铁路客运专线建设期生态影响评价研究

根据铁路客运专线建设期对生态环境影响的特点,提出生态影响评价内容,采用目标分解法、调查研究法和压力-状态-响应模式相结合的方法构建生态影响评价指标体系,共包括生态影响、环境影响、景观影响和社会经济及资源利用影响4大类19个基础指标。用改进的层次分析法确定各指标的权重,用线性加权的方法确定综合评价结果,对客运专线建设进行生态影响综合评价。以合福客运专线福建段为例进行评价,结果表明：工程建设期会对环境产生较弱程度的影响。

Ecological Impact Assessment Study of Passage Line Building

Based on characteristics of ecological impact in passage lines＇ building,the content of ecological impact assessment is proposed,index system is established by using target decomposition,investigation and pressure-state-response model.Four categories are included in the system like ecological impact,environmental impact,landscape impact,social economy and resource utilization impact.Nineteen fundamental indexes are contained in these four categories.Improved analytic hierarchy process is adopted to confirm the weight of each indicator.Linear weighted sum method is applied to confirm comprehensive evaluation result.The ecological impact of passage line is assessed synthetically.Taking the passage line from Hefei to Fuzhou as an example,the results show that the construction of the passage line brings about a relatively smaller influence on environment.
