于1988年1月,在曼谷举行了国际土壤资源保护会议.我们回顾了土壤和适宜土地防蚀进程的特性,受侵蚀影响小的土地仍需要保护.因为刚刚开始的侵蚀往往不被人们注意,然而侵蚀发展速度很快,从而引起生产急剧下降和很多管理问题,经常导致当地产品最终成为沉积物,庄稼因为土壤流失而被破坏.我们已认识到了侵蚀的危害性,并且把它作为资源保护规划过程中的一部分.其余的规划步骤是按照使用顺序进行:考虑到土壤的抗蚀性:对土地评价重点应放在土地使用类型上;保护措施应优先考虑在有高度保护基础的最适宜的土地上及最容易发生土壤流失的土地上(近期、将来);现在需要做的是把危害性降低到可以接受的程度;目前在可利用土地类型或在可选择土地类型上进行土壤改良.我们应把重点放在对适宜土地的限制上,这些限制应在同一时期被控制在同一程度上.土地保护应该被看作是任何地区事业发展的一部分.我们分类的处理规划过程,至少能帮助我们得到部分结论.我们对计划步骤可进行定量分析,但是规划通常是从当地或从外面专家所掌握的知识基础上去定性分析.这些步骤导致土地资源保护规划过程最终成为自动化.具体内容主要为:1.雨水侵蚀过程和土地生产率;2.为土地保护规划提供侵蚀危害信息;3.结论这三部分.
The International Conference on Soil Conservation was held in Bangkok in January 1988. We reviewed the characteristics of soils and suitable land erosion prevention processes and the land that is less affected by erosion still needs protection because the initial erosion is often unnoticed, However, the rapid development of erosion has led to a sharp decline in production and many management problems that often result in the local products eventually becoming sediments and crops being destroyed due to soil erosion. We have recognized the dangers of erosion and used it as a resource conservation plan The remaining planning steps are performed in the order of use: Considering soil erosion resistance: land evaluation should focus on the type of land use; protection measures should give priority to the most suitable land with a high degree of protection (In the near future, in the future) where the loss of soil is most likely to occur; what is needed is to reduce the level of harm to an acceptable level; currently there is available land improvement or soil improvement on alternative land types. Focusing on the restrictions on suitable land, these restrictions should be controlled to the same extent over the same period. Ground protection should be seen as part of the career development in any region. Our classification of the process of planning at least helps to get some of the conclusions. We can quantify the planning steps, but the planning is usually from a local or outside expert Of the knowledge-based qualitative analysis of these steps lead to land resource conservation planning process eventually become automated.The specific content mainly as follows: 1 rainwater erosion process and land productivity; 2 for the protection of land protection programs provide information on erosion hazards; 3 Conclusion of these three parts .
