| Population urbanization and land urbanization is an important aspect of urbanization, and the coordination is the key factor to judge whether urbanization is health. Many scholars from various countries have carried out active researches on population urbanization and land urbanization coordination, but their researches are currently more concerned about the overall coordination of the national urbanization and urbanization of the total urban population, or a single land, and not on the overall analysis of the interior of the different units. Researching from different urbanization and in-situ urbanization perspective of a specific area in the same period of population urbanization and land urbanization coordination will be a new perspective.Poyang Lakeside area is an important part of social and economic development in Jiangxi province, it gathers as much as 28.91% of the population and created the entire province 34.80% of GDP with the 16.30% land area of entire province, and the poyang lakeside area urbanization has an important role in the urbanization of Jiangxi province. This paper based on Poyang Lakeside area as the study area, 1990, 1995, 2000, 1995, 2010, 2012, 6 remote sensing image, and through the research for the population of permanent residents in cities and towns as the main data source. Research the coordination of people urbanization and land urbanization in the process of the different urbanization and in-situ urbanization from 1990 to 2012(five years for a period of time) in Poyang Lakeside area, and analyze the cause of the disorder. At the same time, put forward the differential countermeasures to promote coordinated development both people urbanization and land urbanization in the process of the different urbanization and in-situ urbanization of Poyang Lakeside area. In view of the different urbanization, put forward the change of urban construction land "plane expansion" for the "internal tapping";Increasing urban industries, improve industrial park land use benefits, promote the development of city integration production; And for in-situ urbanization, to strengthen the infrastructure construction of the small towns; strengthening rural joint operation, to ensure security in situ urbanization new land index; Innovation of rural construction land circulation system, optimize the structure of regional rural land for construction purposes.Draw the following conclusion from research :(1)Poyang Lakeside area scale of urban population and urban built up area keep with synchronized growth trend from 1990-2012. Urban population increased from 3.1241 million in 1990 to 7.2572 million in 2012, increased by 4.1331 million during 23 years, increased by 132.30%,the average annual increase of 179700; At the same time, the urban area is increased from 28528.93 hectares in 1990 to 87557.82 hectares in 2012, increased 59028.89 hectares during 23 years, annual average increase of 2566.47 hectares, 1990-2012, urban area is the growth rate reached 206.91%, 135.47% higher than urban population growth rate, lakeside Poyang lake region in 1990-1990 urban built up area expansion speed significantly faster than urban population growth.(2)In the process of different urbanization from 1990 to 2012, the urban people keep with the urban built up area development trend of synchronous growth. Four downtown urban population increased from 1.4911 million of 1990 to 2.9314 million in 2012, increased by 1.4403 million, increase by 96.59%, the average annual increase of 62600; At the same time, the urban area is increased from 13079.09 hectares in 1990 to 43431.01 hectares in 2012, increased 30351.92 hectares during 23 years, annual average increase of 1319.65 hectares, 1990-2012, urban area is the growth rate reached 232.06%, 74.61% higher than urban population growth rate, Poyang Lakeside lake region in 1990-1990 in different towns built up area in the process of urbanization has expanded far faster than the speed of urban population growth.(3)During the year of 1990-2012,urban population in the process of urbanization and the city keep with the development trend of synchronous growth properly. 150 towns with urban population increased from 1.1067 million to 3.687 million, increased by 2.7603 million during 23 years, increased by 249.42%, the average annual increase of 120000; At the same time, the urban area is increased from 14701.48 hectares in 1990 to 37670.19 hectares in 2012, increased 22968.71 hectares, annual average increase of 998.64 hectares, 1990-2012, the growth rate of urban area is the 156.23%, lower 93.18% than urban population growth rate, Poyang Lakeside region in 1990-1990 in situ town built up area scale expansion speed in the process of urbanization is much slower than the speed of urban population growth.(4)During the year of 1990-2012, dispersion coefficient of population urbanization and land area is 0.22 in Poyang Lakeside, which belongs to the mild imbalance, and population urbanization lags behind the land urbanization. The results show that: ①1990-2012, most of the county(city, area) of the population urbanization and land were in a state of imbalance of urbanization, only three counties were coordinated development, the amount accounted for only 16.67% of the total. ② The city and its surrounding counties population urbanization were poor coordination of urbanization in the land. ③The spatial distribution of population urbanization and land urbanization coordinated with the northeast- southwest poor coordination, coordination characteristics of relative cheered on both sides. ④Most of the population urbanization laged behind the land urbanization, only four of the 18 counties county land urbanization lagging behind the population urbanization, accounting for 22.22% of the total.(5)The dispersion coefficient of population urbanization and land urbanization was 0.41 in the process of different urbanization from 1990 to 2012, belong to moderate imbalance, and population urbanization lags behind the land urbanization. At the same time, the dispersion coefficient of the population urbanization and land urbanization were basic rendering first rises after drop phenomenon dispersion in central city in each period.(6)The dispersion coefficient of population urbanization and land urbanization was 0.23 in situ urbanization process from 1990-2012, and belongs to the mild imbalance, land urbanization lagging behind the population urbanization. at the same time, the town’s population urbanization and land urbanization subtypes of coordination, experienced a process from the land urbanization lag model to the population urbanization lag model of transformation in situ urbanization process.(7)The coordination of people urbanization and land urbanization was not same between town and general town in the process of in situ urbanization. And the dispersion coefficient of town is 0.22, belongs to the mild imbalance, population urbanization laged behind the land urbanization. While the dispersion coefficient of general town was 0.41, belong to moderate imbalance, and the population urbanization lags behind the land urbanization. |
