摘要
回顾了国外区域性土壤侵蚀调查的历史,梳理了我国土壤普查、森林资源清查、土地资源调查、污染物普查的周期和方法,在总结我国开展水土保持普查工作的基础上,参考水保专家的问卷调研结果,建议每5年进行一次全国水土保持普查、每年在重点区域进行连续监测,同时在现有调查单元布局的基础上,进一步提高单元密度,建立高分辨率航卫片资料数据库,加强"3S"技术在水保普查中的应用。
The paper reviewed the history of regional soil erosion survey both at home and abroad,refreshed the cycles and methods of soil general survey,forest resources check,land resources survey and pollutant general survey of China and suggested to conduct national general survey of soil and water conservation every 5 years,conduct continuous monitoring in the key areas every year and based on the existing layout of survey unit further increase the density of unit,establish a data bank of satellite images and aerial photograph with high resolution and strengthen the application of'3S'technology to the general survey of soil and water conservation based on the summary of conducted general survey of soil and water conservation of China and referred to the results of questionnaire of experts.
