摘要
将整个太湖流域(江苏)分为49个生态区,从高到低划分为Ⅰ级~Ⅳ级4个等级,综合评价太湖流域(江苏)生态功能。结果表明太湖流域(江苏)生态功能状态处于一般水平,生态Ⅰ级区主要位于溧阳和宜兴的南部山区以及洮湖、阳澄湖和太湖东部湖区,这些区域河流与湖泊生态功能状态多为良好,生态Ⅳ级区主要分布在镇江北部,常州市区,无锡及其辖属江阴的城区,苏州及其辖属县级市的城区,这些区域河流与湖泊生态功能状态多为一般和极差。
The 49 regions of Lake Taihu Basin(Jiangsu)were divided into four grade levels(Ⅰ~Ⅳ)to evaluate their ecological functions.The results show that the overall ecological function of the watershed ecosystem in Taihu Lake Basin(Jiangsu)is in the normal level.TheⅠ-grade ecological area is mainly located in the southern mountainous areas of Liyang and Yixing,as well as Taohu Lake,Yangcheng Lake and eastern Lake areas of Taihu Lake.Most of the rivers and lakes in these areas are in good ecological function.TheⅣ-grade ecological area is mainly distributed in the north of Zhenjiang,Changzhou,Wuxi and Jiangyin,Suzhou and its urban areas under the jurisdiction of county-level cities,the ecological function of rivers and lakes in these areas are generally and extremely poor.
