辽宁省本溪市自1990年以来,充分发挥生物措施固岸护堤、消减水势的作用,每年营造的生物堤防均超过百公里,取得了较好的效果。 本溪市根据山区河道的特点及河滩地砾石较多,土层浅薄湿润,较适合杨、柳、枫杨及水曲柳等树种的生长,采取了成片栽植,株行距为15m×15m,造林技术措施和标准按有关林木育苗技术规程执行。造林前一年整地,翌年春造林,按设计密度定点,在实施生物工程措施前确定整治标准和标准线。布置
Since 1990, Benxi City, Liaoning Province, has given full play to the effect of biological measures for embankment protection and reduction of water potential, and each year more than 100 kilometers of bio-embankments have been built with good results. Benxi City, according to the characteristics of mountainous rivers and river beach gravel, shallow soil moist, more suitable for Yang, Liu, Feng Yang and Ash and other tree species growth, taken into pieces, spacing 15m × 15m, afforestation technical measures And standards according to the relevant forest seedling technical regulations. One year before afforestation and soil preparation, the next spring planting, according to the design density of fixed point, in the implementation of bio-engineering measures to establish remediation standards and standards.
