中国（国际）水务高峰论坛在线——2014（第二届）中国水利信息化与数字水利技术论坛（论文集） 基于高分一号数据的饮用水水源地污染源遥感分析 ——以石头口门水库为例 廖晓玉，刘媛媛 摘要：饮用水水源地是城镇用水的重要蓄存地，做好饮用水水源地污染调查是保障饮用水水 源安全的重要前提和基础。遥感技术弥补了传统调查手段的不足，能大范围、快速、客观地 获取地表信息。本文选择石头口门水库水源地作为研究区域，应用高空间分辨率卫星“高分 一号”数据，对其二级保护区范围内土地利用/土地覆盖现状进行调查，分析水库水源地非 点源污染分布及特点。结果表明，石头口门水库水源地二级保护区内农业用地、居民区、采 矿用地、养殖用地等非点源污染普遍存在，其中，农业用地占总面积的比例最大，说明该区 人类农业活动强度较高。基于高分一号数据的水库水源地遥感分析结果能为石头口门水库水 源地现场执法管理及风险预警研究提供技术支持，为水源地的进一步规划和治理提供科学依 据。 关键词：水源地； 高分一号；遥感；土地利用/土地覆盖；非点源污染 Analysis on the Pollution Sources of Drinking Water Source Using High Spatial Resolution Satellite Data -- A case study of the Shitoukoumen Reservoir Liao Xiaoyu, Liu Yuanyuan, (Bureau of Hydrology (Information Center), Songliao Water Resources Commission, Ministry of Water Resources, Changchun 130021, China) Abstract: Drinking water source is an important conservative place of urban domestic water. A well pollution source investigation is a significant prerequisite and foundation to protect the safety of drinking water source. Remote sensing technology can remedy the limitations of traditional means; can obtain large-scale, rapid and objective information from surface. Using high spatial resolution data--the First Satellite of High Resolution, Land use/land cover in the secondary reserve of Drinking Water Source of Shitoukoumen Reservoir was investigated, the distributions and characteristics of non-point source pollution were analyzed. The results show that the farmlands, residential areas, mining lands and fishery lands were widespread in the secondary reserve, and the proportion of the total area of the farmlands is the largest. It explains high strength human agricultural activities in this region. The results of this study provide technical support for the law enforcement management
