摘要

利用多源遥感数据驱动SRM 模型模拟雅鲁藏布江4个不同水文站控制流域的融雪过程,分析流域特征(面 积、地形地貌因子、植被类型)、模型输入变量(气温、降水、积雪覆盖率)对遥感驱动SRM 模型模拟精度的影响.研究表 明:遥感驱动的SRM 模型在雅鲁藏布江研究区域模拟精度较高,NSE系数达到0.83以上;但其精度受流域面积大小的 影响,具有尺度阈,在一定面积尺度上模拟精度最大,流域地形越复杂,其模拟效果越差;植被覆盖类型影响融雪径流过 程的模拟,进而影响模拟结果;模型3个主要输入变量气温、降水、积雪覆盖率对遥感驱动的SRM 模型的模拟精度同样 有很大程度的影响.研究结果对资料匮乏的高海拔地区水资源利用具有重要意义,同时可为遥感驱动的SRM 模型的推 广应用提供有效支撑.

Abstract

Jinji groundwater sources field in Wuzhong City was selected to study ammonia nitrogen distribution and influencing factors. The hydrogeological conditions of groundwater sources were analyzed. Water samples were collected from 16 groundwater wells in the watersource protection areas, concentration of ammonia nitrogen in the groundwater samples was analyzed. It was found that ammonia concentration in groundwater was 0.025~0.447mg·L-1; ammonia nitrogen was the major potential contaminant in this area. Ammonia concentrations of the groundwater samples were used to construct the spatial distribution of ammonia contamination. Properties of the vadose zone and aquifer were examined; the correlation of groundwater pH, organic matter and ORP with ammonia distribution was analyzed. The present work could provide some scientific basis for the prevention of water sources contamination by ammonia nitrogen, could also contribute to the scientific management of regional water sources and pollution control.
