不同尺度作用区内景观格局指数对浑河水质的影响

Influence of Landscape Pattern Index of Different Scales Active Region on Water Quality of Hun River

本文将浑河流域作为研究对象,基于数字高程数据和遥感影像,结合水质监测结果,利用景观格局指数对流域景观分布特征进行分析,建立5种尺度缓冲区对流域水质与土地利用方式间的关系进行研究,并对水质指标与景观指数间的相关性进行分析,该研究可为生态建设以及制定水环境污染防治方案提供科学依据。

Based on the digital elevation data and remote sensing images,combined with the results of water quality monitoring,this paper analyzes the landscape distribution characteristics of the river basin by using the landscape pattern index,and establishes the five scale buffers to analyze the relationship between water quality and land use. The relationship between water quality index and landscape index is analyzed,which provides scientific basis for ecological construction and water pollution prevention and control program.
