查询词典 forest tree

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.

首先，经过对北京山区水源林天然林和人工林结构要素的演替动态研究，提出其发展规律，同时依据水源林结构与功能耦合关系研究，从林分层次和流域层次上分别构建了水源林的理想结构，其中，林分层次上水源林的理想结构为：异龄、复层、混交的结构状态，林分结构趋于天然林结构的特征；在流域层次上水源林的理想结构为也应形成&复层&、&异龄&、&混交&的结构，即：在流域各水源林斑块间形成林冠层复层、斑块内部乔木、灌木、草本层的复层；不同水源林年龄面积上的均匀分布；形成不同水源林斑块间的镶嵌分布。

The system implemented forest fire model selection automatically and intelligently. BP artificial neural network model of forest fire model selection was build by treating forest fire environment data as inputting variable and treating appropriate forest fire model as outputting variable. At the same time, we studied the methods of acquiring and calculating data of inputting and outputting. The system implemented machine of model selection automatically based on dynamic data driven technology. We selected 72 items experimental data from historical forest fire records in Beijing to experiment and confirm the validity of model selection. It turned out that the reliability of model selection is more than 80 percent.

3基于BP人工神经网络方法设计了林火模型适宜性选择技术框架结构，通过神经网络形成林火模型选择知识，实现了林火模型的自动化和智能化选择；以火场环境因子为输入变量，以适宜火场环境模拟的林火蔓延模型作为输出变量，构建了林火模型选择神经网络模型；研究了输入、输出因子数据的获取与计算方式，实现了动态数据驱动的林火模型自动选择机制；以本京市为例，选择了有详细火场情况记录的72场林火作为实验样本，其中60条记录作为学习样本集，12条记录作为验证样本，对神经网络进行了学习和验证，实验结果表明，模型选择精度可达到80%以上。

7Gm〓 in the 20 yr forest, 1139. 8gm〓 in the 80 yr forest and 912. 4 gm〓 in the climax forest, respectively. However, along with forest succession, the dominant tree species fine root annual production increases, whereas other arboreal and grass fine root annual production decreases.

白桦山杨幼林、白桦山杨成熟林与原始阔叶红松林中，细根年生长量分别为712.7gm〓、1139.8gm〓和912.4gm〓；但是，随着演替的进行，林地主要树种细根的年生产量会逐渐增加，其它木本和草本细根的年生产量则逐渐降低。

Cunninghamia Lanceolata showed that,after Cunninghamia Lanceolata sprout forest had been changed into Schima superba and Cunninghamia Lanceolata mixing forest,tree growth had largely been increased,and the water holding and conserving ability had been upgrated,as well as,the microclimate within forest had been improved,the forest land productivity had been protected.

木荷与杉木萌芽林混交试验，结果表明：杉木萌芽林改造为木荷杉木混交林后，林木生长量大幅度提高，林木和林地持水、保水能力增强，林内小气候得到改善，林分水源涵养能力进一步提高，林地生产力得到维护，为今后杉木多代萌芽林和杉木低产林改造提供科学依据。

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.

应用生育地因子评估树种之生态地位，能解决统计实证方法在空间异质性使用的限制，并可同时评估多种树种，因此可应用在造林树种之选择，亦可应用於崩塌地复育造林树种之选择，以及林相改良造林树种之选择，在收集更多树种属性与空间分布资料后，配合此评估方法，未来更可模拟出台湾森林之动态，以及评估环境变迁对台湾森林所造成的影响。

Tree and you to can't separate, tree can lack you, you could come and plant I this head already ruined death tree that has died soon only, I will fire the hope of growing again because of you,Water and earth forge tree , could let tree survive you, I the tree survive at only have youing, without you, my life is written in water, will you of today come?

树与你是不可分离，树不能缺少了你，只有你才能来栽种我这棵已快颓逝的死树，我会因为你而重燃生长的希望，水和大地锻造了树，却是你才能让树生存，我这棵树就只有拥有你时才能生存，没有了你，我的生命则为转瞬即逝，今天的你会来吗？

And so tree peony is the main economic support of the product area of tree peony .All of this need a systemic and scientific cognition of the rules of grow and development of tree peony. But as the study on the physiological and biochemical changes during the period of forming strong buds of tree peony is concerned, the level is very low and still use the traditional methods of cultivation and management . So if we want to get the quality flowers ,we should have quality buds and we should use all methods ,if we can , to meet the conditions that tree peony needs. And so it is very important for theory and practice to study the physiological and biochemical changes during the period of forming strong buds of tree peony.

但是，不论是生产商品苗木还是用于反季节催花，都需要对牡丹的生长发育规律有一个系统和科学的认识，然而，目前的牡丹栽培仍然衍用传统的栽培技术，对牡丹生长发育过程中的生理生化变化规律的认识，却还停留在比较肤浅的水平和层次上，因此要得到高质量的牡丹花，就要有高质量的牡丹芽，就必须按照牡丹的生长发育规律，建立科学的栽培技术体系，在牡丹壮芽形成过程中运用一切可以运用的栽培措施、管理技术来满足条件，因此，对牡丹壮芽形成过程中的生理生化变化的研究就具有十分重要的理论和实践意义。

Apple tree canker also called rotten skin disease ,which is one of main diseases of fruit tree plant in north, and its harm is extremely serious. Moreover, the scope is widespread and it exists from the sapling to the senile tree in different degree. Apple tree canker is the main reason of the dead shoot, the dead tree and destroying the garden ,which also blocked the development of the north of fruit tree seriously.
