Land
Land is a delineable [diˈlinieit] area of the earth's terrestrial [tiˈrestriəl] surface, encompassing all attributes of the biosphere immediately above or below this surface including those of the near-surface climate the soil and terrain forms, the surface hydrology (including shallow lakes, rivers, marshes, and swamps [swɔmp]), the near-surface sedimentary /ˌsedɪˈmentəri/ (沉淀性的) layers and associated groundwater reserve, the plant and animal populations, the human settlement pattern and physical results of past and present human activity (terracing, water storage or drainage structures, roads, buildings, etc. [etˈsetərə] (=et cetera)). (UN, 1994)
Land use
Land use is the human modification of natural environment or wilderness into built environment such as fields, pastures, and settlements. The major effect of land use on land cover since 1750 has been deforestation of temperate regions. More recent significant effects of land use include urban sprawl, soil erosion, soil degradation, salinization [səlini'ze
iʃən], and desertification. Land-use change, together with use of fossil fuels, are the major anthropogenic sources of carbon dioxide, a dominant greenhouse gas. It has also been defined as "the total of arrangements, activities, and inputs that people undertake in a certain land cover type".

Land cover
Land cover corresponds to a (bio) physical description of the earth's surface. It is that which overlays or currently covers the ground. This description enables various biophysical categories to be distinguished - basically, areas of vegetation (trees, bushes, fields and lawn), bare soil, hard surfaces (rocks, buildings) and wet areas and bodies of water (watercourses水流(河床), wetlands). There are two primary methods for capturing information on land cover: field survey and thorough analysis of remotely sensed imagery. The nature of land cover is discussed in Comber et al. (2005).

Difference
Land use corresponds to the socio-economic description (functional dimension) of areas: areas used for residential, industrial or commercial purposes, for farming or forestry, for recreational or conservation purposes, etc. Links with land cover are possible; it may be possible to infer land use from land cover and conversely. But situations are often complicated and the link is not so evident. Contrary to land cover, land use is difficult to 'observe'. For example, it is often difficult to decide if grasslands are used or not for agricultural purposes. Distinctions between land use and land cover and their definition have impacts on the development of classification systems, data collection and information systems in general. (UNEP)
Land cover is distinct from land use despite the two terms often being used interchangeably. Land use is a description of how people utilize the land and socio-econo
mic activity - urban and agricultural land uses are two of the most commonly recognised high-level classes of use. At any one point or place, there may be multiple and alternate land uses, the specification of which may have a political dimension.
securingLand management
Land management can be defined as the process of managing the use and development (in both urban and suburban settings) of land resources in a sustainable way. Land resources are used for a variety of purposes which interact and may compete with one another; therefore, it is desirable to plan and manage all uses in an integrated manner.
Land administration
The concepts of land administration are the reflection of views on land properties. In China, scholars hold ideas that land administration is the process of organization, coordination, supervision and management on land resources, land use, land property rights and land profit with political instruments for sake of whole society.
Other studies on land administration, cadastral [kə'dæstrəl] titles and land market, urban land administration, and land sustainable conservation, altogether make these factors-land resources management, land assets supervision and land political governance for sustainability constitute foundation of land administration.
Difference
There are many factors according to which administration can be distinguished from management. From the nature of work, administration is concerned about the determination of objectives and major policies of an organization; management puts into action the policies and plans laid down by the administration. From the nature of status, administration consists of owners who invest capital in and receive profits from an enterprise; management is a group of managerial personnel who use their specialized knowledge to fulfill the objectives of an enterprise. From Main functions, administration involves in planning and organizing functions; management involves in motivating and controlling functions.
Land use planning
Land use planning is the term used for a branch of public policy which encompasses [inˈkʌmpəs] various disciplines which seek to order and regulate the use of land in an efficient and ethical /ˈeθɪkəl/ way. Despite confusing nomenclature nəuˈmenklətʃə,术语,命名系统, the essential function of land use planning remains the same whatever term is applied. The Canadian Institute of Planners offers a definition that: "Land use planning means the scientific, aesthetic [i:sˈθetik], and orderly disposition of land, resources, facilities and services with a view to securing the physical, economic and social efficiency, health and well-being of urban and rural communities"
From Wikipedia, the free encyclopedia
There is bound to be conflict over land use. The demands for arable land, grazing, forestry, wildlife, tourism and urban development are greater than the land resources available. In the developing countries, these demands become more pressing every year. The population dependent on the land for food, fuel and employment will double within th
e next 25 to 50 years. Even where land is still plentiful, many people may have inadequate access to land or to the benefits from its use. In the face of scarcity, the degradation of farmland, forest or water resources may be clear for all to see but individual land users lack the incentive or resources to stop it.
