分含量以及柽柳营养枝δ^13C等指标，并用土壤养分的富集系数来表征肥岛效应的强弱。

At the shrubland habitats, warming resulted in less digestible shrubs, whosefoliage contains 25% digestible dry matter, replacing more digestible graminoids, whose foliage contains 60% DDM.

在灌丛地区，气候暖化使得含较少可消化物质的灌木，它们的叶子仅含有25%可消化的干物质，代替了含有更多可消化物质的禾本植物，后者的叶子含有60%的DDM。

In Eucalyptus forestland, soil organic carbon, total nitrogen, available potassium contents and soil PH decreased significantly; soil available phosphorus and exchangeable magnesium contents, net nitrogen mineralization rate and ammonification rate also decreased but showed no significant difference. In shrubland, soil exchangeable calcium content increased significantly, but the contents of other nutrients had no significant change.

结果表明：火烧3年后，桉林土壤有机碳、全氮、速效钾和pH含量明显降低，土壤有效磷、交换性镁、土壤净氮矿化速率和氨化速率降低，但不显著；火烧灌草坡除土壤交换性钙明显增加外，其他土壤养分均无显著变化。

This results indicated that peashrub shrubland created a favorable N condition for its invading the meadow and being invaded by birch forest, and played a important role in altering the successional direction of meadow→peashrub shrub land →birch forest.

尽管箭叶锦鸡儿灌丛植物叶片与凋落物中全N、全P浓度在大多数取样点上都低于硕桦，但表层土中全N浓度高于硕桦和草甸，且其土壤有机质的供氮能力以及维持氮素能力都高于硕桦林和草甸，表明，锦鸡儿灌丛为侵入草甸和硕桦入侵提供了良好的养分条件，在该演替序列的发展过程中起了一定的推动作用。

Nematode density, generic richness, diversity, and relative abundance of bacterivores and fungivores were higher at each stage of GT transect (from grassland to tea plantation) than at the equivalent stage of ST transect (from shrubland to tea plantation), whereas lower values of Maturity index and Nematode Channel Ratio occurred at each stage of GT transect relative to ST transect.

研究发现，GT系列各植物群落类型中的土壤线虫密度、属数、多样性、食细菌和食真菌线虫相对多度都高于ST系列中的相应植物群落类型，而土壤线虫总成熟指数和线虫通路比值均低于ST系列中的相应植物群落类型。

With different scenarios sediment discharge followed by grassland＞shrubland＞broad-leaved woodland＞orchard＞coniferous woodland,among the scenarios grassland made sediment diacharge increase while the others made sediment discharge reduce.Along with the forest cover increased,the runoff and sediment discharge decreased;meanwhile the sediment discharge had the maximum rate of descent with the forest coverage rate between 40-70%.

不同情景的输沙量依次为草地＞灌木林地＞阔叶林地＞园地＞针叶林地，与原地类比较草地使模拟输沙量增加，其余的情景都使模拟输沙量减少；不同森林覆盖率情景下年均径流和输沙量都随森林覆盖率的增大呈下降趋势，森林覆盖率在40-70%之间的输沙量下降速率最大。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
