近地表风速（SWS）的变化是由人类活动和自然气候变化的共同作用引起的，因此研究近地表风速的长期变化及其原因对于认识自然变化和人类活动对近地表风速的影响具有重要意义。一些研究表明，过去30年中国的土地利用和覆盖变化（LUCC）非常明显。然而，LUCC 对 SWS 放缓的可能影响仍不确定。欧洲中期天气预报中心自1989年1月起（将延期至1979年1月）（ERA-Interim）数据集包含的土地利用和覆盖变化信息很少，因此利用ERA-Interim数据集的土壤覆盖率与492个气象站的土壤覆盖率之间的差异来估算1979-2010年中国土地覆盖面积变化对SWS的影响。结果显示如下。 (1) LUCC 对 SWS 的影响是明显的，可能导致 SWS 每十年减少 0.12 m s–1，这可以解释大城市和小城市的风速分别减少 0.57 和 0.30 m s–1。此外，城市化率提高10%可能会导致SWS减少0.1 m s–1。 (2) 京津唐地区、长三角地区和珠三角地区土地利用变化对SWS的影响比整个地区更为显着。 (3) ERA-Interim数据集的偏差可能导致研究期间整个区域的估计出现51%的误差，但对SWS的下降趋势影响不显着。基于传统观测减去再分析方法计算的LUCC引起的SWS减少率误差为0.01 m s–1 decade–1。 (4)本研究还比较了不同方法量化LUCC对SWS影响的结果。
The changes of near-surface wind speed (SWS) were induced by the combination effects from anthropogenic activities and natural climate changes, thus the research of the long-term changes and cause of SWS is very important to recognize the effects from natural changes and anthropogenic activities to SWS. Some studies have shown that land use and cover change (LUCC) over China was very distinct in the last 30 years. However, the possible effects of LUCC to the slowdown in SWS are still uncertain. The European Centre for Medium-Range Weather Forecasts Reanalysis from January 1989 onward (to be extended back to January 1979) (ERA-Interim hereafter) dataset includes little information about LUCC, so the effects of LUCC on SWS in China during 1979–2010 have been estimated by using the difference between SWS per the ERA-Interim dataset and that from 492 meteorological stations. The results show the following. (1) The effects of LUCC on the SWS are distinct, and could have caused a decrease in the SWS of 0.12 m s–1 per decade, which could account for decreases of 0.57 and 0.30 m s–1 wind speed for large and small cities, respectively. In addition, a decrease of 0.1 m s–1 in the SWS could be induced by a 10% rise in the urbanization rate. (2) The impacts of LUCC on the SWS in the Beijing-Tianjin-Tangshan region, the Yangtze River Delta region and the Pearl River Delta region are more significant than those for the entire region. (3) The bias in the ERA-Interim dataset could cause a 51% error in the estimation for the entire region during the study period, but had a non-significant effect on the decreasing trend in the SWS. The decrease rate of SWS induced by LUCC based on the traditional observation minus reanalysis method had an error of 0.01 m s–1 decade–1. (4) The results of different methods to quantify the impacts of LUCC on the SWS are also compared in this study.
