摘要
坡耕地不仅是人们赖以生存的重要生产资料,同时,也是水土流失最为严重的一种耕地类型,成为水土流失的主要策源地。在多年的实践中探寻到植物篱结构能有效改善坡耕地水热条件、加强渗透水流、减少地表径流,从而达到控制坡耕地水土流失的效果。本文概述了国内外植物篱的起源发展,植物篱在国际上的研究始于20世纪70年代末,80年代末引入贵州,90年代初期植物篱模式在我国开始兴起,90年代后期植物篱的试验研究逐步扩大。国内外学者主要针对植物篱种类、植物篱水土保持生态经济效应、植物篱减蚀机理、植物篱根土复合体固土机理等开展了大量研究,取得了丰硕的科研成果。最后,对植物篱模式的建设提出了几点建议。
Slope farmland is not only a necessary means of production ,but also the most serious type of cultivated land in soil and wa‐ter loss and thus the main source of soil and water loss .Over many years of practice ,it is explored that the hedgerow structure can effectively improve the water and heat conditions of slope farmland ,strengthen the infiltration of water and reduce surface runoff ,so as to prevent soil erosion on slope farmland .This paper reviews the origin and development of hedgerows in China and foreign coun‐tries .Hedgerow study began internationally in the late 1970s and was introduced in the late 80s to Guizhou City ,China .With the rise of hedgerow pattern in China in the early 90s ,experimental research on hedgerows became gradually expanded in the late 90s . Domestic and foreign scholars achieved fruitful results through a great deal of research mainly on hedgerow species ,economic and ec‐ological effects of hedgerow soil and water conservation ,mechanism of reducing erosion ,mechanism of soil‐root fixing Furthermore , this paper puts forward some suggestions on the construction of hedgerow patterns .
