The original data were downloaded from theNational Bureau of statistics in People's Republic of China. The two data werethe situation and annual changes of water resources in China from 2010 to 2016.
1. The Total water resources (2010-1016)
2. The amount of surface water resources (2010-1016)
3. The amount of groundwater resources (2010-1016)
4. Repetition of surface water and groundwater resources (2010-1016)
5. Per capita water resources (2010-1016)
According to the definition of water resources in the INTERNATIONAL GLOSSARY OF HYDROLOGY of the World Meteorological Organization and UNESCO, water resources refer to water sources that are available or may be utilized, which should have sufficient quantity and suitable quality and meet the need for specific use of a certain place for a period of time. Please. According to the definition of water resources in water conservancy science and technology nouns published by the national scientific and technological noun Review Committee, water resources refer to the water that has a certain amount and available quality on the earth which can be supplemented and utilized from the natural world.
72% of the earth's surface is covered by water, but fresh water resources account for only 0.5% of all water resources. Nearly 70% of the fresh water is fixed in the ice layer of Antarctic and Greenland, and the rest is soil moisture or deep groundwater, which can not be used by humans. Only less than 1% of the earth's fresh water or about 0.007% of the water can be used directly for human beings, and the per capita freshwater resources in China account for only 1/4 of the world's per capita freshwater resources.
China has a vast territory, but because of its large population, the number of water resources per capita is relatively small. China has a large population. It is the largest population in the world. Although China is also a big country of water resources, the per capita freshwater resources only account for 1/4 of the world's per capita fresh water resources. The main idea of making the visualization of this set of data is to let everyone know about the current situation of water resources in China, and at the same time appeals to everyone to cherish water resources.
It is important for everyone to cherish water resources, which is of great significance for a country and even for the world. Besides water resources, we should also economize on all kinds of other resources. A sustainable development of the earth requires us to cherish resources and work together.
Question:
1. visualization is full of advantages. Isthere any drawback in visualization?
Now we are seeking to turn data into visualform, which is clear and easy to read after visualization. But is there ashortcoming of visual products? Is there a gap in reading? Is there anyobstacle to people with lower educational level?
2. I want to say something about my data.
Data is rigid, but the resource problemhidden behind data and human survival is a serious problem. We need to see theunderlying meaning through data and visual products.
3. The obstacles I encountered during thevisualization process.
Visualization is originally a job requiringtechnology, and I lack a strong technical level. We still need to learn andthink more.
