氮素管理的指标 总被引:36,自引:1,他引:35
用什么指标(indicators或indexes)来衡量不同尺度或生产体系氮素管理的优劣,是提高氮素管理水平的核心问题。近年来,国际上在氮素管理方面提出了许多新概念、方法和指标,以客观评价和改进氮素管理水平,为生产者和政策制定者提供评判标准。本文系统介绍了国际上氮素管理指标的概念、含义、计算方法及对结果的解析,包括:(1)氮素投入、收益与环境效应的关系;(2)氮素收支(budget)、氮素平衡(balance)和氮素盈余(surplus);(3)氮素利用率(Nitrogen Use Efficiency,NUE);(4)氮素利用率与氮素输入、输出及盈余的关系;(5)旱地作物收获后土体硝态氮允许残留量(Residual nitrate-N)。在此基础上,汇总了我国在不同尺度、不同土壤-作物体系氮素研究结果,初步建立了我国典型农田的氮素管理指标,为实现优良的氮素管理提供科学依据。 相似文献

开展地块后期管理是保障人居安全及彻底打赢土壤污染防治攻坚战的关键一环。针对污染地块调查与风险评估、修复与风险管控、效果评估各阶段存在的不确定性,以及修复后地块存在污染物浓度反弹和风险管控措施失效等可能风险,有必要开展污染地块修复和风险管控后期管理研究。为此,基于欧美国家污染地块管理经验,综合考虑我国污染地块环境管理要求,确定了需开展后期管理的地块类型,分析了后期管理过程中长期监测、运行维护、制度控制及回顾性评估4种措施的重要作用,初步构建了污染地块修复和风险管控后期管理框架体系,明确了长期监测对象与目的、监测点位、监测指标、监测频次与周期,运行维护内容,制度控制措施,回顾性评估要求及后期管理的终止条件。实施后期管理是贯彻落实《中华人民共和国土壤污染防治法》的重要体现,将为污染地块修复和风险管控后的安全再利用提供重要保障。 相似文献

Maintenance and improvement of soil quality across spatially variable soils in continuous cropping systems are critical to sustaining agricultural productivity and environmental quality. The objectives of this project were (i) to study the effects of variable-rate application of animal manure on selected topsoil quality parameters across site-specific management zones (MZs) and (ii) to evaluate the variable-rate applications of manure using risk-assessment tools of nitrogen (N) leaching and phosphorus (P) runoff indices to understand its impact on environmental quality. This study was conducted in northeastern Colorado on continuous and furrow-irrigated maize fields. Experimental strips, 4.5 m wide and 540 m long, spanned across all MZs with treatments nested within MZs in the field. Variable rates of dairy and beef feedlot manure applied on irrigated and dryland fields respectively ranged from 0 to 67 Mg ha?1. Surface soil quality parameters evaluated before and after this study included bulk density, organic matter, water-holding capacity, electrical conductivity, and particle-size analysis. Results indicate that animal manure applications of 44 and 67 Mg ha?1 significantly (P ≤ 0.05) increased soil organic matter and decreased bulk density of low- and medium-productivity-level MZs and had no significant impact on surface soil organic matter and bulk density of the high-productivity-level MZs. Animal manure significantly (P ≤ 0.05) increased surface soil water-holding capacity and soil electrical conductivity across zones; however, the maximum manure-induced soil EC was 1.0 dS m?1, which was below levels regarded as potentially harmful for maize production. Soil texture was not affected by animal manure applications. Colorado N leaching and P index indicated no environmental hazard associated with variable rate application of animal manure across MZs. This study indicates that variable-rate application of animal manure across MZs has potential to improve or maintain soil quality parameters over time without impairing the environment. 相似文献

The area of land which man manipulates through cultivation is 3.2×109 ha; however, the impact from this system has been large. The soil-plant-atmosphere complex is very dynamic with the plant continually growing throughout a constantly changing atmospheric environment, i.e., radiation, temperature, and precipitation. However, a basis for all exchanges is the energy balance and all changes are made through this balance. Two impacts of this system are realized in water and wind erosion. Both are detrimental to agricultural land and proper management of the system alleviates the impact of these two forces. Other changes which occur are reduction in evaporation and soil temperature under crop cover. There is needed, however, a more thorough understanding of the energy exchanges throughout the growing season, especially as it applies to feed-backs between plant response and the environment, soil derived aerosols, and biogenic ice nuclei. These will provide a better understanding of how we manipulate this complex for maintenance of our world's food supply. 相似文献

With the declaration of the State of Israel in 1948, Israel inherited the Ottoman law for water and not the English Rule of Riparian Rights. The Ottoman law allowed the State to control the water sources and, in fact, did not allow private ownership of water sources. In its early years, Israel promulgated some of the most forward looking legislation in the world concerning protection of water sources. But as time went on, Israel lost its preeminence in the water protection field, while other countries revised their water laws in light of the environmental revolution. It is now time for Israel to redesign its water system along catchment basin lines. 相似文献

在水源集水区中最常造成水质恶化与水量流失之因素主要是来自变更土地使用目的的开发行为。台北水源特定区系台湾第一个经由都市计划程序规划之水源、水质、水量保护区,其管制规范系以土地使用管制为主,故无论在法令配合、人力、经费编列及业务执行运作上均系首创,因此特为本文,藉由现行经营、管理、法令制度等之探讨,以祈有助于提供未来水源保育及永续利用政策制定之参考。 相似文献
