摘　　要：黄土高原是我国重要的生态区。通过遥感数据对黄土高原地区2001—2016年植被覆盖度的变化特征以及气候因子和人类活动对其的影响作用进行研究。结果表明:黄土高原植被覆盖度总体上呈现增长趋势,生长季明显增加;黄土高原植被覆盖度整体上与气温呈弱相关或负相关的关系,黄土高原植被覆盖度大体上与降水量呈现正相关的关系;其中耕地、林地、草地三种土地利用方式的植被覆盖度整体上升,水域、建设用地及未利用地三种土地利用方式的植被覆盖度总体下降。The Loess Plateau is an important ecological zone in China.The changes in vegetation coverage were investigated in the Loess Plateau region from 2001 to2016,as well as the impacts of climatic factors and human activities on it.The result shows that the vegetation coverage in the Loess Plateau has generally exhibited an increasing trend,with a significant extension of the growing season.Overall,the vegetation coverage in the Loess Plateau has a weak or negative correlation with temperature,while it shows a positive correlation with precipitation.Among different land use types,the vegetation coverage of arable land,forest land and grassland has generally increased,whereas the vegetation coverage of water bodies,built-up areas and unused land has decreased overall.
