中文摘要: |
以第二松花江子流域为研究区,利用RS 和GIS 技术,基于水利部《河流健康评估指标、标准与方法V1.0》并加以改进,将整个河漫滩纳入河流物理结构健康评价的范围,科学地选取相应评价指标,建立520 个物理结构评价基本单元,形成基于RS 物理结构评价方法。研究结果表明:14 个采样点,基于RS 物理结构评价结果在0.54~0.80 之间,地面实测评价结果在0.55~0.79 之间,两种方法评价结果的数值差异均在0.2 之内,其差异均在一个健康状态等级之内,且与研究区河岸带物理结构健康状态的总体趋势吻合。 |
英文摘要: |
Taking the Second Songhua River sub-basin as a study area, the entire floodplain is included in the scope of the physical structure of the river health assessment by RS and GIS technology, based on the improved "Assessment of River Health Indicators, Criteria and Methods V1.0" of the Ministry of Water Resources. Selecting the appropriate evaluation indicators,an evaluation method based on the physical structure of RS is formed with 520 basic units for physical structure evaluation. It is shown that with 14 sampling points, the evaluation results of the RS physical structure lie between 0.54~0.80, and the evaluation results of on-the-spot investigation lie between 0.55~0.79. The differences between the evaluation results of the two methods are less than 0.2,which are all within the level of a healthy state and coincident with the overall trend of health status of the physical structure in riparian zone of the study area. |
