【摘要】：承载力是描述环境资源与社会经济发展之间关系的重要指标,是在承载力限制下协调社会经济发展与资源环境保护的有效手段。基于此,采用系统动力学方法,构建地表水环境承载力模型,以四平市地表水环境承载力为例分析水环境承载力的影响因素构成及其影响的显著性大小。结果显示,人口数量的变化是地表水环境承载力的主要影响因素;农业生产是影响地表水资源消耗量的主要因素;第二产业总产值是影响地表水环境中COD含量的重要因素。因此,可通过调整人口数量、农业生产投入与第二产业投入与结构实现地表水环境与社会经济发展的平衡,使其在地表水环境承载的范围内协调发展。
[Abstract]:Bearing capacity is an important index to describe the relationship between environmental resources and social economic development. It is an effective means to coordinate social and economic development and environmental protection under the limit of carrying capacity. Based on this, the surface water environmental carrying capacity model is constructed by using system dynamics method. Taking the surface water environmental carrying capacity of Siping City as an example, the influence factors of water environmental carrying capacity and its significance are analyzed. The results show that the change of population is the main influencing factor of surface water environmental carrying capacity, the agricultural production is the main factor affecting the consumption of surface water resources, and the gross output value of the second industry is the important factor that affects the COD content in the surface water environment. Therefore, the balance of surface water environment and social economic development can be achieved by adjusting the population number, agricultural production input and secondary industry input and structure, so that they can develop harmoniously within the range of surface water environment carrying capacity.
