基于地学信息图谱的生态环境质量评价——以黑龙江省绥化市为例

Assessment of Eco-environmental Quality on the Basis of Geo-information Tupu——The Example of Suihua City of Heilongjiang Province

为评价黑龙江省绥化市生态环境质量现状,利用地理信息系统作为数据挖掘手段,以2004年土地利用数据、土壤数据、气象数据等为基础,构建反映区域环境质量状况的图谱信息,来反映绥化市生态环境质量状况。结果表明,绥化市生态环境质量以良好为主,占全区总面积的60.16%,主要分布在西部和中东部地带,环境质量为优的区域面积占11.68%,主要集中在东北,而环境质量为一般的区域占28.16%,主要分布在中北部地区。研究表明信息图谱不但是区域生态环境质量评价的有效手段,还可以反映出区域内部生态环境质量的差异。

To evaluate the eco-environment quality of Suihua,Heilongjiang province,this paper develops Tupu information which can reflect the quality state of regional environment on the basis of GIS technology,the land use data,soil data and weather data of the year 2004.The results show that the quality of Suihua eco-environment is mostly favorable,which accounts for 60.16% of the total area,mainly in western and middle eastern areas.The area with excellent quality of the environment accounts for 11.68%,primarily in the northeast.While the area with ordinary quality accounts for 28.16%,mainly in the central and northern regions.The study proves that the use of information Tupu not only is an effective means of quality assessment of regional eco-environment quality,also can reflect the quality differences of eco-environment in regional interior.
