Abstract


Vegetation photosynthesis , water is indispensable , irreplaceable raw material . Water is one of the main factors affecting plant photosynthesis and biomass . Vegetation water can reflect the state of growth of vegetation , wherein the water content of the crop , but also reaction crop yields . Based on the Changbai Mountain area in the study area , the Changbai Mountains in Jilin Province is located in the Southeast , the Changbai Mountain Nature Reserve is one of China 's largest natural environment and ecosystems best preserved forest ecosystems in protected areas . More than a century , under the influence of human activities and global climate change , the Changbai Mountain region face problems including forest resources change , volcanic activity and other disaster risk as well as international river water resources, ecological security . In this study, the MODIS image time series to establish vegetation water content model , the spatial and temporal characteristics of Changbai Mountain region 2001 and 2008 vegetation moisture content changes and trends quantitative research analysis and regional ecological security assessment for the Changbai Mountain area in the global climate change response etc. to provide basic information and basis . This thesis is divided into five chapters , the first chapter elaborate research background and significance , domestic and foreign remote sensing of vegetation moisture monitoring Research and Progress . The second chapter describes the natural environment of the Changbai Mountain area and geographical characteristics . Chapter III describes the data sources and research methods . Chapter clarifies the study area vegetation moisture dynamic characteristics of the spatial and temporal the the vegetation moisture distribution characteristics , analysis of vegetation moisture factors and trends as well as the different types of vegetation cover . Chapter conclusions.
