中国1∶100万景观生态制图设计

中国1∶100万景观生态图系借鉴国内外传统景观制图方法和制图规范,在遥感、地理信息系统先进技术的支持下,设计研制其制图方法、制图内容、样图和技术流程,同时提出初步的景观分类系统,为今后编制中国1∶100万景观生态图奠定基础。

Designing and Mapping of 1:1 000 000 Landscape Ecologic Maps of China

Based on advanced techniques such as Remote Sensing, Geographical Information System and Computer-aided cartography etc., this paper presents the significance and actual progress in landscape ecologic mapping at home and abroad, discusses traditional mapping methods and mapping criterion on thematic maps, design on modern computer automatic mapping method, map contents and mapping procedure of landscape ecologic maps. The mapping contents includes: (1) probing into or researching new mapping method and mapping criterion based on RS and GIS; (2) researching classification indexes and classification system; (3) researching and designing modern computer automatic mapping method and technology; and (4) finishing and publishing the 1∶1000 000 landscape ecologic maps of China, and mapping manuals etc. The research steps include research historical analysis of the study area, basic database construction, analysis of regional landscape characteristics, landscape classification and mapping, and finial integrated mapping. The maps of landscape ecology include 8 formats, the first one is color terrain map based on 1∶250 000 DEM and mapping explanation, the second-third one is ETM imageries in 2000, including typical field photographs and geologic profiles, the fourth-fifth one is characteristics analysis of several key areas, the sixth-seventh one is the main type map of landscape ecology, including classification system and legend system, and the last one is function division map of key areas. Based on traditional classification systems of vegetation, LUCC and FAO, the thesis integrates two important indexes of relief and land cover, and presents new landscape classification system.The study breaks traditional thematic mapping method of single elements, which can provide method of presupposition for finishing the 1∶1 000 000 landscape ecologic maps of China in future and integrate scientific research with productive practice. It can not only update actual basic materials based on RS data, present actual status of the study area, but also discuss ecological environmental problems, present reconstructing methodology or measures. So, the study has theoretical importance and practical application value.
