我国新型城镇化进程中土地污染研究进展
Research Progress on Land Pollution in New Urbanization Process in China

我国的新型城镇化建设使人口逐步由乡村向城市流动，人类所生存的土地也在发生变化。中国新型城镇化建设中的人口及土地变迁过程导致的土地污染都是威胁生态安全的最关键问题。本文通过系统性梳理我国新型城镇化进程中存在的四种发展形态，并重点阐述了不同发展形态下的土地污染水平和污染来源，为我国新型城镇化快速发展和生态文明建设提供借鉴。识别新型城镇化进程中土地污染演变规律、建立整个新型城镇化建设过程中的土地污染研究体系、从污染的机制剖析–效应评估–污染治理方面开展相应的土地污染治理，是保障我国新型城镇化建设的必需要素。
The construction of the new urbanization in China has caused the population to flow from coun-tryside to city, and the land where human beings live is also changing. The land pollution caused by population and land change in the process of China’s new urbanization is the most critical problem threatening ecological security. This paper systematically sorts out the four development forms in the process of China’s new urbanization, and focuses on the land pollution level and pollution source under different development forms, to provide reference for the rapid development of new urbanization and the construction of ecological civilization. Identifying the evolution law of land pollution in the process of new urbanization, establishing the research system of land pollution in the whole process of new urbanization construction, and carrying out the corresponding land pollution control from the aspects of the mechanism analysis, effect evaluation and pollution control are the essential elements to guarantee our new urbanization construction.
