| 摘 要： | 采用GIS技术和生态环境状况评价技术规范,对白洋淀流域生态环境状况进行了评价。结果表明:白洋淀流域生态环境状况指数为53.03,属“一般”级别,表现为植被覆盖度中等,生物多样性一般,较适合人类生存。流域水网密度指数和环境质量指数低,仅分别为11.18和12.68,是造成流域内生态环境状况指数偏低的主要原因,也是人类生存的制约因子。 |

| Abstract: | The eco-environment of Baiyangdian Lake Watershed was evaluated by using GIS technology.The results show that the exponent of eco-environmental status is 53.05 graded as "general grade".This grade of eco-environmental status has a medium vegetation coverage and biodiversity with suitable environment for human living.The limiting factors for human living in the area are water density and environmental quality,which are lower,11.18 and 12.68,respectively. |
