山东省湖库水质地域差异及因子分析

Regional Differences of Water Quality of Lakes and Reservoirs in Shandong Province and Analysis

综述山东省湖库的基本概况,依据湖库水质参数与营养度指数的关系,在湖库分区的基础上,对4个湖库区的总氮、总磷、叶绿素a和透明度等基本水质参数作区域差异分析,经ArcGIS软件分析计算表明:受地形、降水和人为因素的影响,山地丘陵或乡村地区的湖库水质明显好于平原或城市湖库,工业区和人口聚集地湖库污染状况相比更为严重。

The basic overview of lakes and reservoirs in Shandong is summarized,and then,according to the relationship between water quality parameters and nutrition index,as well as on the basis of the partition of lakes and reservoirs,the regional differences of water quality parameters,including total nitrogen,total phosphorus,chlorophyll A and transparency,are analyzed.The results from ArcGIS analysis show that:under the influence of topography,precipitation and human factors,the water quality of lakes and reservoirs in the mountainous and hilly or rural areas is significantly better than that in plain or urban areas;and the water pollution is more serious in industrial areas and populated areas.
