全球土地与农资数据
收藏资源简介：
土地数据是反映土地利用系统及土地利用要素的状态、特征、动态变化、分布特点，以及人类对土地的开发利用、治理改造、管理保护和土地利用规划等数据资料。农用物资简称农资，一般是指在农业生产过程中用以改变和影响劳动对象的物质资料和物质条件，如农业运输机械、生产及加工机械、农药、种子、化肥、农膜等等。土地不是农用物资，而是农业劳动对象（农业生产过程中人们将劳动加于其上的物质对象），与农用物资相比，它具有数量有限，位置固定，功能不可代替，肥力可以再生等特点 。 CnOpenData全球土地与农资数据收录了全世界200多个国家的土地和农用物资信息，分为土地利用、土地覆盖、按养分分类的肥料、按产品分类的肥料、按产品分类的肥料 （化肥）、牲畜粪便、杀虫剂自用、杀虫剂贸易、农田营养预算、牲畜、生物能源、地面温度变化等12张表，涵盖领域、地区、要素、科目、年份、单位、值、标识、说明等字段。
Land data refers to datasets and information that reflect the status, characteristics, dynamic changes, and distribution patterns of land use systems and land use elements, as well as human activities such as the development and utilization, governance and transformation, management and protection, and land use planning related to land. Agricultural supplies, abbreviated as "agri-supplies", generally refer to material resources and conditions used to alter and affect the objects of labor during agricultural production, such as agricultural transportation machinery, production and processing machinery, pesticides, seeds, fertilizers, agricultural plastic films, and the like. Land is not an agricultural supply, but rather the object of agricultural labor — the material entity onto which human labor is applied during agricultural production. Compared with agricultural supplies, land features limited quantity, fixed location, irreplaceable functions, and renewable soil fertility. The CnOpenData Global Land and Agricultural Supplies Dataset compiles land and agricultural supplies information for over 200 countries globally. It is organized into 12 tables: land use, land cover, nutrient-classified fertilizers, product-classified fertilizers, product-classified fertilizers (chemical fertilizers), livestock manure, pesticide self-use, pesticide trade, farmland nutrient budget, livestock, bioenergy, and ground surface temperature change. The dataset includes fields such as domain, region, factor, subject, year, unit, value, identifier, and description.
