林木

Care of the scenic mountains behind, circle around a low slope, rocks covered with a groove between the poor level of thickness, the wild mix of trees, vegetation cover more than 80%, there is pheasant in the mountains, mountain rabbit, wild animals, such as short-tailed pheasants.

该景区身后高山呵护，左右低坡回环，山石沟贫间长满了高低粗细、千姿百态的野生林木，植被覆盖率达80%以上，山林中有野鸡、山兔、短尾雉等野生动物。

Through observation and study,the optimum designing programs are showed as follows:the cross degree between shelter belt and do minant wind direction should be more than 45 degree,the main forest belt distance should be from 150 meter to 200 meter,the sub belt distance should be from 230 meter to 700 meter,the best belt structure is sparse and transparent structure.

通过观测和研究，得出风沙区农田防护林带的走向与主风方向的交角，不能小于 45°，主林带间距 15 0m——— 2 0 0m ，副林带间距 2 3 0m——— 70 0m ，林带结构以疏透结构为最好，主林带一般由主林木 5— 6行组成，副林带由 2— 3行组成，再在迎风面和背风面配置 1行— 2行灌木和针叶

According to thefunction, the conclusions for L.olgensis and C.lanceolata are asfollows:1CCF＜200,showing growth with constant tree number;2200≤CCF≤300 transition from growth with constant tree number to theself-thinning,in other words,the change of SDI can be described aslinear combination between the growth with constant tree number andthe self-thinning;3CCF＞300,growth in the self-thinning.

建立了CCF与林分密度指数和单位面积林木株数之间的函数关系式，并对长白落叶松和杉木得出：(1)CCF＜200。林分为等株数生长：(2)200≤CCF≤300时。为等株数生长向自然稀疏生长的过渡期，该期间林分密度指数的变化可用等株数生长和自然稀疏生长的线性组合来表达：(3)CCF＞300时，林分为完全的自然稀疏生长

The technology of seed storage and seed treatment is one of the key technologies in forest tree introduction.

种子贮藏技术和种子处理技术是林木引种工作中最为关键的技术之一。

Seeing elders with trunks seven feet wide, or walking through stands of the tallest trees here—gigantic Norway spruce, shaggy as Methuselah—should seem as exotic as the Amazon or Antarctica to someone raised among the comparatively puny, second-growth woodlands found throughout the Northern Hemisphere.

看着老树七英尺宽的树干，走在最高的林木之间——巨人般的挪威云杉，它们像玛士撒拉1一样饱经岁月的风霜——对于那些在北半球随处可见、较为低矮的次生林地中长大的人而言，这里本该如同亚马逊流域或南极洲一样让人惊艳。

In the distance in front, on the coast of that sea of mist, rose up the wooded hills, on which the enemy's army should have been, and something could be descried there.

远前方，雾海的彼岸可以望见林木茂盛的山岗，敌军想必驻扎在这几座山岗上，不知道是什么东西隐约可见。

Fishes Tingxiu Feng Shan, the evergreen pine and cypress; Peacock lake surrounded by mountains, sea embedded implicit Date;-long state tourism has a clear head net sand, shady trees, known as "North Jiangnan", tourism, vacation, the ideal of convalescence Paradise.

鳌鱼山一峰挺秀，松柏常青；孔雀湖群山环抱，嵌隐枣海；龙州旅游区水清沙净，林木成荫，被誉为&北国江南&，是旅游、度假、疗养的理想乐园。

I formed a beautiful picture in my mind: In the lofty mountains covered with dense forest, a handsome boy with leg wrappings, wearing a jacket made of animal skin and shouldering a hunting-gun, was running with a hunting dog after a wounded river deer, whose stumbling steps were set against the white cloud in the blue sky in sharp contrast to the strong and vigorous image of the boy----the boy was none other than myself.

当时，我的脑海里勾勒出了一幅美妙的图画：林木茂盛的崇山峻岭中，一个扎着绑腿、身穿兽皮背心、肩扛猎枪、手牵撵山狗的英俊少年，正在追赶一只已经被射伤的獐子，獐子踉踉跄跄的步态和少年骄健的身形，映衬在蓝天白云之间——这少年不是别人，就是我。

Before the construction of reservoirs, where fish jump, the two sides rice flower fragrance and lush forests, scenic beauty, be called Saibei "small Jiangnan."
