基于BP神经网络的广汕铁路对广东海丰鸟类省级自然保护区生态影响综合评价

Comprehensive assessment of ecological impact in Guang-shan railway project for Guangdong Haifeng Birds Provincial Nature Reserves based on BP neural network

以广东海丰鸟类省级自然保护区为研究对象,结合广汕铁路建设的影响,从生态影响、环境影响和景观影响3个层次建立了生态环境影响评价指标体系,运用BP神经网络模型对9个指标进行综合评判。结果表明:广汕铁路建设对广东海丰鸟类省级自然保护区的生态影响评价结果为较小影响。评价结果为评判工程建设对保护区的影响提供了科学依据。

Taking Guangdong Haifeng Birds Provincial Nature Reserve as research object,combined with the influence of Guang-shan railway construction,a complete index system of ecological environmental impact assessment was established by selecting 9 indexes from three levels:ecological impact index,environmental impact index and landscape impact index.BP neural network model was used to comprehensively evaluate 9 indexes.The evaluation result showed that,the ecological impact assessment results of Guang-shan railway project on Guangdong Haifeng Birds Provincial Nature Reserve showed a small impact.The evaluation results provide scientific basis for evaluating the impact of engineering construction on the protected area.
