  • Compositional dynamics of plant functional groups and their effects on stability of community anpp during 17 yr of mowing succession on leymus chinensis steppe of inner mongolia , china
    内蒙古羊草草原17年刈割演替过程中功能群组成动态及其对群落净初级生产力稳定性的影响
  • The conventional culture - dependent method and culture - independent 16s rdna analysis method were used to investigate the nembure of some soil microbial groups and the bacterial community
    同时采用分离培养与不依赖于培养的16srdna分析的方法研究了有机磷农药长期污染对主要土壤微生物生理功能群数量和微生物群落结构的影响。
  • With the increase of abandoned time , perennial plants increased , the function communities were richer , p diversity index in two communities reduced with abandoned interval , but the vegetation restoration was slow , the land abandoned for 30 years have not got to climax community
    随撂荒年限的增加,多年生植物的种类和数量逐渐增加,植物群落功能群构成逐渐丰富,群落间多样性指数随撂荒时间间隔的增大而逐渐减小。但植被恢复缓慢,撂荒30年仍未达到顶极群落阶段。
  • The results indicated that as the intensity of sward cleavage increased , elymus nutans and other plants that had high requirements in soil aeration and resource space presented an increased competitive edge and the species that had low requirements in soil aeration and resource space presented an opposite picture ; low - intensity sward cleavage could help increase species diversity to a certain extent , but the diversity index appeared to decline as a whole as the cleavage intensity increased ; the effects of sward cleavage on functional groups of the vegetations showed in such manner as e . nutans - represented grasses increased in their composition with the intensity of sward cleavage raised , and sedges and forbs decreased in their compositions with the intensity of sward cleavage raised ; sward cleavage showed a significant improving effect on primary productivity of the meadows and was capable of increasing the proportion of quality - grass biomass to the total plant biomass ; sward cleavage could be independently employed as an effective measure to rehabilitate and improve alpine - meadow grasslands and thus played a basic and key role in the technical combination aiming at establishing hay fields characterized by e . nutans
    结果表明:垂穗披碱草等对土壤通透性和资源空间要求较高的物种,竞争力随划破强度的增加而上升,而对土壤通透性和资源空间要求相对较低的物种则相反;轻度划破干扰对提高物种丰富度具有一定的促进作用,但多样性指数则总体上表现为随划破强度的增加而呈下降的趋势;划破干扰对植被功能群的影响表现为以垂穗披碱草为代表的禾草类组分随干扰强度的增加而显著上升,莎草类和杂类草组分随干扰强度的增加而显著下降;划破干扰对草地初级生产力的提升具有显著的促进作用,且可显著增加植物总量中优质牧草的比重;划破干扰可独立作为高寒草甸类草地恢复与改良的有效措施,在定向培育垂穗披碱草型割草场的技术组合中具有核心和基础性的地位。
  • This text introduces the characteristic concept of turbine control system from two traditional aspects of static and dynamic state , and the characteristics of reheating system and the power - frequency electric liquid control system , and analyzes the difference from the simulated electric control system to digital electric system . this text describes the constitute of deh system from three aspects and analyzes the reliability of deh system
    本文从传统的汽轮机静态特性和动态特性两个方面讲述了汽轮机调节特性的概念,以及中间再热式汽轮机调节特性、功率? ?频率电液调节系统的特点。以阳泉二电厂deh系统为例,从硬件、软件和控制功能群三部分叙述分析了deh的组成和各部分作用,并对deh系统的可靠性进行了分析。
