  1. Field observations and physical models may be used to investigate pollutant transportation and dispersion within urban canyons and validate numerical models. on the other hand, validated numerical models are often applied to simulate in detail atmospheric dispersion within the urban canopy. the numerical results in combination with physical model and or field data may be used to assess urban air quality and support decisionmaking for pollution control strategies and traffic planning

    外場觀測和物理模擬可以考察街谷內污染物的傳輸擴散規律並對數值模式進行檢驗,另外,復雜的數值模式則可對城市冠層內大氣擴散問題進行詳細模擬,數值模擬和外場觀測及物理模擬相配合,可用於環境質量評價污染控制決策及交通規劃。

  3. Agricultural intensification plays an important role in stabilizing the food production in china, while bringing about an increasing negative impact on the soil and eco - environment as a result of the long - term highly - intensive land use and agricultural chemical overuse, thus leading to degradation of soil physical, chemical and biological properties, which are demonstrated as soil nutrient imbalance, soil acidification, pollutant accumulation, and biodiversity deterioration and posing serious stress and threat to the ecosystem per se and the environment

    摘要集約化農業對保障我國糧食安全發揮了巨大的作用,但其長期的土地高強度利用和農用化學品過量投入的負面影響也日益顯現,導致的以土壤養分失衡、土壤酸化、有害物質積累、生物多樣性衰退等為主要表現形式的土壤物理、化學和生物學退化,給生態系統本身與環境都帶來了巨大壓力和嚴重威脅。
  4. There are three methods which have potential of development for controlling mercury, namely the common physical coal cleaning technology, existing pollutant control facilities, and injecting sorbent, such as activated carbon etc., into the flue gas

    有發展潛力的汞控制方法有3種:常規物理洗選煤技術、現有污染物控制裝置和煙氣中噴入活性炭等吸附劑方式。
  5. The paper, by using the technology of gis and the method of systems engineering, analyzed the development situation of regional society and economy, the natural physical conditions, the situation of pollutant, and density distributing characteristics of pollutant, then set up the echoing relationship between pollute source diffusion and quality of air environment, which could make controlling index of pollution source discharging be closely linked with the quality of environment

    本研究採用gis技術,利用系統工程的方法根據區域社會經濟發展狀況、自然地理條件、污染源狀況及污染物濃度分佈特徵進行綜合分析研究,研究建立了污染源擴散與大氣環境質量的響應關系,將污染源排放控制指標與區域的環境質量直接掛鉤。
