复合生态系统是由自然、环境和经济活动共同组合而成的生态功能统一体,协调处理好各子系统之间的关系有助于生态系统的可持续发展.本文论述了磷矿山复合生态系统及其组成要素和结构,并分析了复合生态系统的经济和生态功能,根据磷矿山实际运行情况从非线性机制、协同进化机制和反馈机制方面论述磷矿山生态系统的演化机制,引入Logistic曲线方程描绘磷矿山复合生态系统的运行轨迹.并运用数值模拟方法对绿化边坡进行分析,结果表明经过绿色矿山建设可以有效地防止滑坡的发生,提高生态系统的稳定性.
The compound ecosystem is a unified ecological function formed by the combination of natural, environmental and economic activities and it is helpful for the sustainable development of the ecosystem to co-ordinate the relationship between the various subsystems. And its components and structure, and analyzes the economic and ecological functions of the compound ecosystem. According to the actual operation of the phosphate mine, the evolution mechanism of the phosphate mine ecosystem is discussed from the aspects of nonlinear mechanism, co-evolution mechanism and feedback mechanism. Logistic The curve equation describes the trajectory of the complex ecosystem of phosphate rock and analyzes the green slope by numerical simulation. The results show that the landslide can be effectively prevented and the stability of the ecosystem can be improved through the construction of green mine.
