辽宁滨海公路跨越锦州市开发区和凌海市,为辽宁省水土流失重点治理区、重点监督区,侵蚀类型为水力侵蚀,本区属北方土石山区,容许土壤流失量为200 t/(km2.a)。水土流失防治标准确定为Ⅱ级。针对建设活动引起水土流失的特点及其危害程度,将工程措施、植物措施、临时措施有机结合起来,并把主体工程中具有水土保持功能的措施纳入水土流失防治体系,科学配置,形成完整的防治体系。通过实施本方案水土流失总治理度达96.9%,林草植被恢复率达97.5%,拦渣率达98%以上,林草覆盖率达27.7%。通过本方案的实施,因工程建设而造成的水土流失得到有效控制,生态环境得以恢复。 Liaoning Coastal Highway crosses over Jinzhou Development Zone and Linghai City. It is a key control area and a key supervision area for water and soil loss in Liaoning Province. The erosion type is hydraulic erosion. The area belongs to the northern rock and mountainous area, and the soil loss amount is 200 t / (km2). a). Soil and water loss prevention and control standards identified as Ⅱ level. In view of the characteristics of soil and water loss caused by construction activities and the degree of harm to them, the project measures, plant measures and temporary measures are organically integrated and the measures of water and soil conservation in the main project are incorporated into the system of soil and water loss prevention and control and scientifically allocated to form a complete prevention and control system. Through the implementation of the program total soil and water loss control of 96.9%, forest grass vegetation recovery rate of 97.5%, blocking rate of 98% or more, grass coverage rate of 27.7%. Through the implementation of this program, the soil and water loss caused by the construction of the project is effectively controlled and the ecological environment is restored.
