内蒙草原区植被覆盖度时空演变及其驱动力分析
Spatial-temporal evolution of vegetation coverage and its driving force analysis in Inner Mongolia grassland
[目的]内蒙草原具有丰富的自然植被和矿产资源。以内蒙草原区为参考确定适宜的植被覆盖度并了解其分布特征和驱动因素,可为其矿山生态修复工作提供有益的思路和建议。[方法]本研究基于Landsat5/7/8 NDVI数据,采用像元二分模型反演植被覆盖度。通过Sen+MK和Hurst指数对该地区植物覆盖度的稳定性、空间分布和未来演变趋势进行了全面的研究。并且使用最优参数地理探测器(OPGD)来探究植被覆盖度空间分异的驱动因素。[结果]1)2006-2020…查看全部>>
[Objective]Inner Mongolia grasslands are rich in natural vegetation and mineral resources.Taking the grassland area of Inner Mongolia as a reference to determine the appropriate vegetation coverage and understand its distribution characteristics and driving factors can provide useful ideas and suggestions for its mine ecological restoration work.[Method]Based on the Landsat5/7/8 NDVI data,this study uses the pixel binary model to invert the vegetation covera…查看全部>>
