摘  要：
内蒙古中部农牧交错区域生态系统比较脆弱,气候影响下的植被覆盖度变化和气象驱动力是该地区生态系统变化的主导因子。基于遥感MOD13 A2获取内蒙古中部2000-2012年归一化植被指数(NDVI)数据,监测近13年内蒙古中部植被覆盖度变化,并对与植被生长相关的气象因子进行相关性分析。结果表明,2000-2012年内蒙古中部平均植被覆盖度在波动中呈现缓慢增长的趋势,平均每年增长1.29个百分点;覆盖度变化与年降雨量和7、8月降雨量呈极显著正相关,与7、8月平均温度呈显著负相关,与年均温度、风速相关程度低。

摘  要：
Farming-pastoral zone in ecological system of middle Inner Mongolia was fragile. Under the influence of climate,vegetation coverage change and weather driving force was the dominant factor of the region ecosystem changes. Based on remote sensing MOD13A2 in central Inner Mongolia from 2000 to 2012, the normalized difference vegetation index(NDVI) data, the vegetation coverage change in middle Inner Mongolia for nearly 13 years were monitored. The vegetation growth related meteorological factor was analyzed. The results showed that the average vegetation coverage in the middle of Inner Mongolia from 2000 to 2012 had a slow growth in waves, with the average annual growth of 1.29 percentage points. Coverage change was positively correlated with rainfall, negatively correlated with average temperature in July and August, and less correlated with annual average temperature and wind speed meteorological factors.
