土地利用变化与施肥管理方式对黑土碳库的影响·英文版 内容简介

on the basis of the long-term position experiments established in the national field research station of agroecosystem in hailun, and key laboratory of black soil ecology of chinese academy of sciences, this research aims to examine the impact of land-use change and long-term fertilization on soil carbon stocks, the physically protected soc, and carbon emissions from black soil as well as carbon budget through the ecosystems and soil-plant-atmosphere interface. the stability mechanism of black soil carbon pool was defined, and carbon sequestration capacity of black soil was also evaluated.
