摘要
风力侵蚀普查是第一次全国水利普查水土保持情况普查的重要内容之一。抽样调查方法是风力侵蚀普查的重要方法。在介绍我国风力侵蚀野外调查单元布设、基础数据收集的基础上,详细介绍风力侵蚀模型、侵蚀因子计算方法,并结合实际调查情况,对包括资料准备、野外调查、汇总上报和成果评价等普查过程的各个阶段及其质量控制措施进行详细总结。普查技术方法的正确把握对于保证普查结果的可靠性、科学性和权威性具有重要意义,普查结果可为国家水土保持规划与生态环境建设提供基础数据。
Wind erosion survey is an important part of the first national water resource survey. The sampling investigation is the main method of wind erosion survey. Based on field sampling units layout and basic data collection, the author introduced wind erosion model and each erosion factor calculation methods. In addition, combined with survey, basic material collection, field investigation, gather and report, and results evaluation of each stage and those quality controls were summarized in detail. Correctly understanding the census method was of great significance for assurance the reliability, scientificalness and authority of the census results. The result provided basic data for national soil and water conservation planning and ecological environment construction.
