摘要
本文研究了南方红壤侵蚀区水土保持植物群落结构对土壤理化性状的影响,结果表明水土保持复合植物群落结构不仅能够有效地减少土壤流失量,而且使土壤理化性状得以改善。水土保持复合植物群落结构可增强土壤保水保土能力,稳定土壤水分和温度,改善土壤通透性,提高土壤pH值及土壤肥力水平,达到增肥、改土、稳产目的,从而促进农业生态的良性循环。同时,笔者建议在南方红壤侵蚀区种植果树的生产实践中采用水土保持复合植物群落结构。
The effects of soil and water conservation plant com munity structure on soil properties in eroded red soil region of south china wer e studied.Results showed that the plant community structure can not only reduce soil erosion,but also improve the physical and chemical properties of soil.It w a s found that compound plant can strengthen the ability of keeping water and soil ,stabilize soil moisture and temperature,and improve soil perviousness,increase the pH value and soil fertility,so to attain the purpose of fertilizing soil,imp roving soil,and stabilizing output.Thus it can promote the virtuous cycle of th e agriculture ecosystem.It was suggested to adopt the compound plant on fruit fa rming in eroded red soil area.
