湖南省生态环境变化及驱动机制

分析了湖南省生态环境变化的总体特征：水土流失加剧，土地资源退化严重；林地面积减少，森林质量下降；动植物物种减少，一些珍稀物种难见踪影；天然湿地面积减少，湖泊水质污染加重，氮磷浓度越来越高；城镇空气质量总体基本稳定，江河水质污染普遍，噪声处于中等污染水平；农村化学用品的使用量逐年上升，环境污染愈加严重。人口大幅度增长和经济的非持续发展方式是其直接原因，要坚定不移地走社会经济可持续发展道路，从根本上解决高环境代价式的经济发展与掠夺式资源开发造成的生态环境问题，实现资源环境与经济社会的可持续发展。

The Ecological Environment Degradation and Driving Mechanism of Hunan

The total characteristic of ecological environment degradation in Hunan was analyzed. The soil erosion turns worse, land resource deteriorates seriously, the woodland area reduces, the forest quantity descent; the animal and plant species reduce, some rare species is difficult to see; the natural wetland area decreases, the lake fluid matter pollution aggravates, the TN is more denser; the town air quality in total is stable basically, the river water pollution is widespread; the pollution of noise is in the middle level; the usage of the village chemistry thing rises year by year, the pollution of the environment adds more seriously. The population increases by a big margin, and the economic non-sustainable development is the direct reason. To keep on sustainable development, to resolve the problems brought out by the environment deterioration and unreasonable resource use,in attempt to realize the sustainable development of resources and eco-society.
