查询词典 forestry

The existing image matching methods work well in open areas with relatively smooth terrain. However, they still meet many problems in the case of larger scale images of nature, especially in the dense city centers, forestry areas and the textureless regions such as water bodies. The reliability of image matching is still a big issue in these cases. For example, the corners of buildings and some object boundary points sometimes cannot be matched successfully, and there are many blunders in the automatically derived digital surface models that need to be manually removed, which leads to the decrease of the automaticity in digital photogrammetry.

现有大多数立体影像匹配方法对于地形平滑的开阔地带具有较高的可靠性，然而，面对从千变万化的自然界所摄取的影像，现有的匹配方法仍然存在许多问题，尤其是在植被茂密、建筑物密集和水域等区域，影像匹配的可靠性还不高，一些建筑物的角点和地物的主要边界点还不能正确地匹配出来，自动生成的数字表面模型中存在着许多异常值，需要进行大量的人工编辑处理，这在很大程度上制约了数字摄影测量自动化水平的提高。

Yuan yang county holds the good opportunity when our country carries out the developing of Western area and the changing of tillable field to forestry, makes sure the development strategy of "strong state with Green Economy" should building and puts the main point on the river valley of Red River which is a dry and hot area. So from 2000 year, it starts to grow Azadriachtaindiceae.

中文摘要：红河州元阳县抓住国家实施西部大开发和退耕还林的极好机遇，认真贯彻落实&绿色经济强州&的发展战略，加快以红河河谷为重点的干热河谷生态环境建设步伐，从2000年开始种植印楝。

Effect of returning hill terraced fields for farming to forestry and grass were surveyed based on fixed point observation for nine years continuously. The results showed that death rate of Popular cathayana, Ulmus pumila and Hippophae rhamnoides was 100%, 92% and 12.7% respectively in terraced fields.

通过对湟源地区阴坡梯田退耕还林还草工程连续9年样区定点观测，结果表明，在梯田栽植的杨树到第9年100%死亡，榆树的成活率只有8%，沙棘的成活率为87.3%，柠条的成活率达100%，但长势不旺。

The injury tolerance of cell plasma membrane and the correlative enzymes activities of plasma-membrane protection system in the Ulmus pumila leaves treated by nine concentrations (0.3%, 0.6%, 0.9%. 1.2%, 1.5%, 1.8%, 2.1%, 2.4%, 3.0%) of Na2CO3 and NaHCO3 mixtures were studied in a greenhouse of Northeast Forestry University, Harbin, China.

在东北林业大学育种基地，利用9种浓度(0.3%、06%、0.9%、1.2%、1.5%、1.8%、2.1%、2.4%、3.0%)的Na2CO3和NaHCO3混合液对白榆扦插苗进行胁迫处理，探讨其在盐胁迫下，细胞质膜的伤害程度和质膜保护系统相关酶的活性。

According to the "Waterbirds Species List" published by the State Forestry Bureau in 2003,the waterbirds in 8 zoogeographical prefectures and 4 zoogeographical provinces in Shaanxi Province were counted,and the community similarity indices between each zoogeographical prefecture and zoogeographical province were figured out.

河流众多的关中平原省的渭河谷地平原州的水鸟种类最多，有85种，水鸟最少的是干旱的黄土高原省的南部黄土塬土石山地梢林州，仅有23种；群落相似性指数最高的是相邻的黄土塬土石山地梢林州和渭北台塬州。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。
