福建省生态环境综合系列图编制 总被引:1,自引:0,他引:1
福建省生态环境综合系列图是数字福建应用项目《福建省生态环境动态监测与管理系统》中数据库建设的一个重要基础工作,包括生态环境类型图、生态环境评价图、生态功能区划图以及地势图、地貌图、土壤图、植被图、土地利用图等。编制工作是在参考各种图件和文字等资料基础上,以遥感(LandSatETM)为主要信息源,根据影像特征的差异勾绘生态环境单元并记录各单元一系列相关信息,根据单元图属性派生其它图(地势图除外)。编制过程中着重解决了各专题图的分类系统和编码系统、多源信息复合、遥感综合系列制图与地图演绎法结合应用、3S技术的综合应用、多种制图技术的综合应用等问题。 相似文献

目前我省各县、市的各种名目繁多的城市交通图、旅游图、工商企业图、地图册一版再版.究其内容则大同小异,一些并不具备编制地图资格的单位,在利欲的驱动下打着各种旗号纷纷登场加入编制地图的行列。他们一无资料,二无技术力量,照着别人早已出版的地图东拼西凑,有的甚至原封不动照搬, 相似文献

The principles of systems mapping are employed in a model simulating the effects of human activity on the environment. The model takes the form of series of maps which are organized within three basic units or “blocks.” Block I contains general preliminary maps of land use and environmental change within an area which can serve as a basis for subsequent forecasting and proposals for improving land use. Block II contains maps that take stock of, evaluate, and predict human impacts on specific environmental components, and show the spatial distribution of measures proposed to ameliorate these impacts. Block III consists of maps synthesizing the component-related information of the preceding block for the purpose of providing summary assessments about the condition of the environment and land use conflicts in an area and targeting areas deserving the most comprehensive reclamation efforts. Methods of compiling the various maps are described in detail. Translated from: Izvestiya AN SSSR, seriya geograficheskaya, 1986, No. 2, pp. 114–127. 相似文献

System corrected multispectral imagery of the Central Afar region in Ethiopia provided by the ERTS-1 satellite was evaluated for the purposes of natural resource inventory under the headings of geology, vegetation, soils and land use. The methods and results of image interpretation are discussed in detail and the following general conclusions may be drawn. The ERTS-1 imagery provides a synoptic view of the region that is very nearly orthographic. A colour composite print of multispectral bands 4, 5 and 7 is superior to any of the individual black and white bands for natural resource interpretation. Exploratory soil, vegetation and land use maps and reconnaissance geological maps can be constructed rapidly. The small percentage of forest and agricultural land in this particular area enhances the geological value of the image. Satellite imagery is a valuable addition to the more conventional forms of aerial photography for agricultural studies provided that the study area covers at least 10 000 km2. Ground control was acquired between October 1972 and May 1973. 相似文献

Procedures for the compilation of new maps showing the quantity and intensity of precipitation, which take into account its frequency, are outlined. The maps were prepared for the atlas The Natural Environment and Natural Resources of the World. A comparison is made with earlier published maps compiled by other methods. Translated by Jay K.

A review of basic theoretical principles of “ecological” mapping and types of maps of the environment sets the stage for a more detailed treatment of ecological-geographic maps—maps portraying a wide range of nature-society and nature-nature relationships—as they are used in support of economic development and environmental monitoring in Siberia. Particular attention is devoted to the compilation of map series, which include ecological-geographical maps, for the Lake Baykal area, BAM service zone, West Siberia, and specific territorial production complexes (e.g., Kansk-Achinsk TPC).

A method for the compilation of 1:3,000,000-scale maps of natural nival-glacial phenomena is proposed for an area of the High Pamir Range in Soviet Central Asia. Such maps depict the distribution, frequency and intensity/magnitude, and potential impacts of such natural hazards as avalanches, mudslides, “dirty snow” avalanches (combined avalanches-mudslides in late spring), icings (naledy), and glacier pulsations, and are used in the planning of construction and the maintenance of roads and other transportation corridors during winter and spring. Hypothetical examples of the use of the maps are provided. Translated from: Materialy glyatsiologicheskikh issledovanly, USSR Geophysical Committee Publication No. 55.
