在基于统计学理论的水质遥感反演研究基础上,利用Landsat-TM遥感影像数据,结合水质反演的原理,选取典型丘陵区———永川区主要水库水体水质参数(叶绿素a、悬浮物、透明度、水温和氨氮)为研究对象,建立遥感信息同实测数据间的响应关系,得出具有区域代表性的反演模型,初步形成了一套基于遥感的分布式水质定量测算研究方法,分析结果得出水体中叶绿素a、水温和氨氮精度较高,悬浮物、透明度精度较低。 更多还原

【Abstract】 Based on the statistics theory and the principle of remote sensing retrieval technology in water quality,using Landsat-TM remote sensing image data,the water quality parameters(chlorophyll a,suspended substance,transparency,water temperature and ammonia nitrogen)in Yongchuan District which is a typical hills region were selected as study object,the corresponding relationship between remote sensing and measured data was established,the regional representative model was obtained,a set of distribut... 更多还原
