基于MODIS数据的都柳江流域2000-2021年植被覆盖度时空变化OA
Temporal and Spatial Changes of Vegetation Coverage in Duliu River Basin from 2000 to 2021 Based on MODIS Data
通过植被覆盖度变化所反映的生态环境改善或退化,以认识区域生态环境的演变特征.以都柳江流域为研究区,基于MODIS-NDVI产品数据,利用像元二分模型计算流域植被覆盖度状况;通过趋势分析、距平百分率及变异系数分析22 年来流域植被覆盖度变化趋势、波动及异常情况.结果表明:①都柳江流域植被覆盖度整体为较高覆盖度及高覆盖度,植被覆盖度良好且季节分布特征显著;②植被覆盖度变化趋势主要以增加趋势为主,夏季变化趋势与年际变化趋势相似度高,春季则与冬季变化趋势…查看全部>>
Changes in vegetation coverage can reflect the improvement or degradation of the ecological environment,so as to help identify the evolution characteristics of the regional ecological environment.This paper takes the Duliu River Basin as the research area and calculates the vegetation coverage condition of the basin by using a pixel binary model based on MODIS-NDVI product data.The changing trend,fluctuations,and abnormal conditions of the vegetation coverag…查看全部>>
