考虑到“绿色长城”工程和未来气候变化，中国所在的河套平原西北部的植被预计将发生重大变化。在这项研究中，使用天气研究和预报模型来调查气候对规定的植被变化的响应。当NWHP中的植被从“裸露或稀疏植被”类别变为“草地”时，气候既表现为本地响应，也表现为远程响应。在当地，气温在冬天上升，但在夏天下降。夏季降水量大幅度增加，冬季略有增加，这主要是由于水汽含量增加和环流调整所致。此外，大气环流异常还导致远距离环流响应，包括中国中北部地区降水减少，中国中南部地区降水增加。这项研究的结果揭示了使用最先进的区域气候模型对西北太平洋地区植被变化的本地和远程气候响应。版权所有©2012皇家气象学会
Considering the ‘Green Great Wall’ project and future climate change, the vegetation in the Northwest Hetao Plain (NWHP) of China is expected to undergo considerable changes. In this study, the climatic response to prescribed changes in vegetation is investigated using the Weather Research and Forecasting model. When the vegetation is changed from ‘bare or sparsely vegetated’ category to ‘grassland’ in the NWHP, the climate shows both local and remote responses. Locally, the temperature increases in the winter but decreases in the summer. The precipitation level increases substantially in the summer while increases slightly in the winter, which is mainly caused by the increase in the amount of water‐vapour and circulation adjustment. Additionally, atmospheric circulation anomalies also lead to remote circulation responses, including a decrease in precipitation over Central North China and an increase in precipitation over Central and South China. The results of this study bring to light the local and remote climatic responses to changes in vegetation in the NWHP using a state‐of‐the‐art regional climate model.
