2000-2022年鄂尔多斯高原人类活动对植被覆盖变化的影响
Effects of human activities on vegetation cover changes in the Ordos Plateau during 2000-2022
摘要
Abstract
Monitoring the spatiotemporal characteristics of vegetation cover changes in the ecologi-cally fragile areas of China and revealing the spatiotemporal trajectory of the impacts of anthropo-genic activities on them are of great significance.The spatiotemporal changes in vegetation NDVI of human activities and vegetation in the Ordos Plateau are analyzed since the 21st century using the trend analysis and residual analysis methods based on land use data,vegetation cover,mete-orology and statistical yearbook data.The impacts of human activities on vegetation are then ex-plored.The results show an increase in the area of urban and rural built-up areas,cultivated land reclamation,and grassland caused by human activities in the Ordos Plateau.The vegetation ND-VI generally shows a fluctuating upward trend,with a rapid upward trend in 2011-2022.Hu-man activities change the vegetation cover through mining,reclamation and grazing,desertifica-tion transformation and afforestation.The proportion of areas where human activities positively impacted vegetation cover is 97.27％,while the negative impact is 2.73％.The results can pro-vide scientific references for the ecological protection of the Ordos Plateau and the establishment of national innovation demonstration zones for the sustainable development agenda.关键词
