【摘要】：由于索道建设是在风景区等有旅游开发价值的区域进行建设和运营。因此,对于索道建设带来的生态环境破坏一直是学术关注的重点。一般认为,索道建设的主要环境影响是施工期的生态环境破坏及其带来的生物多样性、水土流失、景观等影响。本论文以对大理苍山大索道建设为例,对施工过程生态环境进行跟踪调查,对建设过程中生态完整性了分析和研究,分析了施工期生态保护措施的有效性。通过对施工过程生态破坏因素研究和措施的有效性研究,为今后索道建设提供实际经验。论文研究表明,大理苍山大索工程建设会对生态完整性造成一定的影响,但建设前后生态系统的类型完整,生态景观结构能保持完整和稳定,生物多样性能程度不变,生物生产力的持续性和稳定性变化不大,所以工程建设后能维持区域生态的完整性。大理苍山大索道建设工程建设扰动原地貌、损坏、占压的土地面积为7.67hm2；损坏水土保持设施面积为6.52hm2；预测时段内可能产生的水土流失总量2164.29t；可能新增的水土流失量为1953.261t。工程产生水土流失的重点部位为索道站场景区和各场地的临时堆场,重点时段为施工期。主要防治措施有索道站场地设置挡土墙、截排水沟及场地绿化;索道站场景区、索道塔基区、供电线路区、材料中转场地区、施工临时道路区在施工过程中采取临时挡护措施和对对施工迹地进行土地整和恢复植被。实施水土保持措施后,扰动土地整治率98.89%,水土流失总治理度98.13%,土壤流失控制比1.03,拦渣率98.84%,林草植被恢复率99.26%,林草覆盖率82.29%。综上所述,只要项目合理选址,施工过程落实各项环保措施,索道建设对生态的破坏较小,不会影响生态的完整性。
[Abstract]:Because the cableway construction is in the scenic spot and so on has the tourism development value area to carry on the construction and the operation.Therefore, the ecological environment damage caused by cableway construction has always been the focus of academic attention.It is generally believed that the main environmental impacts of cableway construction are ecological environmental damage and its effects on biodiversity, soil and water loss, landscape and so on.Taking the construction of Cangshan cableway in Dali as an example, the ecological environment of the construction process is investigated, the ecological integrity of the construction process is analyzed and studied, and the effectiveness of the ecological protection measures during the construction period is analyzed.Through the study of ecological damage factors and the effectiveness of measures during construction, practical experience is provided for the construction of cableway in the future.The research shows that the construction of Dali Cangshan large cable project will have a certain impact on the ecological integrity, but before and after the construction of the ecosystem type integrity, ecological landscape structure can maintain integrity and stability, the degree of biodiversity can not change.The sustainability and stability of biological productivity change little, so the regional ecological integrity can be maintained after construction.In the construction of the Cangshan large cableway in Dali, the original landforms are disturbed, the damaged land area is 7.67hm2, the damaged soil and water conservation facility area is 6.52hm2.The total amount of soil and water loss that may be generated during the forecast period is 2164.29t, and the possible new soil erosion amount is 1953.261t.The key site of soil and water loss is the scenic spot of ropeway station and the temporary yard of each site, and the key period is the construction period.The main prevention measures include the installation of retaining wall, drainage ditch and site greening at the ropeway station, the scenic spot of the ropeway station, the ropeway tower base area, the power supply line area, the material transfer site area,In the construction of temporary road area, temporary protection measures and land consolidation and vegetation restoration are adopted during construction.After the implementation of soil and water conservation measures, the disturbance land remediation rate was 98.89, the total soil erosion control degree was 98.13, the soil loss control ratio was 1.03, the slag retention rate was 98.84, the forest and grass vegetation restoration rate was 99.26 and the forest and grass coverage rate was 82.29.To sum up, as long as the project location is reasonable and the environmental protection measures are carried out during the construction process, the construction of cableway will cause less damage to the ecology and will not affect the ecological integrity.
