人口密度空间分布数字模拟中国Spatial distribution of population density is simulated on the ba sis of fusing remotely sensed data, meteorological data, soil data and statistical data by means of a grid-generation based model that is newly constructed in this paper. The result shows that the highest...
China carried out its fifth national population census on November 1, 2000. It has a population of 1,295.33 million.
As you can see, these maps of China tell an interesting story, not just from a micro level (within the country) but also on a more macro level (in contrast to the rest of the world). China’s population has boomed over the past century, but what makes it so interesting is how the...
The value for Population density (people per sq. km of land area) in China was 149.71 as of 2020. As the graph below shows, over the past 59 years this indicator reached a maximum value of 149.71 in 2020 and a minimum value of 70.06 in 1961....

However, detailed assessment of the population distribution data of countries that have large populations (such as China) and significant variation in distribution requires improved data processing methods and spatialization models. This paper described the construction of a novel population spatialization ...

Although food has been proposed as a possible factor on population regulation of small mammals, evidence of food restriction in field conditions is still lacking. Food restriction is generally thought to occur in high-density years of oscillating populations of small mammals. By using two body condi...

Population density is calculated as population divided by total land area. The European city-state of Monaco is the most densely populated country with a population density of 25,927 people per sq. km (67,150/sq mile), and its population only numbers in thousands. The Chinese territory of ...
