生态监测在铁路建设项目中的应用

Application of Ecological Monitoring in Railway Construction Projects

以常规生态监测结合遥感技术手段,对郑徐客运专线穿越中牟森林公园的生态影响进行监测。结果表明,2016年较2015年,中牟森林公园Simpson植被优势度指数、Shannon-wiener多样性指数等指标均有所增加,森林公园内生态植被均处于自然生长及更新状态;通过遥感监测,2016年较2015年,交通运输用地、草地均有所增加,林地略减,工程扰动面积减少,说明工程对森林公园的影响正在逐步降低,工程所引发的水土流失减少,生态有所恢复和改善。

Using conventional ecological monitoring combined with remote sensing technology,the ecological impact of Zhengzhou-Xuzhou Passenger Dedicated Line crossing Zhongmu Forest Park was monitored.The results showed that Simpson vegetation dominance index and Shannon-wiener diversity index in Zhongmu Forest Park increased in 2016 compared with 2015,and the ecological vegetation in forest park was in the state of natural growth and renewal.According to remote sensing monitoring,in 2016,compared with 2015,transportation land and grassland increased,woodland decreased slightly,and engineering disturbance area decreased,indicating that the impact of the project on forest park is gradually decreasing,soil erosion caused by the project is reduced,and the ecology is restored and improved to some extent.
