2000–2015年中国城市化进程中耕地质量及其时空变化研究（英文）
|
摘要
加速的城市化进程导致越来越多的耕地被占用,在耕地资源供给不足情况下高质量的农田受到巨大威胁,进而可能对中国粮食安全构成威胁。尽管已对中国耕地质量的空间格局进行了评估,但其随时间变化的情况未见报导。本研究利用MODIS的净初级生产力产品(MOD17)数据,基于发展的累积概率分布法确定耕地质量标准,以2000–2005年、2005–2010年和2010–2015年三期基于Landsat遥感的土地利用变化(LUCC)数据,得到低、中、高质量农田的空间分布,定量分析城市化占用耕地的数量和质量。结果表明,城市化占用耕地面积占耕地减少总面积的比例由2000–2005年的47.29%增加到2010–2015年的77.46%。2000年,中国耕地质量以中低产田为主,分别占全国耕地面积的40.81%和48.74%,高产田仅占10.44%。随着建设用地规模的扩大,城市化占用高产田面积在全国耕地面积中的比例从2000–2005年的9.71%上升到2010–2015年的15.63%,高产田受到严重威胁。从空间上看,该现象已由华东、华南向中西部地区转移,尤其是西北地区,其2010–2015年建设占用耕地面积中,高产田达到52.97%。本研究不仅提供了一种评价耕地质量的方法,同时揭示了城市化进程占用高质量耕地的趋势。未来占用高质量农田的趋势可能会持续,必须构建以振兴乡村为主的新型发展模式,可能是缓解土地资源紧缺情况下城市化和粮食安全矛盾的可选途径,值得土地利用规划和政府决策给予重视。
The acceleration of urbanization has led to the occupation of more cropland, especially higher quality cropland, which could pose a huge threat to food security and have other implications for the inadequate cropland resource supply in China. Though the spatial status of Chinese cropland quality has been assessed, its temporal changes since 2000 to 2015 are still not clear. An accumulated probability distribution method was used to determine the criteria of cropland quality using the net primary production data product(MOD17) from Moderate Resolution Imaging Spectroradiometer(MODIS). Then the cropland quality of higher, median and lower production was spatially mapped and its changes due to occupation by urbanization were analyzed through the land use changes(LUCC) data primarily from Landsat TM images in the three periods of 2000–2005, 2005–2010, and 2010–2015.The results showed that of the total cropland reduction area the proportion taken by urbanization increased from47.29% in the early stage to 77.46% in the recent period. The quality of Chinese cropland was dominated by lowand medium-yield fields, accounting for 40.81% and 48.74%, respectively, with high-yield fields accounting for only 10.44% of the total cropland in the country in 2000. The high-yield areas have been seriously threatened by the expansion of construction land fields, with the ratio of high-yield area to total area occupied by urbanization increasing from 9.71% in 2000–2005 to 15.63% in 2010–2015. Spatially, this phenomenon has been moving from eastern and southern China to central and western China, especially in Northwest China where the ratio has arrived at the highest proportion, with 52.97% of high-yield cropland in the total land taken by the expansion by 2015. This study not only provides a method to assess cropland quality but also reveals the threatening trend from the expansion of urbanization on high-quality cropland. More attention should be paid to the latter in land use planning and policies made to prevent threats to food security from declines in both cropland quantity and quality.
