4、Methodology

　　3.1.Questionnaire
　　This study adopted the research method of questionnaire survey. First of all, the article used Wikipedia to find the definition and classification of the ecological environment, so as to classify the affected objects of acid rain and form a diagram of the influencing factors. Secondly, the specific impact of acid rain on the ecological environment in southern China was investigated by issuing questionnaires, and finally the correlation between different affected objects of acid rain supplementation was analyzed in combination with literature. The questionnaire was divided into two types of questions, one was the respondent\'s basic situation survey , and the other asked participants to choose the target of acid rain as they thought was appropriate.
　　The article defined ecological resources as composite ecosystems associated with sustainable social and economic development, and the article argued that acid rain would not only have a direct impact on affected objects, but also have an impact on other affected objects, these objects make up the entire ecosystem.The relationship between objects is as follows:
　　Because the research questions of the research report have certain specialization and geographical scope restrictions, the research subjects need to have a environmental professional background, knowledge about the environment, and some understanding of southern China. So that the results of the questionnaire could be reliable. Therefore, the article chose to distribute questionnaires to students and teachers of environment-related majors who have some knowledge of southern China to collect reliable data, and the number of questionnaires distributed was 200.
　　3.2.The Complex Network
　　For the data collected through the questionnaire, this paper adopted the complex network analysis method to analyze and organize the data. This paper regarded the impact of acid rain on the ecological environment system as a network, all the influencing factors as network nodes, and the interaction between the influencing factors as the edge of the network, through this complex network could help us analyze the key impact objects and key impact paths of acid rain on the ecological environment, help us further analyze the specific prevention and control programs for acid rain.
