| 摘 要： | 针对我国局部区域的植被覆盖度与气候变化研究仍然较少的现状,该文以四川盆地为例,利用MODIS高光谱数据,以植被覆盖度作为监测植被动态变化指标,根据皮尔逊相关系数分析植被覆盖度与气候的相关性,总结2003—2010年四川盆地植被覆盖度动态变化趋势,研究温度变化对植被覆盖度的影响。研究表明:植被覆盖度与温度为极强正相关,除地震等特殊情况,两者变化趋势相似,夏高冬低。

| Abstract: | In view of the situation that research on vegetation cover change and climate change is less this paper took Sichuan Basin as an example and analyzed the correlation between vegetation coverage degree and temperature according to Pearson correlation coefficient using MODIS hyperspectral data and vegetation covering degree as an index of monitoring the dynamic changes of vegetation.Finally,this paper summarized the trends of vegetation cover changes in Sichuan Basin from 2003 to 2010,and studied the effect of temperature variation to vegetation coverage.Studies showed that the relation between vegetation cover degree and temperature was strong positive correlation,and their variation trends were similar excepting some special circumstances like earthquake,the trend was high in summer while low in winter. |
