本文描述了自然力作用、农业土地利用及采伐原始森林对土壤的影响.所有这些都是所罗门群岛土壤退化的原因之一.为确定和保护容易侵蚀的地区,并帮助其建立允许的土地利用方式必须把流域容量规划与土地的适应性评价结合起来,还必须有实施这些规划的能力,如果是小型农场分散的土地利用方式会加速土壤的退化.本文介绍了按照传统习惯在陡坡地上进行试验研究的计划.这一计划将水土保持策略与耕作制度结合在一起.在采伐迹地上使用重型拖车和掠夺式采伐技术,引起了表层土壤的板结和流失.据调查,严重的土地板结已影响了15～30%的士地.另据生长试验表明,这些土地的生产力已经降低.而有关土壤改良、酸性土壤的治理以及对以往陡坡地的治理资料非常有限.对现有资源的研究,建议有关国际组织分工负责,集中致力于加速重点课题的研究.
This paper describes the effects of natural forces, agricultural land use and the effects of logging of virgin forests on soils, all of which contribute to the soil degradation in the Solomon Islands. To identify and protect areas that are prone to erosion and to help them establish permissible land-use patterns, The combination of watershed capacity planning and land suitability assessment must also have the capacity to implement these plans and, in the case of small-scale farmland dispersal of land-use options, to accelerate soil degradation.This paper presents a pilot study on steep slopes according to traditional practices Plan that combines soil and water conservation strategies with tillage systems and the use of heavy-duty trailers and predatory harvesting techniques at deforested sites that cause surface soil compaction and loss.According to the survey, severe land consolidation has affected 15 ~ 30% of the land .According to growth tests show that the productivity of these land has been reduced.And the soil improvement, acid soil management and the management of steep slopes in the past very limited information on the existing resources, it is recommended that the relevant international organizations Responsible for the division of labor, focused on accelerating the study of key issues.
