| 摘 要： | 以大兴安岭砂金开采区内河流域为研究对象,采用1990年和2000年两个时相的ETM遥感数据,提取河流域水质的悬浮泥沙和叶绿素分布及变化情况。研究表明,利用定量遥感模型可有效地揭示研究水域泥沙及叶绿素变化情况。结果表明,大兴安岭砂金开采区流域高等悬浮泥沙含量2000年较1990年增长38.7%,流域悬浮泥沙污染重;极高叶绿素质量浓度分布面积2000年较1990年减少了6.17%,叶绿素对污染不严重。可见遥感技术在矿区水质环境监测的独特优势,有利于提高矿区环境监督的力度,确保矿区资源开采和环境保护相协调。

| Abstract: | The information on distribution and change of suspended sediment and chlorophyll in the water area of the placer gold region in the Great Xing'an Mountains was extracted according to the ETM remote sensing data in 1990 and 2000.Results showed that the model for quantitative remote sensing could effectively reflect the changing situation of suspended sediment and chlorophyll in the water area.The concentration of suspended sediment in the water area of the placer gold region in Great Xing'an Mountains in the... |
