In recent years, the rapid development of coastal areas has polluted the watershed water, affecting the ecological environment of wetland scenic spots. This paper briefly introduced the constructed wetland, a means of watershed water pollution control, and briefly explained its mechanism of water pollution control. Then, an example of Yancheng Coastal Wetland Natural Reserve in Jiangsu Province was analyzed to analyze water quality ecological changes in the basin before and after the construction of constructed wetland. The results showed that the basin of the natural reserve changed from acidic to alkaline, and ammonia nitrogen, total nitrogen, total phosphorus and chemical oxygen demand decreased significantly and maintained at a relatively low level after the constructed wetland controlled the water pollution in the basin; subsurface constructed wetland had a better effect on reducing ammonia nitrogen, total nitrogen and total phosphorus; surface constructed wetland had a better effect on reducing chemical oxygen demand. In conclusion, constructed wetlands as a means of water pollution control in the watershed can effectively improve the water quality ecology of coastal wetland natural reserves.

流域水污染控制对沿海旅游景区的生态影响

近年来,沿海地区的快速发展污染了流域水,影响了湿地风景区的生态环境。本文简要介绍了人工湿地,作为流域水污染控制的一种手段,并简要说明了其控制水污染的机理。然后,以江苏省盐城沿海湿地自然保护区为例,分析了人工湿地建设前后流域水质的生态变化。结果表明,自然保护区流域由酸性变为碱性,人工湿地控制流域水污染后,氨氮,总氮,总磷和化学需氧量显着下降,并保持在较低水平。地下人工湿地对减少氨氮,总氮和总磷的效果更好。表层湿地对减少化学需氧量有更好的效果。综上所述,人工湿地作为流域水污染控制手段可以有效改善沿海湿地自然保护区的水质生态。
