生态生态学生态生态学
气候变化研究气候变化研究

背景情况:

煤炭开采严重扰乱生态系统,并影响区域碳池.
评估采矿对碳库存的影响对于减缓气候变化和实现碳中和目标至关重要.
现有的研究往往忽视了地表干扰对土地利用变化预测和回收利用碳恢复潜力的影响.

研究的目的:

构建一个模型框架 (PIM-PLUS-INVEST) 来评估煤炭开采和土地回收对碳储存的影响.
量化分析山东省51个煤矿的碳储存变化.
为生态恢复责任和矿区的可持续土地管理提供科学参考.

主要方法:

开发了PIM-PLUS-INVEST模型框架.

Regression Analysis

Regression Analysis

Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
