天津海河中游区域开发环境容量与环境影响分析

Environmental Capacity and Environment Impact Analysis of the Development of Tianjin Haihe River Middle Section

环境容量分析是区域环境规划与评价的基础.在对天津海河中游区域环境容量分析的基础上对开发活动将造成的环境影响进行了分析.分析结果表明,天津海河中游区域已经没有水环境容量,区域开发活动将进一步加剧天津海河中游区域水资源供应危机,开发活动排放的化学需氧量、氨氮和工业废气将导致水环境、大气环境进一步恶化.根据优化模拟结果,提出了产业结构优化建议以及应对水环境危机和大气环境危机的建议.

Environmental capacity analysis is a basis of the planning and assessment of the regional development.Based on environmental capacity analysis of Tianjin Haihe river middle section development planning,we conducted environment impact analysis of that area.The results show that：There has been no more water environmental capacity for the development of that area.And further development will worsen the water supply crisis.The bad water environment will be aggravated by COD and ammonia from waste water and the atmosphere environment will be aggravated too by industrial waste gas.Based on the optimized modeling analysis, some advice has been given in this paper to optimize industrial structure,relieve water crisis and improve the quality of atmospheric environment.
