SP45與SP60多功能被覆資材之抗沖蝕能力試驗

市面上常見水土保持的抗沖蝕網毯頗多，但為了達到抗沖蝕的效果其厚度增加及加勁材補強補均會影響植生的初期萌芽與後續生長。由國外引進的SP45與SP60兩型多功能植生披覆資材，就是希望能同時滿足初期抗沖蝕與不影響植物生長的目標，而進行相關的檢測比較。結果顯示資材在植生復育前期可以有效的降低逕流與沖蝕量，而到植生復育中、後期雖然逕流量會恢復，但是卻因為有植生的保護，使得沖蝕量沒有因而增加；其中SP60比SP45有較佳的吸水性及保水能力，故減少逕流量的效果明顯。又SP45與SP60兩型鋪設後，比較植生覆蓋率均較裸露的土壤試體為佳，顯示其能有效保護地表、恢復植生與防止沖蝕的功能。

There are many erosion resistant rugs of soil and water conservation on the market, but in order to achieve the effect of erosion resistance, the increased thickness and the reinforcement of the stiffener will affect the initial germination and subsequent growth of the plant. The SP45 and SP60 two-type multifunctional vegetative mulch materials imported from abroad are expected to meet the objectives of initial erosion resistance and non-influence of plant growth, and related detection and comparison. The results show that the materials can effectively reduce the runoff and erosion in the early stage of planting and breeding, and the runoff will recover in the middle and late stages of planting and breeding, but the erosion is not increased because of the protection of vegetative. Among them, SP60 has better water absorption and water retention capacity than SP45, so the effect of reducing runoff is obvious. After SP45 and SP60 were laid, the ratio of vegetation coverage was better than that of bare soil samples. It shows its ability to effectively protect the surface, restore vegetation and prevent erosion.
