土地利用变化对植被净初级生产力影响研究

Study on the Effect of Land Use Change on Net Primary Productivity of Vegetation

基于遥感影像的土地利用变化生态环境效应是当前学者们关注的热点问题。开展土地利用变化对植被净初级生产力(NPP)研究,对于认识人类活动对生态环境影响具有重要意义。本研究以贵州省为例,采用2000年和2020年土地利用数据和2000-2020年MODIS遥感影像数据,利用线性回归方法,分析了2000-2020年贵州省土地利用变化特征及其对植被NPP变化影响。研究结果认为应该控制城市扩张规模,加强城市生态建设。

The ecological and environmental effects of land use change based on remote sensing images is a hot issue for current scholars. The study of land use change on net primary productivity(NPP) of vegetation is of great significance for understanding the impact of human activities on the ecological environment. Taking Guizhou Province as an example, this study uses land use data from 2000 and2020 and MODIS remote sensing image data from 2000 to 2020 to analyze the characteristics of land use change and its impact on vegetation NPP change in Guizhou Province from 2000 to 2020 using linear regression method. The research results suggest that the scale of urban expansion should be controlled and urban ecological construction should be strengthened.
