The bees also play a vital role in pollinating flowers to sustain vegetation.

蜜蜂也扮演传播花粉以维持植物生长的关键角色。

In a word, differential coefficient and vegetation index were much effective than reflectance for corn FPAR estimating, and the stepwised regression of multibands differential coefficient showed the best regression with R^2 of 0.944.375 nm purpled band and 950 nm near-infraed band absorbed by water showed prodigious potential for FPAR estimating precision.

除红、绿和常用的近红外波段外，375nm附近紫色波段和950nm附近的近红外波段用于估算FPAR也可以得到较理想的结果，特别是水分强吸收的波段具有较好的提高FPAR估算精度的潜力。

Diversity between two quadrates within a community decreased with increasing elevation. The peak values of dissimilarity index and Cody index along elevation gradient just matched the ecotones between different vegetation types.

群落内的β多样性随海拔的升高而下降，而群落间的β多样性可以很好地反映群落间的相似性关系，β多样性较大的几个峰值恰好是不同植被类型间的分界。

Based on the survey of community plots, a quantitative analysis of the communities at Luya Mountain is performed with TWINSPAN Two Way Indicator Species Analysis and DCA Detrended Correspondence Analysis methods. 82 quadrates collected from Luya Mountains were classified into 28 types by TWINSPAN, which belong to seven vegetation types. The result of DCA indicated that those 28 types were reliable. Diagonal line of the two-dimensional ordination diagram of DCA reflects the gradient changes of elevation, temperature and humidity. It is considered that the major factors that restrict the community distribution of the mountains are elevation、temperature and humidity.

本文在群落样方调查基础上，采用双向指示种分析法TWINSPAN和除趋势对应分析DCA对山西芦芽山植物群落进行数量分类和排序TWINSPAN等级分类将芦芽山82个样方分为28类，可归属于7个植被型，分类结果反映了植物群落类型与环境梯度之间的关系，并在 DCA二维排序图上得到较好的验证DCA排序轴对角线基本反映了海拔、温度和湿度的梯度变化，表明群落生境所在地的海拔、温度和湿度是决定群落分布的主要因素

Therefore,reconstructing more believable vegetation in East Asia is important to reduce the uncertainties.

因此，重建可信度高的东亚植被对于降低对气候模拟的不确定性是十分重要的。

Also the results indicated that soil properties could be changed by length of reforestation and soil quality index increased with vegetation recovery. The similarity index decreased for larger year interval between two reforested lands.

群落特征变化随林龄增加呈现一定的趋势，灌丛层生物多样性有所增加，草本层先增加后降低，均匀度变化不大，整体有所下降，而且林龄差异越大，物种的差异程度也变大。

Saw the green and luxuriant vegetation, they also look like are gripping the vigor, refuels for Beijing!

看到郁郁葱葱的植被，她们也像是攥着劲，为北京加油呢！

It is shown that the Loess Plateau might be regionalized into different vegetation zones of forest and steppe.

在阐述植被建造依据之后，本文讨论了植被建造的技术与模式，表明典型水土保持植物是建造水土保持植被的首选植物。

Water was diverted back into nearby wetlands that had been drained by farmers and suitable vegetation was replanted.

引水注入附近一度被农民抽乾的湿地，并且重新种植适当的植物。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
