京津冀地区人口与GDP增长对土地利用/土地覆被变化的影响

Impacts of Growth in Population and GDP on Land Use/Land Cover Change in Beijing-Tianjin-Hebei Region

本文使用中国土地利用遥感监测数据提取并分析了2000年、2005年、2010年和2015年京津冀地区土地利用/土地覆被变化,使用国家统计局所提供的人口和GDP数据分析了京津冀地区2000-2018年人口和GDP的变化。结果发现京津冀地区的土地利用类型与经济发展指标GDP同步变化,其中建设用地增长和耕地减少尤为明显,并与人均GDP增长显著相关。京津冀三地经济发展不平衡、人口吸纳能力的差异是土地利用变化差异较大的部分原因。随着京津冀协同发展的进行,未来该地区土地利用/土地覆被变化将更趋合理有序。

In this paper,remote sensing monitoring data of land use in China were used to extract and analyze land use/land cover changes in the Beijing-Tianjin-Hebei region in 2000,2005,2010 and 2015,and population and GDP data provided by the National Bureau of Statistics were used to analyze population and GDP changes in the Beijing-Tianjin-Hebei region from 2000 to 2018.The results show that the land use type in the Beijing-Tianjin-Hebei region changes synchronously with the GDP of the economic development index,among which the growth of construction land and the decrease of cultivated land are particularly obvious and significantly correlated with the growth of per capita GDP.The imbalance of economic development and the difference of population absorbing capacity among the three areas are part of the reasons for the difference of the change in land use.With the coordinated development of Beijing-Tianjin-Hebei region,land use/land cover changes in the future will be more reasonable and orderly.
