| 摘 要： | 经对庆元县突发性山地水土灾害与土地利用类型作相关研究后发现,林业用地灾害发生绝对量最大,尤其是杉、松用材林,而天然常绿阔叶林和材用毛竹林几乎没有发生.灾害发生密度以耕地最高,尤其是山坡旱地,居二级土地利用类型之首,其次是望天田.因此,防治山地灾害必须考虑梯地、梯田的退耕还林.在南方山区,封山育林、保护自然植被,是防止山地灾害的有效措施,而发展材用毛竹林是山区生态经济开发的有效途径.

| Abstract: | In this paper the relationship between unanticipated water and soil disaster and landuse in Qingyuan county was studied. The results showed that the amount of disasters on woodland was the largest, especially on pine and fir woodland. However, there was no disasters happened on natural evergreen broad leaved forest and timber available phyllostachys pubescens forest. It was farmland that had the highest disaster density, and the sloping dryland ranked the first of the secondary landuse types, followed by irrigated rice paddy. So, to prevent mountainous disasters, reforesting of the dry sloping cultivated must been adapted. In southern mountain areas, closing hillsides to facilitate afforestation was the effective measure to avoid mountainous disasters, and growing timber available phyllostachys pubescens forest was an effective approach to develop ecological economy. |
