壤中流作为土壤内水分循环的一个重要环节,对整个流域径流的发生、土壤养分运移、灾害预报以及流域水文循环的计算都具有相当重要的作用。为了更加深入的认识壤中流,提高水资源利用效率和流域生态安全水平,本文对前人的研究成果进行了简要概述,在此基础上总结了壤中流的三种效应影响:即水文效应、土壤养分运移效应和诱发地质灾害效应,并概括了壤中流调控的主要措施。总结出几点关于壤中流研究开展的建议:(1)在黄土高原地区开展有关壤中流的研究;(2)提高模型模拟精度和适用范围,并实现壤中流动态监测;(3)开展土壤养分及污染物在壤中流中运移机理研究;(4)开展壤中流诱发地质灾害的机理研究;(5)加强壤中流调控体系与调控措施研究。
Soil mid-stream as an important part of soil water cycle plays an important role in runoff occurrence, soil nutrient transport, disaster prediction and hydrological cycle calculation in the whole basin. In order to further understand the midsize flow and improve the utilization efficiency of water resources and the level of eco-safety in the basin, this paper briefly summarizes the research results of predecessors, and on this basis summarizes three effects of mid-flow: hydrological effects, soil Nutrient migration and induced geological disasters, and summarized the main measures of soil flow regulation. Summarize some suggestions about the study of middle-stream flow: (1) research on middle-stream flow in the Loess Plateau; (2) improve simulation accuracy and application range of the model and achieve flow-in-soil monitoring; (3) And the transport mechanism of pollutants in the mid-stream. (4) To study the mechanism of the mid-stream-induced geological disasters. (5) To strengthen the research on the mid-flow regulation system and regulation measures.
