It's necessary to have a simple and systematic digital model in thinning decision-making. In the paper, the tree location map of 150 m x 30 m Luanta-fir in Hui-Sun Forest Experimental Station were digitized in GIS and thinning simulation by random, Telathaki-Wadali-Chi, DBH class and crown competition index method.

本研究系利用GIS 配合林木位置图，以惠荪林场之150m x 30m 香杉采穗园为研究材料，以生产大径材为目的的考量下，针对疏伐木之选择，利用随机法、寺崎渡氏法、胸径级法、树冠指数法等四种方法加以模拟、评估、探讨。

The crown surface area was decreased with stand density and the relationship between crown volume and stand density was not significant.

林分树冠表面积和树冠体积预估模型的检验结果表明，两个模型的平均相对误差都在 8％之内，预估精度均大于91％，说明所建模型可以很好地预估樟子松人工林不同林分条件下的林木树冠表面积和树冠体积。

Forest structure,individual quality,tree density and crown density,and structure and function of brush forest are used to construct a criterion to the LQBF.

判定低质低效林的依据是林分的结构、林木个体质量、密度和郁闭度、灌木林结构和功能。

The models of whole leaf biomass of a tree and single branch based on stand and forest factors were established and the vertical distribution of leaf biomass in the crown was studied in this paper.

基于实测各树冠变量，同时建立了基于林木和林分测定因子的全树冠叶量和单个枝条着叶量的预估模型，并对树冠内叶量的空间垂直分布规律进行了研究。

Chuan Wangsheng shou from the first temple from west to east from the ditch grass ditch called a total distance of about 67 kilometers, along the wooded, Yamahana Kam-up, winding paths, a turn for the better, one stepzhen nai King, King King pleasant.

从第一川望圣寿寺由西向东而来的沟叫草沟，全长约六七公里，沿途林木茂盛，山花缀锦，峰回路转，柳暗花明，真乃一步一景，景景宜人。

There are about 18000 species, which include herbs, trees, shrubs, climbers, and some aquatics.

约1800余种，包括草本植物、林木、灌木、攀援植物以及一些水生植物。

Scatters the peninsula north west in Greek uncle Luo Benni the Elis city-state, some name is the Olympia the small place, the brook murmur, the forest onion, has a liking for does not have with the Greek other place what to be different.

在希腊伯罗奔尼撒半岛西南部的伊利斯城邦，有一个名叫奥林匹亚的小地方，溪流潺潺，林木葱茏，看上去与希腊别的地方没有什么不同。

For example, relation of sand soil water content and plant leaf water potential of shrub breeding or arbor breeding in the morning can be simulated using the followed exponential function:〓 or 〓, in which, coefficient value of a and b are different on different breedings or different field.

通过在毛乌素沙地、乌兰布和沙地、库布齐沙漠、巴丹吉林沙漠等近6年的测试资料的研究分析表明：①营造固沙林后，沙土中的含水率降低，降低的程度主要受到林分密度和造林后林木生长年限的影响。

Walk into the ghost town When you walk into the ghost town,you will find verdant trees, delicate buildings,temple carillons,temples,josses,and pavilions there are so wonderful.

4《走进鬼城》鬼城里林木苍翠，建筑精美，鼓磐时鸣，庙宇殿堂神像森罗，楼台亭阁依山而立。

Although forest insects and pathogens cause various detriments,they also make positive contributions to forest succession,material cycling and energy flow,a food source,creating wildlife habitat,etc.,and further,in an ecosystem perspective their contributions are critical to forest biodiversity,soil fertility and long-term forest health and sustainability,so forest managers must consider both the detrimental and beneficial functions of insects and pathogens.

森林昆虫和病原物虽然能引起林木损伤与死亡，但它们在森林演替、物质循环和能量流动、食物来源、创造野生动物生境等方面都作出了积极的贡献，而且在一个生态系统发展前景中，对于森林生物多样性、土壤肥力、森林的长时期健康和稳定性等方面，它们的促成作用也是必不可少的。因此，森林经营者应当考虑昆虫和病原物的害与益的两方面作用。

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。
