雨林

Growing disdain among consumers for water packaged in plastic has hit sales of Vittel, Perrier and Poland Spring while many of Nestlé's competitors - most recently Cadbury and Mars - are signing up to certification schemes such as Fairtrade and Rainforest Alliance.

消费者对塑料包装饮用水越来越反感，已经影响了Vittel、巴黎水和波兰泉的销售。另一方面，雀巢的许多竞争对手都签署了公平贸易和雨林联盟之类的认证计划，最近的就有吉百利和玛氏。

While in the 49th US state, you'll have plenty of opportunities to participate in excursions, including dogsled adventures, rainforest canopy and zip line exploits, whale encounters and wilderness kayaking.

而在第49届美国各州，你将会有很多机会参与游览，包括狗拉雪橇冒险，雨林的机盖和笼头攻击，遇到鲸鱼和荒野皮艇。

What Debbie enjoyed to the point of obsession was a video of the Amazonian rainforest. It seemed to stir an atavistic chord in her stout breast.

真正让黛比着迷的是那盒亚马逊雨林的录相带，它令黛比那强壮的身躯里渴望回归家园的心激荡不已。

The seedlings of 4 dominant tree species of tropical seasonal rain forest, such as Pometia tomentosa, Barringtonia macrostachya, Myristica yunnanensis and Knema globularia, were transplanted at three altitudinal sites (low 600 m in Menglun; middle 1 100 m in Caiyanghe; high 1 600 m in Mengsong) in Xishuangbanna. The parameters of photosynthesis and biomass of these seedlings were measured. The results showed that the low temperature at high altitude caused dormancy or photosynthetic system destroy.

在云南西双版纳勐仑(600 m，低海拔)、菜阳河(1 100 m，中海拔)和勐宋(1 600 m，高海拔)，对热带季节雨林4种主要树种绒毛番龙眼、云南玉蕊、云南肉豆蔻和小叶红光树幼苗进行移栽试验，测定幼苗的光合作用和生物量。

Is a perennial herbaceous plant in the family Cactaceae originated from the rainforest in tropic America. In Taiwan, there are about 1000-ha pitaya plantation mainly in the middle and southwestern areas.

原产热带美洲雨林，属仙人掌科三角柱属多年生攀缘性肉质植物，喜高温多湿之气候，目前全台栽培面积近1000公顷，产区主要集中在中南部，为国内重要的新兴水果。

The forest is composed mainly of the families, Rubiaceae, Myrtaceae, Myristicaceae, Lauraceae and Euphorbiaceae, and dominated by tree species, Metadina trichotoma, Syzygium cathayense, Knema erratica and Paramichelia baillonii. In physiognomy, the forest is characterized by the trees with mesophyllous, entire and leathery leaves. Woody lianas are found dominant, but trees with buttresses and cauliflory are relatively few in the forest.

结果显示，勐养山地雨林主要由茜草科、桃金娘科、肉豆寇科、樟科、大戟科等植物种类组成，以黄棉木、华夏蒲桃、假广子及山桂花为乔木优势种；群落乔木层以中叶、全缘、革质、尾尖、常绿植物占优势，灌草层植物则以中叶、全缘、纸质叶植物为主；藤本植物中以木质藤本占优势，板根和茎花现象少见。

Vatica guangxiensis and Altingia andersonii are dominant tree species of the upper layer in the community, which can be divided into A, B, C, D, E layers. and is mainly charactered by evergreen megaphaenerophytes and mesophaenerophytes with simple, chartaceous, entire, caudal mesophyll leaves. There are a lot of wooden lianas and epiphytes between layers.

该群落是以龙脑香科的广西青梅和金缕梅科的细青皮为乔木上层优势树种，群落分A至E层，外貌以单叶、纸质、全缘、尾尖、中叶为主的常绿大、中高位芽植物组成为特征，层间木质藤本和附生植物丰富，属热带季节雨林。

The model indicated that the region's central rainforests were more stable climatically than the southern forests, going back as far as 21,000 years.

模型显示：追溯过去的21000年，这一地区中心的雨林比南部的森林有更大的气候稳定性。

Biomass in the rain forest was far more than that in the plantation of 12 years,especially for the shrub layer.But the biomass of litterfall collected in the plantation was greater than that of the rain forest for the reason that Betula alnoidis defoliated in dry seasons.9 Four years observation found that soil bulk density tended to increase first, then decrease after planting trees;total soil porosity and non-capillary porosity tended to decrease and after few years they recovered to different degrees;the soil cation exchange capacity for all forest types increased;in the soil of 0-30cm depth,soil salt saturation tended to decrease;nutrient content in the soil of 0-60cm depth in the young stand tended to decline;soil effective P,effective K and N contents all tended to decrease.

山地雨林的总生物量远远大于10年生的西南桦人工林，其中灌木层的相对差别尤其巨大。94次的观测发现，人工林栽植后，土壤容重一般呈现一个先上升后下降的特点；而土壤非毛管孔隙度、土壤总孔隙度大多呈下降趋势，几年后有不同程度的恢复。

The plantation defoliated in dry seasons while the mountain rain forest was tall and dense evergreen broadleaved forest and kept green in dry season.The mountain rain forest\'s arbor layer contained 3 layers.Relatively open space under the canopy,rare shrub,sparse grasses,very tall wood vines and rich epiphytes were found in it.4 Afforestation did not change the life form spectrum significantly.

西南桦人工林的乔木层在旱季落叶，而山地雨林外貌为高大、常绿、茂密的阔叶林，即使旱季也仍保持林冠葱绿的外貌，乔木层可明显的分为3层，林下比较空旷，灌木植被少见，草本植物分散，另外具有高大的木质藤本植物和附生植物。4人工造林对群落的物种生活型谱影响不大。

I urge any American living outside the country to get an early start checking his/her registration and receiving an absentee ballot, because it can take a while.

我奉劝身在国外的所有美国人早点着手核对登记表，并接收缺席选举人票，因为这得花点时间。
