And the main plantation tree species should select fast growth timber and economically high efficiency species, such as poplar, peach etc.

造林树种可选择速生丰产的杨树等用材树种和经济效益高的桃树等果树。

Leaf morphological and physiological acclimation to three irradiance levels (5 %, 25 % and 50 % daylight) were investigated in seedlings of the following four tropical rainforest tree species. Macaranga denticulata and Paravallaris macrophylla are light-demanding species, and Myristica yunnanensis and Garcinia paucinervis are shade-tolerant species.

摘 要 ：研究了西双版纳热带雨林 2 种喜光树种中平树、倒樱木和 2 种耐荫树种云南肉豆蔻、金丝李幼苗叶片光合和形态解剖特征对 3 种不同生长光强（ 5 %， 25 %和 50 %相对光强）的适应。

On the basis of investigating resources of economic forest, the study using the different of distribution area and the restriction as principle, apply the method of comparison and analysis to compare and analyze the leading factors of where every tree species distributes, its biological character istle and ecological distribution habits.

本研究在资源现状调查基础上，以地域分异和主导因子制约为原则，采用分析对比的方法。将各树种主产区气象因子和树种自身的生物学特性及生态习性进行对比分析，制定相应的气候适宜性评价指标体系，对我省87个县市的气候条件进行打分。

When we start a landscape design of expressway from Xichang to Panzhihua , the first, Dodonaea viscosa, Lantana camara, Jatropha curcascim were chosen, which had such characteristics as adapting reginonal climate, corresponding with purpose of restoration, and self-renewal, whose maintenance and investment were lower.

在进行西攀高速公路绿化景观设计时，优选出适合当地气候、符合恢复目标、在路域附近的植物群落具有自我更新能力、养护成本较低的植物有车桑子、五色梅、小桐子，它们能够与环境协同进化；由外地引进的树种如新银合欢、台湾相思经造林实践检验有更广泛的适应性，作为先锋树种是适宜的；从光合特性测定值比较五色梅、棕榈、加杨、香樟、赤桉、丝兰、石榴水分利用效率较高，其个体生态特性表现出较强的耐干旱能力。

Ornamental trees and shrubs, especially those with colored leaves are worthy to be enjoyed, they have many characteristic features superior to herbage and other ligneous plant.

观叶树种尤其是某些色叶树种观赏价值较高，具有许多草本植物和其它木本植物所不具备的特点。

The methods of computing for similar coefficient were Discriminance of Minimal Difference of Parameters, Discriminance of Limen of Tree Compositive Character and Synthetic Weight Similarity of Parameters. The contribution of all parameters were considering as same for DMDP and DLTC, but it estimate s the similarity between parameters according to the limen for DLTC. DMDP was based on the principal component analysis for wood transverse section micrograph characters and computing the similar coefficient according to the contribution of every parameter.

其中最小差值差数判别法与树种综合特征阈值法是将每个特征参数对木材横切面显微图像特征的贡献率视为一致，只是树种综合特征阈值法是以阈值的大小来判断特征的相似性，而综合加权相似法是建立在对木材横切面显微图像特征参数的主成分分析的基础上，根据每个特征参数的贡献率大小计算相似系数。

Liriodendron Chinese is a superior virescence forestation specie, also a paper pulp-making and veneer-making specie in south China.

马褂木是我国南方优良的造林绿化树种，也是山地丘陵地区优先发展的纸浆纤维材和胶合板用材树种。

Based on intensive observation and measurement to the characteristics of tissue anatomical structure of some tree species, the relation of anatomical structure of tree species and their resistance to longicorn beetles was studied systematically with stepwise regression analysis.

Zhu Bai (the agrestic tree that Podocarpus Nagi) is the Fujian Province is planted, seminal bead is big, kind solid oil content 37.22% above, unit area is planted real yield is high, as fuel oil the tree is planted have wide development perspective.

竹柏是福建省的乡土树种，种子粒大，种实含油率37.22%以上，单位面积种实产量高，作为燃料油树种具有广阔的发展前景。

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。
