| 英文摘要 | Identifying and monitoring the spatiotemporal patterns of potentially contaminated land (PCL) in China is a key concern of ecological governance. However, the dynamics of PCL's expansion remain unclear nationwide. Integrating high-resolution remote sensing images, a land-use/cover change database, crawler data from websites, and other multisource data, we produced a new dataset of China's PCL in 1990, 2000, 2010, and 2020 using data fusion technology. Then we analyzed the spatiotemporal patterns of China's PCL from 1990 to 2020. Our study shows that the acquired vector dataset of China's PCL is of high quality and reliability, with an overall accuracy of 93.21%. The area of China's PCL has kept growing for the past 30 years, and the growth rate was especially rapid during 2000-2010, 2.32 and 6.13 times as rapid as that during 1990-2000 and 2010-2020, respectively. PCL has also been trending toward higher aggregation over markedly enlarged areas and has transferred progressively from north and southeast of China to northwest and southwest of China and Qinghai-Tibet Plateau. The patterns of China's PCL have been driven by the joint factors of policies, mineral resources, economy, and others, among which policies and the economy have contributed more prominently to the long-term transition. Our study promotes the access to high-quality spatial data of PCL to facilitate environmental governance of mine wastes, pollution and land management. |
