中国与欧美非道路移动机械排放标准对比分析

随着非道路移动机械保有量与使用量的不断增加,其排放造成的环境问题日益严重,相关的防治策略研究亟待加强。本研究首先总结了中国与欧美对非道路移动机械类型的划分方式及标准;其次,对中国与欧美的非道路移动机械排放标准进行归纳;最后,对现行中国与欧美的非道路移动机械排放标准进行了全面对比分析,分析发现,国内标准与欧美标准之间仍存在显著差距,以期为国内制定科学的非道路移动机械排放标准提供参考,为污染物防治策略的制定提供理论支撑。

Comparative Analysis on the Emission Standards of Non-road Mobile Machinery in China, the Europe and the US

The coordinated development of Beijing-Tianjin-Hebei, the Yangtze River Economic Zone, the Belt and Road, Guangdong-Hongkong-Macau Greater Bay Area, and Xiongan New Area are the key strategic areas of China in the future "14th Five-Year", and will become the four engines of China''s economic and social development in the new era. Based on the analysis of the imbalance and diversity of urban population, economy and pollution distribution in China from the perspective of city, the basis and criteria for identifying the core issues of the division of ecological environment in the national strategic region were found based on existing empirical research findings. The main environmental problems in the five national strategic regions are put forward, and the regionalized ecological management strategies are put forward.
