| Terms for subject Environment (7397 entries) |
| genetic pool (The total number of genes or the amount of genetic information possessed by all the reproductive members of a population of sexually reproducing organisms) | 基因库 | |
| genetic resource (The gene pool in natural and cultivated stocks of organisms that are available for human exploitation. It is desirable to maintain as diverse a range of organisms as possible, particularly of domesticated cultivars and their ancestors, in order to maintain a wide genetic base. The wider the genetic base, the greater the capacity for adaptation to particular environmental conditions) | 遗传资源 | |
| genetic variation (Change in one or more phenotypic characteristics, due to gene mutation or rearrangement, environmental effects, etc.) | 遗传变异 | |
| genetically modified organism (An organism that has undergone external processes by which its basic set of genes has been altered) | 基因改造生物 | |
| genetics (The science that is concerned with the study of biological inheritance) | 遗传学 | |
| genotoxicity | 基因毒性 | |
| geo-referenced data | 地理参考数据 | |
| geo-referenced information (Data delimiting a given object, either physical or conceptual, in terms of its spatial relationship to the land, usually consisting of points, lines, areas or volumes defined in terms of some coordinate system) | 地理参考信息 | |
| geodesy (A subdivision of geophysics which includes determination of the size and shape of the earth, the earth's gravitational field, and the location of points fixed to the earth's crust in an earth-referred coordinate system) | 大地测量 | |
| geogenic factor (Geogenic factors are those which originate in the soil, as opposed to those of anthropic origin (anthropogenic)) | 环境地球化学因素 | |
| geographic cirque (A deep steep-walled half-bowl-like recess or hollow, variously described as horseshoe- or crescent-shaped or semi-circular in plan, situated high on the side of a mountain and commonly at the head of a glacial valley and produced by the erosive activity of a mountain glacier. It often contains a small round lake, and it may or may not be occupied by ice or snow) | 高山冰积洼地 | |
| geographic information system (An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information that can be drawn from different sources, both statistical and mapped) | 地理信息系统 | |
| geographical distribution of population (The number of inhabitants in or spread across designated subdivisions of an area, region, city or country) | 人口地理分布 | |
| geographical projection (A representation of the globe constructed on a plane with lines representative of and corresponding to the meridians and parallels of the curved surface of the earth) | 地理投影 | |
| geography (The study of the natural features of the earth's surface, comprising topography, climate, soil, vegetation, etc. and man's response to them) | 地理学 | |
| geological disaster (Disasters caused by movements and deformation of the earth's crust) | 地质灾害 | |
| geological process (Dynamic actions or events that occur at the Earth's surface due to application of natural forces resulting from gravity, temperature changes, freezing and thawing, chemical reactions, seismic shaking, and the agencies of wind and moving water, ice and snow. Where and when a force exceeds the strength of the earth material, the material is changed by deformation, translocation, or chemical reactions) | 地质过程 | |
| geology (The study or science of the earth, its history, and its life as recorded in the rocks; includes the study of geologic features of an area, such as the geometry of rock formations, weathering and erosion, and sedimentation) | 地质学 | |
| geometric correction (A remote sensing term referring to the adjustment of an image for geometric errors) | 几何校正 | |
| geomorphic process (The physical and chemical interactions between the Earth's surface and the natural forces acting upon it to produce landforms. The processes are determined by such natural environmental variables as geology, climate, vegetation and baselevel, to say nothing of human interference. The nature of the process and the rate at which it operates will be influenced by a change in any of these variables) | 地貌形成过程 |
