| 中文摘要: |
| 林地水源污染关系到整个自然保护区内生物的生存与发展，为保护水源水质开展了水源污染修复及防治策略研究。以某自然保护区内的一处水源地为例，采集试验所需的原水，在选取试验试剂和设备的基础上，确定4项水质分析项目和对应的检测方法。通过壳聚糖微球+活性渗滤反应墙、原位投菌技术来修复水源，通过人工湿地和人工增氧来实现污染防治。结果表明，修复策略实施后，各项水质指标表现越来越好，林地水源中浮游生物数量和叶绿素a含量逐渐上升，重金属综合污染指数和高锰酸盐指数逐渐下降，修复策略起到了应有的净化效果；防治策略实施后，前1~3 d内4项水质指标的表现仍在继续提升，之后出现小幅度下降并最终维持在一个较为平稳的水平，说明防治策略基本维持住了修复策略的实施效果，起到了应有的防治作用。 |

| Water source pollution of forest land is related to the survival and development of organisms in the whole nature reserve. In order to protect water quality, it is important to study water source pollution remediation and prevention strategies. Taking a water source in a natural reserve as an example, the raw water required for the test was collected, and four water quality analysis items and corresponding detection methods were determined based on the selection of test reagents and equipment. For the raw water, the water source was first repaired by chitosan microspheres+active infiltration reaction wall, and in-situ bacterial injection technology, and then the pollution prevention was realized by artificial wetlands and artificial oxygen enrichment. The results showed that after the implementation of the remediation strategy, the performance of various water quality indicators became better, the number of plankton and chlorophyll a content in the forest water source gradually increased, the comprehensive pollution index of heavy metals and permanganate index gradually decreased, and the remediation strategy had played a due purification effect; after the implementation of the prevention and control strategy, the performance of the four water quality indicators continued to improve in the first 1-3 days, then decreased slightly and finally maintained at a relatively stable level, indicating that the prevention and control strategy basically maintained the implementation effect of the remediation strategy and played a due role in prevention and control. |
