人工模拟降雨条件下红壤水土保持效应的研究综述

概括了我国南方红壤土水土流失的现状及危害,提出亟待保护的迫切要求,通过综合分析坡地试验小区的土壤侵蚀模数、产流特征,研究不同植被小区的水土保持效应,并且分析降雨对小区水土流失的影响,以期对红壤土的综合利用提出理论支持。针对我国红壤退化日益严重的问题,在人工模拟降雨条件下,分析红壤水分特征、产汇流过程所做的研究工作,通过研究找到合适植物以改良红壤,使得红壤沙化过程减缓。

Review of Soil and Water Conservation Effect in Red Loam under Rainfall Simulation

The status quo and damage of red loam erosion in southern China was introduced, it raises an urgent requirement that the red loam in southern China must be protected. Through analysis on soil erosion modulus and the characteristics of runoff yield, soil and water conservation effect in different plantation plot was studied, effects of rainfall on water and soil erosion were analyzed, so as to provide theoretical support for comprehensive utilization of red loam. In view of the increasingly serious problem of red loam, under the system of rainfall simulation, research work of water characteristic and runoff progress was analyzed, so as to find available plants for modifying red loam, and slow done the desertifica- tion process.
