环渤海地区县域土地——人口城镇化水平时空演化与失调发展特征
|
摘要
以多源遥感数据、GIS辅助数据和统计数据为基础,利用GIS空间分析法和指数分析法,揭示近20年来环渤海地区县域土地—人口城镇化水平时空演化与失调发展特征。结果表明:环渤海地区县域土地—人口城镇化水平均以低等水平为主,但土地城镇化处于中高等水平的县域多成组分布于市辖区周围,人口城镇化处于中高等水平的县域多连片分布于经济较为发达的地区;土地—人口城镇化水平均呈显著增长趋势,但土地城镇化水平呈高速增长的县域多分布于沿海地带和省会城市内,人口城镇化水平呈高速增长的县域主要分布于河北省内;约有94.56%的县域土地—人口城镇化水平呈失调发展,失调等级以轻度失调为主,失调类型以人口城镇化滞后为主;土地—人口城镇化水平失调发展呈周期性循环波动、螺旋式上升趋势,总体而言,重度失调发展的县域比例有所上升,人口城镇化滞后的县域比例显著上升。
Based on the multi-source remote sensing data, GIS ancillary data and statistical data, this paper revealed the spatial-temporal evolution and uncoordinated development characteristics of land-population urbanization at the county level in Bohai Rim region in the past 20 years using the methods of GIS spatial analysis and index analysis. The research results showed as follows; Firstly, the land and population urbanization levels of the counties both were mainly at the low level, but the counties with medium to high land urbanization level were mainly distributed around the municipal districts, while the counties with medium to high population urbanization level were mainly continuously distributed in the developed areas. Secondly, the land and population urbanization levels both presented a significant growth trend, but the counties with high growth of land urbanization level were mainly distributed in the coastal zones and the capital cities,while the counties with high growth of population urbanization level were mainly distributed in Hebei province. Thirdly,about 94.56% of the counties presented uncoordinated development between land and population urbanization and their uncoordinated grades were mainly mild disorder, most of the population urbanization level belonged to lag types.Fourthly, the uncoordinated level presented as cyclical fluctuation and spirally rising trend, and the proportion of severe uncoordinated development had a small increase, while the proportion of lag-type population urbanization had a marked increase. These findings could provide references for optimizing the pattern of urbanization and promoting the coordinated development of land-population urbanization.
