作者： ANAMiKA Avni PRADEEP chaudhry Department of Chemistry MCM DAV College indian institute of Forest Management

Urban greenery generates significant ecosystem services and contributes to improving environmental quality, quality of life, and sustainable urban development. Research on various aspects of urban forestry such as carbon sequestration, removing air pollutants, reducing noise, providing recreational amenity benefits is in infancy stage in india. This paper reviews some significant studies in the field of air pollution removal by urban vegetation in developed and developing countries including india. Some issues related to development and research in the field of urban greenery and future management strategies to be adopted in india have been discussed in the paper.

土壤与耕作部件间的相互作用规律是设计和选用土壤耕作部件的基础。研究土壤和耕作部件间的相互作用规律就是要研究耕作部件对土壤产生的作用和它们之间的作用力,首先必须探讨耕作部件工作时土壤运动规律和施加于土壤的作用力。为此本文建立基于离散元方法的旋耕工作模型;对比分析实验与仿真的土壤位移:在土槽实验中采用示踪块方法测量土壤位移,仿真中通过追踪表层土壤颗粒的运动获得仿真位移;利用实验和仿真数据对土壤位移和运动机理进行分析。结果表明:土壤水平和侧向位移都随着转速增加呈现增加的趋势;土壤的水平运动位移总是大于同转速下的侧向位移。浅层土壤颗粒的运动位移最大,中层土壤次之,深层土壤最小。较深位置的土壤,距离旋转中心越近的土壤颗粒水平位移和侧向位移越大。在旋耕刀切土范围内的土壤,有向相反方向运动趋势的浅、中、深层颗粒比例分别为26.2%、72.1%、48.4%。在水平力作用下,大部分土壤颗粒随着旋耕刀切土有向后运动的行为;土壤在开始时刻的侧向受力和侧向运动方向,由颗粒的侧向位置是否偏离侧切刃轴线决定,位于侧切刃轴线左侧的颗粒,则其侧向力向左,反之亦然;土壤在垂直方向先随着刀具入土向下运动,然后滑出刀刃边界被抛起。本文建立的仿真模型得到的土壤水平位移和侧向位移与相应实验值的误差为24.9%和15.3%。本文运用离散元法进行旋耕过程中土壤宏观和细观运动行为的分析,有助于理解旋耕刀与土壤的相互作用机理,为旋耕机械的设计与优化提供理论依据。
