内容記述 造成農地からの赤土流出の要因は種々ある。本研究は造成完了後の畑地の土砂流亡, 圃場面侵食, 土砂流出の要因解析, 砂防施設の機能等耕地組織と防災施設のあり方を検討したもので, その概要はつぎのとおりである。1.土砂流亡調査において, 濁度は植生圃場やマルチング圃場は無視できる程少ないが, 裸地圃場からの流出は大型沈砂池を通過した流出水でも濁度は高く観測された。2.圃場面侵食調査においては侵食を生ずる圃場面傾斜角度と斜面長の関係はつぎの一次式で表わされる。U=14.69-0.612θここにU : 限界斜面長(m)θ : 傾斜角(度)Uとθの相関関係は0.57で余り高くない。畑面の起状の状態や表土層の物理性が大きく与かっているからである3.パインアップルは植付後約1年間, サトウキビは半年間受食性作物の形態をとるがその後は植生被覆や根による土壌保定効果が現われ, 耐食性の形態をとる。4.大規模な農地造成の際の土砂流出抑止対策としては流出水の一時貯留を図り, 浮遊土砂の河川への直接流出をさけるようにする。5.砂防施設の堆砂機能に関してはTable.3の示すとおりであり流量の如何に関わらず, 水路型の方が高い。
