It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。

Regardless of the kind of competition, lotus leaf fern Adiantum in 5400 lux light intensity, 60 percent of soil moisture conditions, the total biomass of the largest, which also shows a lotus leaf fern Adiantum more to live in this habitat, but In such a habitat, the species of lotus leaf fern Adiantum competition among the lowest relative intensity, but these habitats and less dispersed.

无论有无种内竞争，荷叶铁线蕨在5400lux光照强度，60%土壤含水量的环境条件下，总生物量最大，这也说明了荷叶铁线蕨更适应生活在这个生境中，但是在这种生境，荷叶铁线蕨的种间竞争相对作用强度最低，而且这些生境少并分散。

This study will be mainly through potted lotus leaf fern Adiantum seedlings and wire division to transplant fern, and then through the different light intensity and moisture content of the orthogonal to quantitative research lotus leaf fern Adiantum optimum growing conditions, and through Transplant Research Laboratory test pilot of the two species, competition between species to find lotus leaf fern Adiantum way to protect endangered mechanism and provide a theoretical basis.

本研究主要通过盆栽将荷叶铁线蕨的幼苗与铁线蕨进行分株移植，再通过在不同光照强度和水分含量的正交实验来定量研究荷叶铁线蕨最适生长条件，并且通过实验室移栽试试验探究两物种之的种内，种间竞争关系为寻找荷叶铁线蕨濒危机理和保护途径提供理论依据。

The "Prufer" code of such a tree is built as follows: the leaf (a vertex that is incident to only one edge) with the minimal number is taken. This leaf, together with its incident edge is removed from the graph, while the number of the vertex that was adjacent to the leaf is written down.

从题目描述我们可以知道，对于一棵树，每次都找到编号最小的叶子结点，然后输出它的双亲结点的编号作为 Prufer Code，同时删除这个最小的叶子结点为下一次输出 Prufer Code 做准备。

Studies on the autointoxication of Chinese fir show that the aqueous extracts of surface soil, leaf litter, half decaying leaf litter, fresh leaf, branch, bark and root in pure Chinese fir plantation and their polyvinyl pyrrolidone k30 solutions affected the seed germination of Chinese fir, Raphanus sativous and water convolvulus.

对杉木自毒作用研究表明，杉木纯林中的土壤、枯落叶、半分解枯落叶和杉木鲜叶、枝条、树皮、树根的水浸液及其添加乙烯吡咯啉酮k30 的溶液对杉木种子、空心菜种子和萝卜种子的萌发均有影响。

If does not have the leaf leaving, the tree possibly to the presentcannot know leaf position which occupies in his heart, possiblyforever could not know the bo tree leaf not to be equal to has lostthe entire world.

如果没有叶的离开，树可能到现在也不会知道叶子在他心中所占的位置，可能永远也不会知道树没有了叶子等于失去了整个世界。

Result The scale leaf formation was inhibited by MeJA, the higher the concentration of MeJA the more efficient for restraining scale leaf growth. 100.0% of bulblet formation was obtained in the treatment of 1.0 μmol/L MeJA, but the scale leaf growth was significantly lower than control. 3.0 μmol/L MeJA had the inhibitory effect to both the bulblets and the scale leaves.

结果］茉莉酸甲酯对"Mona"试管百合鳞片叶生长有抑制作用，浓度越高其效果越明显；当茉莉酸甲酯浓度为1.0μmol/L时，鳞片叶发生率(87.9%)明显低于对照(100.0%)，但鳞茎分化和生长也显著好于对照；但茉莉酸甲酯浓度超过3.0μmol/L时，不仅对鳞片叶而且对鳞茎生长也有抑制效果。
