随着我国航空运输业的不断发展,全国机场布局规划的不断完善,机场建设项目近年不断增多,飞机噪声污染已经成为各城市日益严重的环境问题,目前,通过机场噪声的预测和评价,根据预测结果对机场周边敏感保护目标采取措施,改变和优化机场周边土地利用规划,是解决机场噪声问题的最有效方式,因此确保机场噪声预测准确性显得尤为重要。本文主要对我国机场噪声评价现状和评价指标进行了介绍,重点对机场噪声影响评价技术方法进行了论述,结合FAA(美国联邦航空局)开发的机场噪声模型inm(综合噪声模型)对影响机场噪声预测的各种因素进行了详细分析,分别研究了机型组合、起降方向、航班时刻安排、地形条件、飞行程序等多种因素对机场噪声程度和分布范围的影响分析,为机场噪声预测技术的进一步发展奠定了一定的基础。

飞机噪声对机场周围社区的污染是航空环境工程领域的重要问题,限制飞机最大起飞重量(MTOW)或合理规划机场周围社区已成为降低飞机噪声对机场社区噪声污染的2种主要途径。为了实现这2种途径从定性分析向定量研究的转化,对飞机噪声等值线面积与测量点上声暴露级(SEL)之间的准确关系进行了研究。以飞机离场为例,建立了等值线面积与测量点上声暴露级之间关系数学分析模型,利用inm计算的42种机型等值线面积和声暴露级数据,进行了所建模型的合理性和等值线面积与声暴露级之间线性相关性的有效性的验证,得到声暴露级减低1 d B对给定值等值线面积减小的程度或等值线面积按比例减小对噪声级减低的大小。从而为机场周围社区飞机噪声污染定量化控制开辟了新的方法。

The yield parameters and cost economics of Withania somnifera were studied using Integrated Nutrient Management (inm) treatments. Withania somnifera is cultivated in around 10,780 ha with a production of 8429 tones in India. The annual demand of this herb increased from 7028 tones (2001-2002) to 9127 tones (2004-2005). The field experiment was conducted at the research farm of Department of Plant Physiology, College of Agriculture, Jabalpur during Kharif season of 2008-2009 (1st year) and 2009-2010 (2nd year), whereas the laboratory work was carried out in Quality Laboratory, College of Agriculture, Jabalpur. The soil of experimental field was sandy loam in texture with pH 7.5, EC 0.18 dsm-1 having good drainage. Soil analysis revealed that available nitrogen was low (202.0 kg·ha-1) whereas available phosphorus (16.25 kg·ha-1) and potassium (236.0 kg·ha-1) were in the medium range. The present paper shows how to determine the economics of varying inm treatments. Cultivation of W. somnifera in India is gaining popularity among farmers;however, due to poor soil fertility, and costly chemical fertilizers and pesticides its production is not economical or profitable.

In wetland ecosystem, nitrogen along with other elements and its management is most imperative for the production of so many aquatic food, non-food and beneficial medicinal plants and for the improvement of soil and water characteristics. With great significant importance of inm (integrated nutrient management) as sources, emphasizing on management on nitrogen as a key element and its divergence, a case study was undertaken on such aquatic food crops (starch and protein-rich, most popular and remunerative) in the farmers' field of low-lying 'Tal' situation of New Alluvial Zone of Indian subtropics. The study was designed in factorial randomized block design, where, three important aquatic food crops (water chestnut (Trapa bispinosa Roxb.), makhana (Euryale ferox Salisb.) and water lily (Nymphaea spp.) as major factor and eleven combinations of organic and inorganic sources of nutrients as sub-factor was considered in the experiment. It revealed from the results that the production of fresh kernels or nuts of water chestnut (8.571 ha-1), matured nut yield of makhana (3.06 t ha-1) and flower stalks of water-lily as vegetables (6.38 t ha-1) including its nutritional quality (starch, protein, sugar and minerals) was remarkably influenced with the application of both organic (neem oilcake @ 0.2 t ha-1) and inorganic sources (NPK @ 30:20:20 kg ha-1 along with spraying of NPK @ 0.5% each over crop canopy at 20 days interval after transplanting) than the other inm combinations applied to the crops. Among the crops, highest WCYE (water chestnut yield equivalence) exhibited in makhana due to its high price of popped-form in the country, which is being exported to other countries at now. Sole application of both (organic and inorganic sources) with lower range did not produce any significant outcome from the study and exhibited lower value for all the crops. Besides production of food crops, inm also greatly influenced the soil and water characterization and it was favourably

机场飞机噪声污染控制方法的研究是民航研究领域中的一个重要实际问题,提高飞机和航空发动机的设计水平、搬迁机场飞机噪声污染对象,合理规划新建机场土地是机场飞机噪声控制方法研究中的三个重要研究方向。而通过对飞机最大起飞重量与测量点上噪声级数据的分析,充分表明飞机的最大起飞重量与测量点上噪声级之间存在高度的线性相关性,为了实现通过准确地控制飞机最大起飞重量而减小机场飞机噪声的污染这一方法,对机场所在平面飞机单机噪声等值线面积与测量点上噪声级总和之间的关系进行了研究。以飞机在起飞时为例,本文首先基于噪声声压级与传播距离之间关系的理论基础,建立了给定值飞机噪声等值线的面积与合格审定测量点上噪声级的总和二者之间的分析模型,从理论上说明了二者之间线性关系的合理性;其次利用综合噪声模型计算的42种所选机型的有效的数据,验证了二者之间高度线性相关的符合性,得到起飞、边线合格审定测量点上噪声级总和的改变量与给定值等值线面积变化百分比或给定值等值线面积改变量与起飞、边线合格审定测量点上噪声级总和改变量之间一一对应关系;最后以机型B737-700、B777-ER、A320-231、A318-111最大起飞重量和噪声级的数据,研究了飞机最大起飞重量与起飞、边线合格审定测量点上总和之间的关系,同时基于最大起飞重量与噪声级总和二者之间的关系,说明本文所研究的给定值等值线面积与起飞、边线合格审定测量点上噪声级总和二者之间关系在机场噪声污染控制中的应用,从而为机场周围社区飞机噪声污染定量化控制开辟了新的方法。

养分贮备和累积量(正流量戏去负流量)是可持续性的定量化指标,在本文中用于对农业生态系统进行分类。早期的研究结果表明,由于养分低贮备和负累积,非洲撒哈拉沙漠以南地区(SSA)的大部分农业生态系统都可被划入不可持续之列。为在非洲撒哈拉沙漠以南地区提高农业产量,并建立可持续农业生态系统,应采用"综合养分管理"(inm)技术体系,从而减少养分流失,并向系统中补充新的养分供给。综合养分管理技术的应用程度取决于国家和农场这两个层次上各种社会经济因素的相互作用。文中综述了目前我们在综合养分管理技术的研究应用方面所掌握的知识及存在的不足,并针对这些不足提出了一项综合养分管理研究议程。
