Based On GIS The Research Of Population District Model In China Continent

According to the national region economy division standard, this article divides the nation into eight wide zones: the northeast synthesizes economic zone, the north coast synthesizes economic zone, the eastern coast synthesizes economic zone, the south coast synthesizes economic zone, the middle reaches of Yellow River synthesizes economic zone, the Middle reaches of Yangtze River synthesizes economic zone, the big southwest synthesizes economic zone and the big northwest comprehensive economic zone. In various regions, analysis the ration relations of the population spatial distribution characteristic and correlation factors,via the theoretic, method and technique, separately gained the key factors which have close correlation with population, establishes the population mathematical model, finally carries on the precision confirmation in various regions population model, and analysis the characteristic of the population distribution and the factors which affect various regions population distribution. The confirmation method include independent-samples T test and the correlation analyse of model-population and census population. The conclusion of this paper is below:1. The northeast synthesizes economic zoneKey factors: GDP, jw and area of residential;Population model: y = 0.165x₁ +5×10^-7x₂^3.2608+17.495x₃^0.4796+170406.49 ( x₁ is GDP, x₂ is jw, x₃ is area of residential)The result of T test: the value of sig is 0.362 which is bigger than 0.05, the value of F is 0.846, and the value of R² is 0.8427;The characteristic of population distribution: the distribution of population is denseness in the plain zone where the accumulate temperature is higher and the traffic is convenient, the distribution of population is sparseness in the hill and mountain where the accumulate temperature is lower and the hypsography is complex.2.

The eastern coast synthesizes economic zoneKey factors: GDP, area of plantation, and area of residential;Population model:y = 126.953x₁^0.5595+26.233x₂^0.4423+370.872x₃^0.3567(x₁ is GDP, x₂ is area of plantation, x₃ is area of residential) The result of T test: the value of sig is 0.290 which is bigger than 0.05, the value of F is 1.147, and the value of R² is 0.6668;The characteristic of population distribution: the whole distribution of population is denseness, especially more denseness in the zone where the traffic is convenient and economic is develop.4. The south coast synthesizes economic zone,Key factors: GDP, area of water and area of residential;Population model: y= 0.147x₁+176.828x₂^0.3658+6.3375x₃^0.5914+140903.47( x₁ is GDP, x₂ is area of water, x₃ is area of residential)The result of T test: the value of sig is 0.281 which is bigger than 0.05, the value of F is 1.181, and the value of R² is 0.6915;The characteristic of population distribution: the distribution of population is denseness in the zone where the distribution of inland-river is denseness and the accumulative temperature is lower, and sparseness in the hill and lowland where the accumulative temperature is higher.5. The middle reaches of Yellow River synthesizes economic zoneKey factors: GDP, DEM and area of residential;Population model:y = 34.831x₁^0.7008+261398e^-0.0012x₂+0.000625x₃ + 47062.5(x₁ is GDP, x₂ is DEM, x₃ is area of residential)The result of T test: the value of sig is 0.318 which is bigger than 0.05, the value of F is 1.004, and the value of R² is 0.8271;The characteristic of population distribution: the distribution of population is denseness in the altiplano and basin where hypsography is evenness and traffic is convenient, and sparseness in the hill and in the western of Inner Mongolia.6. The Middle reaches of Yangtze River synthesizes economic zoneKey factors: GDP, area of water and area of plantation;Population model:y= 0.284x₁ +0.000576x₂ +0.000217x₃ +328599.9( x₁ is GDP, x₂ is area of water, x₃ is area of plantation)The result of T test: the value of sig is 0.121 which is bigger than 0.05, the value of F is 2.439, and the value of R² is 0.4624;The characteristic of population distribution: the distribution of population is denseness in the zone where the distribution of inland-river is denseness, the agriculture is develop and the traffic is convenient, and sparseness in the hill and mountain.7. The big southwest synthesizes economic zoneKey factors: GDP, DEM and area of plantation;Population model:y=65.632x₁^0.664+174383e^-0.0006x₂+45875.2e^10-9x₃( x₁ is GDP, x₂ is DEM, x₃ is area of plantation)The result of T test: the value of sig is 0.108 which is bigger than 0.05, the value of F is 2.629, and the value of R² is 0.8764;The characteristic of population distribution: the distribution of population is denseness in the plain and basin where the hypsography is evenness and the agriculture is develop, and sparseness in the hill and mountain where the hypsography is complex.8. The big northwest comprehensive economic zoneKey factors: GDP, DEM, area of plantation and area of residential;Population model:y=20.286x₁^0.7178+104553.4e^0.0006x₂+11011.44e^10-9x₃+10908.03e^2*10-8x₄ (x₁ is GDP, x₂ is DEM, x₃ is area of plantation, x₄ is area of residential)The result of T test: the value of sig is 0.163 which is bigger than 0.05, the value of F is 1.976, and the value of R² is 0.6608;The characteristic of population distribution: the distribution of population is denseness in the altiplano and basin where the climate is warmth, the altitude is lower and the hypsography is evenness, and sparseness in the zone where the climate is bad and the altitude is higher.
