湖北省环境质量现状及其变化趋势分析

Analysis for the Present Environmental Quality and Its Tendency of Hubei Province

从环境空气质量、地表水环境质量、城市声环境质量等方面,评述了湖北省环境质量现状,并结合历年监测数据、污染物排放情况及环保措施等方面,研究了2005～2014年全省空气和地表水环境质量变化趋势.结果表明,湖北省城市空气中NO2和PM10浓度呈上升趋势,PM25污染问题突出;地表水环境质量由轻度污染升至良好,近年来稳定在良好水平,但生活污染排放愈加严重,使水质现状较差水体改善存在较大压力.预计下阶段空气质量有所改善,但明显改善的压力较大;地表水环境质量总体保持稳定,但部分支流及城市内湖污染较重等问题仍将存在.

The status of environmental quality in Hubei Province was reviewed from aspects of ambient air quality, surface water quality, ur- ban sound environmental quality. Combined with years of monitoring data, pollutant emissions and environmental protection measures and oth- er aspects, the variation trend of air and surface water quality during 2005-2014 was studied. The results showed that： the city of Hubei Prov- ince NO2 and PM10 concentrations in the air rise, PM2.5 pollution problems highlighted; surface water quality increased from light pollution to good, stable at a good level in recent years, but life pollution discharge has become increasingly serious to make the water situation poor. The next phase of air quality is expected to improve, but the pressure of greater improvement is significant; surface water quality remained stable overall, but some tributaries and city inner lakes pollution problems still exist.
