Forests and jungles have thick vegetation. 森林和热带雨林中有茂密的植被。 vegetation 网络解释 1. 植被：我们可以认识如何在ModelBuilder环境下通过绘制数据处理流程图的方式实现空间分析过程的自动化,加深对地理建模过程的认识,对各种GIS分析工具的用途有深入的理解. 数据:矢量数据:研究区界线(Study Area)、植被(Vegetation),栅格数据:土壤类型栅格(Soilsgrid) 2. 赘生物：④ 赘生物(vegetation) 指发生在心瓣膜上的附壁血栓,常由血小板和纤维蛋白组成,实质为白色血栓.气体栓塞(gas embolism)包括空气栓塞和氮气栓塞.贫血性梗死(anemic infarction)主要是动脉阻塞的结果,常发生在组织结构比较致密和侧枝血管细而少的器官如脾, 3. 3. 植物：硫化氢系植物(vegetation)、土壤、死水(stagnant water)及动物排泄物中的硫酸盐(sulphate)经细菌分解后演变而来. 在大气中,它很容易被氧化成二氧化硫且经雨水带至地面. 在某些好氧性(aerobic)土壤中,特定的细菌将二氧化硫转换成硫酸盐. 4. 被：植物群落是由一定种类的植物在一定的生境条件下所构成的有机整体. 地球表面全部植物群落的集合,称为植被(vegetation). 植物群落是植被的基本单元,也是生物群落的重要组成成分. vegetation 双语例句 1. It is essential that the vegetation of this area should be preserved. 保护这一地区的植被是很必要的。 2. vegetation的反义词 2. It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation. 分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。 3. 3. The coverage of vegetation can prevent raindrop erosion, the humus layer from falling branches and leaves not only improve the chemical and physical condition of the soil but also improve the stability of soil aggregate, increase soil permeability, and reduce surface runoff, effectively prevent the soil erosion. 植物覆盖於地表可以避免雨滴打击地面，防止土壤冲蚀；枝掉所形成的腐植层可改善土壤的化性质，促进土壤团稳定，增加土壤渗透性并减少迳，有效抑制土壤冲刷；又植物根系的锚锭作用，可有效控制浅层崩塌的风险。 4. The soils of surface 0~5 cm and subsurface 5~25 cm were collected from selected eco-tesseras of degraded abandon lands, corn cultivated lands, vegetation recovery lands and well-protected vegetation lands respectively. Total pool of soil major nutrients showed sensitive changes with vegetation cover, accompanying a similar change of soil microbial biomass carbon. Vegetation recovery resulted in a remarkable change of soil total nutrient pool and increased soil microbial biomass carbon. However, vegetation recovery for 3~6 years long did not drive a significant change in available pool of the nutrients as well as the microbial respiration quotient and soil enzyme activities. 研究表明土壤养分库是土壤中微生物活性基础，微生物量碳随土壤养分库容的退化或恢复而相应变化，退化岩溶地植被恢复3～6年后，主要养分总库容得到明显恢复(恢复程度55%～65%)，因而带动了微生物量碳的恢复(平均恢复程度60%以上)，但养分的活性、微生物的功能(呼吸熵及土壤脲酶和磷酸酶活性)并没有得到相应程度的恢复(平均恢复程度仅在25%～40%)。 5. 5.
