草地

3Started with the ecosystem structure and function, constructed the index system of grassland ecosystem health evaluation. And selected eight quantitative and two qualitative indices, including the production, community coverage, litter biomass, excellent forage proportion, forage crude protein, soil compaction, soil organic matter, soil microbial biomass nitrogen and dominance species and life form synusia composition, as the sensitive indices of typical steppe health evaluation.

3从生态系统结构与功能入手，构建出典型草原健康评价的指标体系，并进一步筛选出典型草原健康评价的敏感指标包括草地产草量、群落盖度、地表凋落物、优良牧草比例、牧草粗蛋白、土壤紧实度、土壤有机质、土壤微生物量氮8项定量指标以及优势物种组成和生活型层片构成2项定性指标作为典型草原健康评价指标。

The results show that: the natural grassland and highest water content of Tamarix were 13.44% and 13.52%.

研究结果表明：天然草地和柽柳的含水量最高，分别为13.44%和13.52%。

I see the tumuli of Mongolia, I see the tents of Kalmucks and Baskirs

我看见花岗岩的圆石和悬崖，我看见葱绿的草地和湖泊

A chance to punch out the boss without getting summarily turfed.

有机会冲出来的老板没有得到简易程序草地。

Mature lawns can really benefit from this little extra kick of nutrients but be aware that newly seeded or turfed lawns can be scorched by it.

成熟的草坪能真正受益於这种一点额外的营养物质，但球都知道，新草坪种子或草地，可以由它烧焦。

According the difference of plant community in Daqinggou Nature Reserve, the environment was divided into 7 kinds of habitats, they are Fraxinus mandshurica plant community, Quercus mongolicus plant community, Ulmus macrocarpa plant community, conifer community, lakefront plant community, paddy field plant community and grassplot plant community in sandlot.

按照植物群落的不同将保护区内的环境划分为7种生境，分别为水曲柳植物群落、蒙古栎植物群落、大果榆植物群落、针叶林植物群落、湖边湿地植物群落、稻田植物群落和沙丘草地植物群落。

Moreover, on the free surface of the lake in Stephen's green amid inverted reflections of trees her uncommented spit, describing concentric circles of waterrings, indicated by the constancy of its permanence the locus of a somnolent prostrate fish.

而且，她连招呼也没打一声就朝着&斯蒂芬草地&那浩森的湖面上啐了一口，唾沫浮在一棵棵树的倒影之间，划下一圈圈同心圆的波纹，持久而凝然不动，以一条人睡般平卧着的鱼为记号。

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

Planted forests can deplete deep soil water, forming an obstacle to sustainable land use in the semi-arid area of Loess Plateau. The purpose of this study was to examine effects of grazing and cropping on replenishment of deep soil water where forest plantations had depleted soil moisture at depths of 2～9.9 m. We compared soil moisture on plantation plots with that on plots where plantations were replaced by crops, grazed grassland, and ungrazed grassland seperately.

为了研究黄土丘陵半干旱区人工林迹地土壤水分恢复情况，该文以正在生长的人工林土壤水分含量为人工林迹地土壤水分恢复的起点，并分别以持续农地和持续放牧荒坡的土壤含水量为林后农地和草地土壤水分恢复的上限，对位于黄土丘陵半干旱区绥德县境内的人工林迹地土壤水分恢复情况进行了研究。

They traded blows together for hours after chores were finished, at first staging their mock battles in the stables until Shem Horsegroom threw them out for the peace of his wards, then moving to the unmowed grass just south of the tourney field.

他们干完活以后，就几小时几小时地对练，开始，他们把模仿战役的舞台，安排在马厩里，直到有一天，马夫Shem，为了他的地盘能安宁，就把他们给撵了出去，于是，他们就来到这比武场南边，没有割过的草地练剑。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
