查询词典 vegetation

Based on Geographic Information System, the vegetation NPP is evaluated by integrating multi-temporal remote sensing information, meteorologic data, and ecological information in the North China Plain.

研究中运用多时相的遥感信息和气象资料，在地理信息系统的支持下，综合生态学信息开展了华北平原植被净第一性生产力研究。

At 4 km distance the species composition of different ecosystem components (vegetation, insects, birds, soil microbiota) had changed and the growth of trees was retarded.

在不同的生态系组分的4公里距离(植被、昆虫、鸟，土壤microbiota)树种组成改变了和树成长被减速了。

As a result of its high capability in interception of precipitation and enhanced evaporation of soil surface, the development of microbiotic crusts will more and more threaten the soil water condition which the artificial sand-fixing vegetation should rely on.

微生物结皮的逐年发育使其对降水的拦截能力和地表的蒸发能力都逐渐提高，并改变了水分在土壤剖面中的分配过程和格局，这对人工固沙植被赖以生存的土壤水环境产生了越来越大的威胁。

Microbiotic crusts had a high capacity of evaporation than the shifting sand dunes. During the evaporation process of one week after rainfall, the total evaporation in artificial vegetation regions constructed in 1956, 1964, and 1981 were 6.05, 4.99 and 4.23 times respectively as the total evaporation in shifting sand dunes.

微生物结皮有着比流沙区更高的蒸发能力，在雨后一周的蒸发过程中，1956、1964和1981年人工植被区的总蒸发量分别是流沙区总蒸发量的6.05、4.99和4.23倍。

The surveyed results show that as compared to the uncovered vegetation area, the existence of soil microbiotic crusts in the Tengger Desert region significantly increases the diversity and abundance of insect species, especially the diversity and abundance in the quadrats mainly covered by moss and lichen crusts are significantly higher than those in the quadrats mainly covered by cyanobacteria and algal crusts.

结果表明：与无结皮覆盖的植被区相比，生物土壤结皮在地表的覆盖显著地增加了昆虫的多样性和种的丰富度，其中以苔藓和地衣为主的结皮覆盖的植被样方中昆虫种的多样性和丰富度显著地高于以蓝藻和藻类为主的结皮样方。

In this study, with the psammophilous Caragana Korshinskii-Artemisia ordosica communities on semifixed dunes and fixed dunes in Shapotou region at the southeastern fringe of the Tengger Desert as the observation sample plots, the survey quadrats were arranged in the vegetation community areas with different types and coverages of soil microbiotic crusts.

本文以腾格里沙漠东南缘的沙坡头地区半固定沙丘柠条一油蒿群落和固定沙丘柠条一油蒿群落为观测样地，选择具有不同类型生物土壤结皮分布的植被群落为观测样方。

Taking forest edge as a central point,microclimatic information were recorded in transects from the open to the interior of three tropical dry seasonal rainforest fragments and a continuous forest of the same vegetation type in Xishuangbanna,Yunnan province,aiming at studying the horizontal gradient distribution of microclimatic elements near the edges.

本文以林缘为中心，研究了西双版纳地区3个热带干性季节性雨林片断和1个同样植被类型的连续森林林内至林外样带上小气候要素水平梯度分布。

Using the Landsat Thematic Mapper data and the measured grass yield data,the monadic linear regression models and the non\|linear regression models were established,to express the relations between grassland biomass and the different vegetation indices.

通过陆地卫星TM遥感影像数据和同期野外调查数据，分析了植被指数与草地植被生物量之间的相关关系，建立了不同植被指数与草地生物量之间的一元线性回归模型和非线性回归模型。

Monorchis belonging to Orchidaceae had a narrower one, indicating that rare and endangered Orchidaceae plants had a less distribution in Beijing mountainous region, and only distributed in several types of forest vegetation communities. Due to the lack of suitable habits, these herbage species were in dire need of prior conservation.

结果表明：野大豆的生态位宽度值较大，为0.297；大花杓兰、沼兰和角盘兰同属于兰科植物，生态位宽度值较小，说明兰科植物在北京地区分布较少，并且仅在几种森林群落类型中有分布，适宜生存的生境较少，急需优先保护。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."
