中国水土保持监测站点的建立与作用

Establishment and roles of soil and water conservation monitoring stations in China

  • 摘要: 水土流失是全球性的农业和环境问题,是引起土地退化的主要驱动因素。开展水土流失动态监测是合理利用水土资源和科学防治水土流失的前提。水土保持监测站点是水土流失动态监测工作的基础单元,水土保持监测网络的持续强化建设,可定量明确区域水土流失状况、分布及变化趋势,这对科学制定防治决策具有重要作用。本文概要阐述了世界水土流失监测发展历程,评述了中国水土流失动态监测现状,梳理了中国水土保持监测网点建设经验,总结了监测站点在水土流失动态监测中的作用,提出了水土流失监测存在的问题,以期为水土流失综合防治以及理论研究提供支撑。

     

    Abstract: Soil erosion is an agricultural and environmental problem globally and a primary driving factor causing land degradation. Conducting dynamic monitoring of soil and water loss is a prerequisite for rational utilization of water and soil resources as well as scientific prevention and control of soil and water loss. The monitoring station for soil and water conservation is the basic unit for dynamic monitoring work of soil and water loss. The continuous strengthening for the construction of soil and water conservation monitoring network can quantitatively understand the status, distribution, and change trends of regional soil erosion, which is of crucial importance in developing scientific decisions for prevention and control. This paper elaborates the development history of global soil and water monitoring briefly, reviews the current situation of dynamic monitoring of soil and water loss in China, sorts out the experience in the construction of China's soil and water conservation monitoring network, summarizes the role of monitoring stations in the dynamic monitoring of soil and water loss, and points out the existing problems in soil and water loss monitoring. This study could provide support for the integrated prevention and control of soil erosion and theoretical research.
