Model Design for Planning the Construction of Protected Areas and Evaluating Their Impact on the Environment
摘要
This paper studies the construction of the Seyhanba Ecological Reserve and the evaluation of its environmental impact. Through the analysis of relevant indicators, the urban planning of the proposed ecological reserve is made and the positive impact of the construction of the reserve on the urban and national environment is evaluated in a reasonable manner. In this paper, we firstly analyzed the data indicators related to Seyhanba and converted the cause-effect relationship among the indicators to determine the forest stock, water content, urban air quality standard days and urban PM2.5 concentration as the characteristic indicators of forest cover area, and constructed a multiple regression evaluation model. Then the entropy weighting method, coefficient of variation method and hierarchical analysis method were used to assign weights to the four characteristic indicators, and then the comprehensive weights were determined by the game theory comprehensive weighting method, which were 0.0429, 0.22, 0.308 and 0.429, respectively. finally the model was solved, and the corresponding coefficients of the four characteristics were 0.105, 0.281, 0.115 and -2.03, respectively. Then the model was extended to Beijing, and the extreme high temperature, average low temperature, average air quality index and the percentage of severe weather were determined as the characteristic indicators of forest cover area, and the combined weights were solved using the same model, which were 0.0916, 0.106, 0.479 and 0.323, respectively. finally the model was solved and the corresponding coefficients of the four characteristics were -0.271, -0.292, 0.595 and -0.196.
