摘要
采用模糊综合评价法及基于ArcGIS空间插值分析法评价赛里木湖水质并对其空间分布规律进行研究。研究结果表明,影响赛里木湖水质的主要因素为有机类,营养盐次之,总体水质达Ⅲ类标准。空间分布呈东部、西部浓度高于中部的特点,形成原因主要是水生植物和栖息动物等死亡腐烂遗留的物质较多,同时入湖河流的水质也是形成该规律的主要原因。
Based on ArcGIS, the fuzzy comprehensive evaluation and space difference analysis method is used to assess water quality and study spatiotemporal distribution features of Sayram Lake. The results show that the main factor in influencing water quality is organic nutrient ranking the second place, water standard is Ⅲ. Spatiotemporal distribution tending to eastern and western is higher than the middle part. The main forming reason is dead and decaying, aquatic plants, animals, leaving more pollution. Meanwhile, the water quality within the inflow lake is also another main reason.
