摘要(Abstract)：

为探索雄安新区的热环境变化,该文利用Landsat-8多光谱遥感影像,通过量化统计模型分析,实现了2013—2018年雄安新区NDVI变化对热环境影响分析。结果表明:从2013—2018年,雄安新区的NDVI呈现增加的趋势,高温区主要分布在新区的东北部裸露土地区域,中部和西南部人口活动密集的建筑区,约占15%;低温区分布在水体湿地区域,约占20%,NDVI与LST呈现明显负相关关系。6年时间新区的NDVI变化率基本稳定占57.96%,NDVI退化的占20.59%,NDVI改善的占21.55%,改善区主要分布在新区中部白洋淀湿地周边;LST变化率处于稳定的占59.00%,LST改善的占33.00%,改善区主要分布新区中部和白洋淀湿地周边,LST加剧的占8.00%,主要分布在人口密集的城市中心及热加工厂集中的地区。
