| 摘 要： | 基于时间序列遥感数据获取的多期土地覆被数据对中国人工表面变化信息进行提取和定量评价,进一步分析中国各省市的人均人工表面面积变化趋势,以及7个主要城市群的人工表面变化情况,结果可知:① 2015年中国人工表面的面积总和为29.07万km 2,其中建设用地25.10万km 2、交通用地3.09万km 2、采矿场0.88万km 2;② 2015年人工表面总面积较2010年年均增长为0.66万km 2,年均增速为2.57%,较2000~2010年年均增长0.55万km 2（年均增速2.70%）增速有所放缓。③ 总体上中国大部分行政区的人均人工表面面积近15 a持续提高。

| Abstract: | Chinese government pulished ‘National New Urbanization Plan (2014-2020)’ (Plan for abbr.) in 2014. In the Plan, some problems were proposed, including ‘urbanization of land’ is faster than the ‘urbanization of population’, and the extensive and inefficient use of settlements, ‘the potential of urbanization could be developed in middle-western China’, ‘Urban spatial distribution and scale structure are unreasonable, and do not match the resource and environmental carrying capacity’. Also, the Plan suggested ‘effectively controlling the scale of new construction sites in mega cities’. Based on the multi-temporal landcover data obtained from time series remote sensing data, this article extracts and quantitatively evaluates the information of built-up land changes nationwide. Based on this, the trend of changes in per capita built-up land area of all provinces across the country and the seven major Metropolitan region are further analyzed. The built-up land changes validate and support some standpoints in the Plan, and provide data support for the evaluation and planning of urbanization in China. According to the ChinaCover dataset, the total area of built-up land in China was 290 700 km2 in 2015, of which 251 000 km 2 for settlements, 30 900 km2 for transportation land, and 8 800 km2 for mining field. In 2015, the total area of built-up lands increased by an annual average of 6 600 km2 compared to 2010, with an average annual growth rate of 2.57%, which is an increase over the annual average increase of 5 500 km2 from 2000 to 2010, but the growth rate is a slowdown (2.70%). Overall, the growth rate of the built-up land in most provinces in China has continued to increase in the past 15 years. This reflects the ‘urbanization of land’ is faster than the “urbanization of population”, and the extensive and inefficient use of settlements. Meanwhile, the economic transition is proved by analyzing the relation between GDP and built-up lands, which shows the urbanization influences GDP more during 2000-2010 than 2010-2015. The rapid development of western provinces primarily shows the high urbanization potential of the middle and western China. The monitoring in the 7 major Metropolitan region indicates that the pace of urbanization in China has been accelerating in the past 15 years, and in particular, the expansion rates of some late developing Metropolitan region are mostly fast, while the rate of the developed Metropolitan region have slowed down due to the requirements such as ‘effectively controlling the scale of new construction sites in mega cities’, but the problem of ‘Urban spatial distribution and scale structure are unreasonable, and do not match the resource and environmental carrying capacity’ is still existing. |
