 How to protect land 如何保护土地
     Soil is a finite resource that cannot be substituted on a large scale as a basis for food production and many other essential ecosystem services such as nutrient recycling, water purification, habitat of organisms and many more. Nonetheless, fertile soil continues to be degraded and polluted directly or indirectly through open-cast mining, deforestation, overgrazing of pasture land, over-intensive agriculture, conversion of farmland into infrastructural and building areas, waste disposal, inputs of detrimental substances released through traffic, households and industrial activities into the atmosphere and other human activities.
     Protecting the quality of our soils is as important as protecting the air we breathe and the water we drink. Protecting soil is critical to protecting our ecosystems and our ability to raise crops or maintain a backyard garden.
     Soil quality can be a measure of soil productivity. Soil quality can also be linked to water quality.
     Specifically, soil quality is the capacity of soil to function within ecosystem boundaries to sustain biological productivity, maintain environmental quality, and promote plant and animal health. Soil quality focuses not just on characteristics such as nutrient availability and total organic matter levels, but also focuses on overall soil biological activity, organic matter content, water infiltration, and soil structure.
     Protecting and enhancing soil quality is accomplished through the use of soil conservation efforts; Best Management Practices for fertilizers and pesticides; and the proper use, handling and storage of agricultural chemicals, fertilizers, manures and soil amendments.
     With the human population still growing, urbanization increasing and climate conditions changing, the protection of this essential resource is not only more urgent than ever, but is also facing completely new challenges in the future.
     In response to these challenges, the mission of the Soil Protection group is to establish scientific knowledge required to sustain and manage the quality of soil as an essential basis for human and other life. This includes:
     ·early detection and identification of developments threatening ecological soil functions
     ·assessment of physical, chemical and biological stresses on soil and their impacts on soil quality and functioning
     ·characterization of risks for man and environment deriving from soil pollution and degradation
     ·development and evaluation of counter-measures against such threats and adverse impacts and of ways for a sustainable use of soil functions
     土地(Land)指地球表层(epigeosphere)的陆地部分及其以上、以下一定幅度空间范围内的全部环境要素(environmental elements),以及人类社会生产生活活动作用于空间的某些结果所组成的自然--经济综合体。
     狭义的土地,仅指陆地部分,这种观点较有代表性的是土地规划(land-use program)专家和自然地理学家的观点。广义的土地,不仅包括陆地部分,而且还包括光、热、空气、海洋......。
     减少土地侵蚀(erosion)的方法一般来说有以下几种:
     (1)消除或控制工业"三废"(three industrial wast)的排放。
     (2)加强土地污灌区(sewage irrigation region)的检测和管理。
     (3)合理施用化肥(chemical fertilizer)和农药(pesticide)。
     (4)增加土壤容量和提高土壤净化(soil sanitation)能力。







     New land use and conservation policies began to develop to meet this challenge.
     为了应付这一挑战,提出了使用和保护土地的新政策。
     Windbreaks not only protect land and crops from the wind. They can also provide wood products.
     防护林不仅能保护土地和庄稼免受狂风的侵蚀,还能提供木材制品。

     Conservationists had to carry on a constant struggle against lumber companies, ranchers, and homesteader.
     而资源保护学家们不得不和木材公司、牧场主以及分得土地的移民进行不断的斗争。
     The result indicates that in the future the land use in Yangzhou City will take on characteristics as follows: the area of cultivated land will reduce continually, the scale of construction land in the city proper and towns will still be increasing, and the unused land will be decreasing rapidly.
     预测结果表明:扬州市未来的土地利用主要存在耕地面积将持续减少、城镇建设用地规模仍将继续增大、未利用地面积减少较快等特征。
     In mapping out the general plans for land use, the provinces, autonomous regions and municipalities shall ensure than the total amount of cultivated land under their jurisdiction shall not be reduced.
     省、自治区、直辖市人民政府编制的土地利用总体规划,应当确保本行政区域内耕地总量不减少。
     For example, a reduction in organic carbon and nutrients, including phosphorus or nitrogen, as may occur in intensively farmed areas, de creases the fertility of soils.
     例如,过度耕种的土地可能发生有机碳和营养的减少,包括磷或氮,降低了土壤的肥力,在农作物密集的地区往往是这样。
     The methods involve soil fertility management as well as reduced tillage.
     方法包括实行土地施肥管理和减少耕地。
     To cherish and give a rational use to the land as well as to give a true protection to the cultivated land are seen as a basic principle of land use in the country.
