| 摘 要： | 利用2000~2008年MODIS/NDVI数据,结合谐波分析、影像处理和基于像元的空间统计方法,分析了不同时间尺度下长白山地区的植被覆盖年内和年际变化与气温、降水的空间相关性。结果表明,近10 a来长白山地区气温和降水都均呈增加趋势;年内和年际变化过程中,长白山地区植被覆盖受气温影响的程度要高于降水;长白山地区春季和秋季植被覆盖与气温呈正相关,夏季主要呈负相关;不同月份的相关统计与年统计和分季节统计相比,更能细致地反映植被覆盖与气候的响应关系。

| Abstract: | The spatial correlation between intra-annual and inter-annual variation of the vegetation cover and climate change in the Changbai Mountain Area was analyzed by using the HANTS, imagery processing and pixels-based spatial statistical methods based on the MODIS-NDVI data from 2000 to 2008.The results showed that, the temperature and the precipitation in this area showed an increasing trend in recent 10 years. During intra-annual and inter-annual variation, the influence degree of temperature on the vegetation cover was higher than precipitation, and there was a positive correlation between the temperature and the vegetation cover in spring and autumn but negative correlation in summer. The statistics of monthly would reflect more detail response relation between the vegetation cover and climate change. |
