| 摘 要： | 新疆森林主要有落叶针叶林、常绿针叶林、落叶阔叶林以及特殊灌木林4种类型,面积约为全疆植被面积的2%,但新疆森林在经济、社会和生态效益等方面却发挥着重要的作用.不同森林类型具有不同的NDVI变化特征,利用GIMMS NDVI数据集首先对新疆植被进行专家分类,然后分析近25年来新疆森林面积、蓄积量和密度的动态变化及其可能原...

| Abstract: | Four types of forests (i.e.,deciduous coniferous forest,evergreen coniferous forest,deciduous broadleaved forest and shrub) are distributed in Xinjiang. Forest coverage is only 2% of vegetation area,but the forests play an important role in social effects,economic returns and ecological benefits. The forests in Xinjiang were firstly classified with an expert classification method based on the seasonal change of NDVI curves of the forest types and the GIMMS NDVI datasets during the periods of 1982-1984,1984-... |
