遥感技术与陆地生态系统碳循环研究

在人类社会日益关注全球环境问题的今天,大气中CO2和CH4等温室气体浓度升高诱发的全球气候变化已成为可持续发展的最严峻挑战。因此,针对各个陆地生态系统的碳循环研究成为气候变化和区域发展研究的重点和关键。陆地生态系统中土地利用方式、植被种类等的变化,通过时间和空间的尺度来影响着全球碳循环,而遥感技术具有宏观、速度快、周期短、信息量大、多时相等特点,因此在植被覆盖和土地利用分类、碳循环遥感模型等方面都有着重要的应用。

Remote Sensing Technology and Research on Terrestrial Ecosystem Carbon Cycle

Nowadays,human community is becoming increasingly concerned about global environmental issues,atmospheric greenhouse gases,such as carbon dioxide and methane have concentration-induced global climate change,and it has become the most serious challenge to sustainable development.Therefore,the carbon cycle research for each terrestrial ecosystem has become the emphases and key focus of climate change and regional development.Land-use patterns,changes in vegetation types,etc.of the terrestrial ecosystems influence the global carbon cycle through time and space scales.Remote sensing technology has special characteristics,such as macro scale,speedy,cycle short,informative,temporal,and plays a very important role in vegetation cover and land use classification、carbon cycle models and other aspects.
