项目摘要

From the viewpoint of sustainable agriculture in sloping farmlands, we analyzed soil erosion conditions affected by the furrowing practices, the arrangement of roads and waterways and farmars' conservation practices. Selecting the test area composed of reclaimed upland fields which had been cropped with a Japanese radish in wide area by monoculture, we read the land use forms and the direction of ridges and furrows on air photos by radio controlled airplane and surveyed the actual furrowing practices and soil erosion patterns to make the sediment source clear, and sent out a questionaire to farmers on their conservation practices. The results obtained were as follows.1. Analysing the geomorphic features of furrowing practices showed that furrows tended to be formed in a more gentle direction along the field boundary and caused soil erosion at the furrow ends.2. Bare fields without furrows had yielded much more sediment than with furrows.3. Effective soil conservation practices need a suitable field arrangement and a grass waterway along the field border to recompense for many farmers' efforts to conserve.4. Farmers had partly paid attension to cropping workability and draining systems without injury by continuous cropping to bring soil erosion.5. Though a rotational cropping system was essential to soil conservation, vergin lands were required for the profitable operate of a small farmer.6. Effective infrastructures which improve cropping workability and drainage systems and the conservation practices are combined to conduct the sustainable agriculture.

从坡耕地可持续农业的角度，分析了坡耕地耕作方式、道路和水路布置方式以及农民保护措施对坡耕地土壤侵蚀状况的影响。选取大面积单一栽培萝卜的复垦旱田组成的试验区，利用遥控飞机对航拍照片进行土地利用形态和垄沟方向的判读，调查实际犁沟方式和土壤侵蚀模式，明确泥沙来源，并向农户发放养护措施问卷。所得结果如下：1。对犁沟活动的地貌特征分析表明，犁沟沿田界向平缓方向形成，造成犁沟末端的土壤侵蚀。没有犁沟的光秃秃的田地比有犁沟的田地产生更多的泥沙。有效的土壤保持措施需要适当的农田安排和沿着农田边界的草地水道，以补偿许多农民的保护努力。农民在一定程度上重视耕作的可操作性和排水系统，而不是连作带来的土壤侵蚀。5 .虽然轮作制度对保持土壤至关重要，但小农户的盈利经营需要处女地。有效的基础设施，提高种植的可操作性和排水系统和保护措施相结合，以实现可持续农业。
