摘要
水环境问题已成为制约人类可持续发展的瓶颈。构建了基于水资源相关子系统、社会经济相关子系统和水污染控制相关子系统耦合的水环境承载力综合评价指标体系,并对辽宁铁岭的水环境承载力进行综合评价。结果表明:铁岭各县(市、区)的水环境承载力变化趋势大致相同,2012、2013年水环境承载力相对较好,处于轻度超载状态或中度超载状态,2014、2015年降到了中度超载状态或严重超载状态,而2016年又恢复至中度超载状态。铁岭的水环境承载力主要与水资源相关子系统和水污染控制相关子系统相关。水环境承载力的评估将为铁岭制定水环境保护政策提供科学依据。
Water environmental problem has become the bottleneck of human sustainable development.A water environmental capacity evaluation index system was constructed by coupling water resources sub-system,social economy sub-system and water pollution control sub-system,and it was applied to evaluate water environmental capacity for Tieling of Liaoning.Results showed that the water environmental capacity variation of Tieling was similar.The water environmental capacity in 2012 and 2013 were relatively good,at slightly overloaded state or moderately overloaded state.That in 2014 and 2015 decreased to moderately overloaded state or severely overloaded state.However,that in 2016 recovered to moderately overloaded state.The water environmental capacity for Tieling was mainly determined by water resources sub-system and water pollution control sub-system.The evaluation results would provide a scientific basis for Tieling to formulate water environmental protection policies.
