摘要
台湾泥岩为全省山坡地灾害中最难整治的地区 ,素有台湾坡地之癌的恶地称谓。其特征为干旱时坚硬 ,热胀冷缩易呈片状剥落 ,潮湿时则泥泞滑落 ,以致水土灾害频繁。而在裸露坡面 ,年平均冲刷深度更高达 7.5 cm,犹以东南坡向最严重。在生态方面 ,由于裸露面积迅速扩大、植被纯林化与栖地破坏 ,造成区域生态之失衡 ,生物歧异度遽减及微气候异常等。因此 ,汇整十几年来各方专家学者之经验与成果 ,拟就泥岩地区主要之冲蚀控制、水土保持工程与生态复育、监测方法加以配合 。
Due to the difficult control of soil and water conservation,the mudstone area in the Taiwan has always had a bad name 'cancer of slope land'to represent its poor environmental condition.For the bare slope,the average erosion depth is above 7.5 cm and data show that Southeastern aspect having the higher soil loss (9.5 cm).The ecological system in this area, ecological unbalance occurred in mudstone areas in Taiwan due to the bare area increase,improper land use,and vegetation one type and habitat disturbance.Therefore,considering the ecological management as a whole, some erosion control of vegetation method and engineering methods were taken and ecological evaluated in mudstone area.
