课程名称：从零开始学习土壤科学 课程概述：本课程探讨土壤作为地球表面自然资源的研究，包括土壤的形成、分类与制图，以及土壤的物理、化学、生物和肥力特性，以及这些特性如何与土壤的使用和管理相关。土壤科学涵盖多个子领域，如土壤成土学（研究土壤的形成、化学、形态和分类）和土壤生态学（研究土壤与生物，特别是植物的相互作用），这些名称有时可以互换使用。土壤科学的进步和对土壤的进一步理解，得益于工程师、农艺师、化学家、地质学家、自然地理学家、生态学家、生物学家、微生物学家、森林学家、公共卫生专家、考古学家以及区域规划专业人士等多种专业人士的共同努力。 土壤科学家对如何在全球人口增长、潜在水危机、日益增加的食品需求和土地退化的背景下保护土壤和可耕种土地表示关切。根据1914年的百科全书定义，土壤是一种“在岩石表面上由岩石的风化或崩解生成的各种土壤类型”，这表明19世纪以来对土壤的历史理解。19世纪末，杜库恰耶夫的土壤观念演变为20世纪对土壤的理解——土壤作为一种被生物活动改变的物质。由此产生的观念是，缺乏生物的土壤仅是地球表面的一部分。随着我们不断加深对土壤中能量传输和转化的理解，土壤的概念也在不断发展。
The study of soil as a natural resource on the surface of the earth includes its creation, categorization, and mapping, as well as its physical, chemical, biological, and fertility features and how these properties relate to its use and management.Sometimes names that pertain to specific subfields of soil science, including pedology (the formation, chemistry, morphology, and categorization of soil) and edaphology (the interaction of soils with living organisms, particularly plants), are used interchangeably with soil science. The many associations involved are what account for the variety of names connected with this profession. Indeed, a wide range of professionals, including engineers, agronomists, chemists, geologists, physical geographers, ecologists, biologists, microbiologists, silviculturists, sanitarians, archaeologists, and regional planning experts, contribute to the advancement of the soil sciences and the further understanding of soils. Concerns regarding how to protect soil and arable land in a world with a growing population, a potential water crisis, rising per capita food demand, and land degradation have been expressed by soil scientists. "The many kinds of earth on the surface of the rocks, generated by the breaking down or weathering of rocks," according to an encyclopaedia definition from 1914. helps to demonstrate the historical perspective on soil that has been held since the 19th century. Dokuchaev's notion of soil from the late 19th century evolved into one of soil as an earthy substance that has been modified by living activities in the 20th century. The consequent idea is that soil devoid of live organisms is only a component of the surface of the planet.The idea of soil is being further developed in light of our growing understanding of how energy is transported and transformed within soil.
