| 摘 要： | 利用NOAA/AVHRR的NDVI数据和地面气象观测数据，以植被覆盖率和年沙尘暴日数为指标，分析了内蒙古中西部地区植被覆盖与沙尘暴分布的关系。研究结果表明，在内蒙古中西部地区，80年代沙尘暴日数的正距平与植被覆盖率的负距平、90年代沙尘暴日数的负距平与植被覆盖率的正距平是相互对应的；沙尘暴日数与植被覆盖率之间呈现负的相关关系，这种相关关系在不同地貌类型区和不同季节有所差异；沙地区的夏季（7、8、9月平均）植被覆盖率与第 2年沙尘暴日数之间的负相关最为显著。 |

| Abstract: | An analysis on the relationship between percentage of coverage of vegetation and days of sandstorm in central and western Inner Mongolia autonomous region is performed in this paper, taking percentage of coverage of vegetation and days of sandstorm as indexes and using the NDVI data of NOAA/AVHRR and meteorological observation data from earth surface. The study shows that in this area : (1) Positive anomaly of days of sandstorm matches with the negative anomaly of percentage of coverage of vegetation in 1980’s and negative anomaly of days of sandstorm matches with the positive anomaly of percentage of coverage of vegetation in 1990’s. (2) There is a negative interrelation between the days of sandstorm and the percentage of coverage of vegetation, which varies due to the difference of geomorphic feature and the changes of season. The negative interrelation between the percentage of coverage of vegetation in summer(July、August and September) in sand-covering area and the days of sandstorm in the next year is of the most markedness. |
