Abstract

The classification of Köppen climate type has been widely used to identify regional climate change. This study investigated the changes of Köppen climate type over China during 1964 2015. On average, the arid climate was located in the northwest, tropical climate, temperate climate, and cold climate were distributed in the east from south to north along the latitude, and polar climate was concentrated on the Tibetan Plateau. Comparing Köppen climate types during 1964 1989 and 1990 2015, we found that cold climate with dry winter was replaced by a cold steppe climate in Northeast China and North China, warm summer was replaced by cold summer in Northeast China and the Tibetan Plateau, tundra climate was substituted by cold climate in the Tibetan Plateau, and cold climate was replaced by temperate climate in Central China and East China. Our results showed that the arid climate expanded eastward and southward, which may have resulted from a decrease in precipitation. Owing to the increase in temperature, the climate zones moved northward. This study provides valuable insights for government decision-makers in formulating crop planting systems, water resource management, and land use planning.

中国Köppen气候类型的时空变化

Köppen气候类型的分类已被广泛用于区域气候变化的识别。研究了1964 - 2015年中国Köppen气候类型的变化。西北地区平均为干旱气候，沿纬度自南向北向东分布为热带气候、温带气候和寒冷气候，极地气候集中在青藏高原。对比1964 - 1989年和1990 - 2015年Köppen气候类型发现，东北和华北地区冬季干燥的寒冷气候被寒冷的草原气候所取代，东北和青藏高原的夏季温暖气候被夏季寒冷气候所取代，青藏高原的冻土带气候被寒冷气候所取代，华中和华东地区的寒冷气候被温带气候所取代。结果表明，干旱气候向东和向南扩展，这可能与降水减少有关。由于气温升高，气候带向北移动。该研究为政府决策者制定作物种植制度、水资源管理和土地利用规划提供了有价值的见解。文章历史:2021年6月21日收稿2021年9月15日修订2021年10月18日接受

期刊介绍： The major publication of the Chinese Geoscience Union (located in Taipei) since 1990, the journal of Terrestrial, Atmospheric and Oceanic Sciences (TAO) publishes bi-monthly scientific research articles, notes, correspondences and reviews in all disciplines of the Earth sciences. It is the amalgamation of the following journals: Papers in Meteorological Research (published by the Meteorological Society of the ROC) since Vol. 12, No. 2 Bulletin of Geophysics (published by the Institute of Geophysics, National Central University) since No. 27 Acta Oceanographica Taiwanica (published by the Institute of Oceanography, National Taiwan University) since Vol. 42.
