采伐

Illegal logging and usage of certified lumber is a key concern. China must be able to supply FSC certified parquet as soon as possible.

另外，非法采伐和认证木材的使用是一个重要的问题，中国应该尽快提供 FSC 认证的地板。

His father was a Presbyterian minister,and his early poems were hymns.

这棵树的树干和枝叶是由风暴和采伐共同造成的。

Then if you harvest the timber in year 1, it has a net present value of $58,500

那么如果你在第1年采伐木材，它的净现值为$58，500

The country has Been prodigal of its forests.

这个国家的森林正受过度的采伐。

However, many stands of trees are harvested only for pulpwood without regard to timber production.

然后，有许多林木仅仅是为生产纸浆采伐的，没有考虑生产木材。

There was a significant quadratic correlation between the mean soil respiration of litter layer and cutting intensity.

枯枝落叶层呼吸速率均值与采伐强度间存在显著的相关关系。

By comparing the similarity of grasshoppers' community in different habitat regions and clustering and PCA analyzing, the different habitat regions could be divided into 3 types: far off lake region including cutting blank and farmland region; near Lake Region including artificial larch tree and lakefront wetland; mountain site including crude redeposit broad-leaf weed-tree forest.

通过比较不同生境蝗虫群落的相似性，并经聚类和PCA分析，可将松花湖库区5种生境划分为三大类型，分别为远湖区生境，包括采伐迹地和农田；近湖区生境，包括湖边湿地和人工落叶松林；山地森林生境，主要是天然次生阔叶杂木林。

According to the character of vegetations and geography, Songhua lake Nature Reserve was divided into five kinds of habitats, artificial larch tree, cutting blank, lakefront wetland, farmland region, crude redeposit broad leaf weed tree forest.

根据植被和地形地貌特点，作者将松花湖库区划分为五种生境，即人工落叶松林、采伐迹地、湖边湿地、农田和天然次生阔叶杂木林。

Using a variety of diversity indexes to study the diversity of grasshopper in different habitat region, the results showed that diversity indexof 5 kinds of habitats has the order: crude redeposit broad-leaf weed-tree forest＞farmland region＞artificial larch tree＞lakefront wetland＞cutting blank.

采用各种多样性指数对不同生境蝗虫多样性进行了研究，结果显示，Shannon-wiener多样性指数的排序情况为天然次生阔叶杂木林＞农田＞人工林＞湖边湿地＞采伐迹地，Pielou均匀度指数变化和H′变化较为一致，相关系数为0.918，达到了显著性水平。

The farmer can work alone in the field or the woods all day, hoeing or chopping, and not feel lonesome, because he is employed; but when he comes home at night he cannot sit down in a room alone, at the mercy of his thoughts, but must be where he can "see the folks," and recreate, and, as he thinks, remunerate himself for his day's solitude; and hence he wonders how the student can sit alone in the house all night and most of the day without ennui and "the blues"; but he does not realize that the student, though in the house, is still at work in his field, and chopping in his woods, as the farmer in his, and in turn seeks the same recreation and society that the latter does,though it may be a more condensed form of it.

农夫可以一整天，独个儿地在田地上，在森林中工作，耕地或砍伐，却不觉得寂寞，因为他有工作；可是到晚上，他回到家里，却不能独自在室内沉思，而必须到"看得见他那里的人"的地方去消遣一下，用他的想法，是用以补偿他一天的寂寞；因此他很奇怪，为什么学生们能整日整夜坐在室内不觉得无聊与"忧郁"；可是他不明白虽然学生在室内，却在他的田地上工作，在他的森林中采伐，像农夫在田地或森林中一样，过后学生也要找消遣，也要社交，尽管那形式可能更加凝炼些。

Do you know, i need you to come back
