7、Conclusion and recommendations

　　In this study, the paper focused on the impact of acid rain on the ecological environment in southern China, firstly using questionnaire surveys to collect data, and found that water and soil are more susceptible to acid rain, and are more likely to harm animals, plants and humans again. Then combined with literature and complex network analysis data, the following conclusions can be drawn: water resources and land resources are important nodes of the entire network of objects affected by acid rain, which is not only easy to be affected but also easy to affect other objects. Therefore, it is necessary to focus on the prevention and control of these two parts of resource pollution. Biological resources are the end nodes of the entire acid rain affected objects. Other words in addition to the direct harm of acid rain, they are more likely to be affected by other objects, so it is necessary to focus on protecting this part of the resources.
　　Based on the above analysis and conclusions, the following suggestions are put forward to improve the impact of acid rain on the ecological environment in southern China:
　　(1)Prevention and control from the source. Develop new energy sources, give priority to the use of low-sulfur fuels and reduce sulfur-containing flue gas emissions.
　　(2)Prevention and control from key nodes. Pay attention to the monitoring and treatment of acidification of water bodies and soil, and appropriately apply quicklime or use other methods to purify water and soil.
　　(3)Prevention and control from the end. Measures to prevent acid rain and direct harm to organisms from contaminated water and soil, such as physical measures such as shielding
