TEXT OF THE ABSTRACT (NO MORE THAN 400
WORDS).
1. Overall design for “The Electrical Atlas of Regional
Development in China” (“E-atlas” for short)
The contents and expressions of “E-atlas” are
determined in terms of the study of regional development. The visual expression
of regional development phenomena: Use positioning point symbols and
statistical tables and graphs to express the elements of regional development. Using
points, lines and polygons expresses the structural adjustments and
developmental patterns. The correlations among objects were described based on
the inside and organic connection among population, economy, city, resource,
environment and regional development from different aspects. According to the
results of analysis and synthesis, the situation of present and future, the
different levels of description and evaluation，the atlas
contains analytical maps of single element or multi-element which can be used
to evaluate and forecast developments. The atlas has multilevel dimensions.
2. Design for topic of “E-atlas”
There
are lots of issues about resource, environment, society and economy caused by
regional development. “E-atlas” integrally describes these issues on aspects of
history, present and the future. “E-atlas” reflects features of
regional development in
3. The framework of “E-atlas”
The framework of
“E-atlas” not only reflects the whole character of map region but also reflects
regional peculiarity.
“E-atlas” is
built on the study of economic development, social development, natural
resources and ecological environment. There are several sub-topics under each
topic, and each sub-topic was displayed by several maps. With this structure, “E-atlas”
is systematic.
“E-atlas” mainly
composed of four modules of electrical mapmaking system, map management system,
map browse system and regional development database querying system.
4. The structure of “E-atlas”
According to the rule
of regional developmental, the content of “E-atlas” contains four parts:
economic development, social development, natural resources and ecological environment.
The “E-atlas” consists of 11 map groups: map groups of preface, economy, external trade, industrial development, agricultural development,
infrastructure, population, urban construction, people's lives, resource and
environment and sustainable development.
5. The function of “E-atlas”
“E-atlas” can be read
in computers directly and display maps on the screen. User can inquire
catalogue, display maps, zoom in or out, browse map, inquire interested
property, search by expression, analyze the model of regional development and
read supplementary explanation via person-computer interaction. The function of
spatial analysis: The analysis of regional
economic developmental based on statistic data could
be made, and the result for space-time variety rule could be expressed in electrical
map.
