| 摘要: |
| 【目的】研究2002—2015年蒙古高原植被短期稳定性对陆地水储量与气象要素的响应。【方法】利用GIMMS NDVI、月陆地水储量距平TWSA、气温和降水量，引入自回归模型量化2002—2015年蒙古高原植被稳定性对陆地水储量距平值（TWSA）和气象要素的短期异常响应。【结果】蒙古高原植被NDVI与气温和降水具有较强的相关性，植被NDVI与TWSA相关性强的区域主要分布在蒙古高原中部腹地区域。几乎所有的植被类型像素都表现出强烈的恢复力稳定性，其中恢复力稳定性较强的区域分布在蒙古高原东北部、北部以及内蒙古中部；林地、草甸草原和典型草原都表现出较强的恢复力稳定性。研究区大多数地区都表现出对TWSA抵抗力稳定性不显著，仅有33.1%的植被像素表现出对TWSA显著的抵抗力稳定性，植被抵抗力稳定性显著区域主要分布在蒙古高原中部、东部以及西北部的典型草原和荒漠草原区。【结论】自回归模型可定量描述蒙古高原植被稳定性对陆地水储量与气温和降水变化的响应关系，具有较好适用性；蒙古高原地区除了受降水和气温共同影响以外，陆地水储量在某些区域更能决定研究区植被生长状况。 |

| Abstract: |
| 【Objective】This study aims to analyze the impact of vegetation stability on water storage and meteorological factors in the Mongolian plateau.【Method】The analysis was based on data measured from 2002 to 2015. The GIMMS NDVI, monthly total water storage anomaly (TWSA), temperature, rainfall, and the autoregressive model was used to quantify the short-term impact of vegetation stability on TWSA and meteorological factors. 【Result】The vegetation index NDVI in the plateau exhibited a strong correlation with temperature and precipitation. The areas that have strong correlation between NDVI and TWSA are primarily located in the central areas in the plateau. Most vegetation types show strong stability resilience, particularly in the northeast, north, and center of the plateau. Woodland, meadow steppe, and typical grassland exhibited strong stability resilience. Most areas showed insignificant stability resistance to TWSA, and only 33.1% of vegetation exhibited strong stability resistance to TWSA. The areas with significant vegetation stability resistance were in the center, the east, and typical grassland and desert steppe areas in the Northwest. 【Conclusion】 The autoregressive model effectively represents the response of vegetation stability to water storage and meteorological factors in the plateau. The combined influence of precipitation and temperature plays a significant role in vegetation growth; areas with high water storage have a greater impact on vegetation in the plateau. |
