Abstract

The utility model discloses a simulative topographic map of China, which is characterized in that the whole base of the map (the level of the sea) is an arc-shaped curved surface with four sides inwardly bow-shaped and fixed on the frame. Being easy and simple to produce and process with a low cost, the utility model is helpful for high school and primary school students to get a better knowledge of the topography and topography of China and to perform better in the study of geography, and at the same time brings convenience for researches and studies on earth science and environmental science.

Description

China artificially generated terrain figure

Technical field

The utility model belongs to the map of geoscience, Research of Environmental Sciences, teaching demonstration.

Background technology

As everyone knows, the earth is a spheroid.People have made multiple signal instruments such as terrestrial globe, map in order to be familiar with, to study the earth better." the Chinese topomap " that published and distributed by the establishment of map Science Institute, China Map Press reflected Chinese terrain feature especially very intuitively, yet blemish in an otherwise perfect thing is, China is vast in territory, the most eastern border is in the main channel intersection in the Heilungkiang and the Wusuli River of Heilongjiang Province, the most western border is on the Pamir Mountain Area of Xinjiang Uygur Autonomous Regions, easting is striden longitude 62 degree from 5200 kilometers; The most northern border is on Heilungkiang, the center line of Heilungkiang main channel to the north of the Mo River, and the most southern border is near the Zengmu Reef on the Nansha Islands, Guangdong Province, and north and south is extended 5500 kilometers, strides about 50 degree of latitude.On this area of 9,600,000 square kilometres, no matter be from the east to the west, still from south to north, span is very big, thereby " the Chinese topomap " worked out on the plane is regarded as in the sea level significant limitation is just arranged, and has lost the build-in attribute of topography and geomorphology.

Summary of the invention

The purpose of this utility model aims to provide a kind of Chinese artificially generated terrain figure, and it organically combines the feature of globe surface topography and geomorphology and the making advantage of plane map, forms a kind of be rich in cube sense, image, Chinese artificially generated terrain figure intuitively.

The purpose of this utility model can realize by following measure:

A kind of Chinese artificially generated terrain figure, whole map base portion (sea level) is curved surface and upwards arches upward, and curved surface four limits are arc, arc inside low dip and be consolidated in frame.

The beneficial effect of advantage of the present utility model and generation is:

1, the Chinese artificially generated terrain figure that sphere is made into being regarded as in the sea level can more directly perceived, scientifically show Chinese topography and geomorphology, helps deepening the understanding of students in middle and primary schools to Chinese topography and geomorphology, helps the study of students in middle and primary schools to geographical course.Simultaneously, bring convenience also can for the research work of being engaged in geoscience and environmental science;

2, make simply, handling ease, with low cost.

Embodiment

China artificially generated terrain figure amplifies the Chinese landform part of landform globe surface in the earth surface ratio, whole map base portion 1 (sea level) is curved surface and upwards arches upward, and curved surface four limits are arc, arc inside low dip and be consolidated in frame 2.

China artificially generated terrain figure also can be an area.

China artificially generated terrain figure specification can be opening of issuing on the market, two and opens, four model such as opens.

Claims

1, a kind of Chinese artificially generated terrain figure is characterized in that whole map base portion (1) is curved surface and upwards arches upward, and curved surface four limits are arc, arc inside low dip and be consolidated in frame (2).
