江西红砂岩侵蚀劣地综合治理模式研究探讨
|
摘要
江西省红砂岩发育土壤分布面积广,但遭受到强烈的土壤侵蚀,土壤质量严重退化,成为水土流失治理迫切需要解决的问题。通过实地调研和现场试验示范,结合生态恢复和开发利用2个主要治理方向,总结提炼了适合于江西省红砂岩侵蚀劣地的5种典型治理模式。在生态恢复治理方向下:(1)大封禁+小治理模式;(2)灌草植被带模式;(3)竹节水平沟+乔灌草混交模式。在农林开发治理方向下:(1)反坡梯田+经果林开发模式;(2)生态路沟+鱼鳞坑+经果林开发模式。最后从侵蚀机理和综合治理模式等方面展望了该研究的前景。
As a widely distributed soil type in Jiangxi province,red sandstone soil has suffered from strong soil erosion,and the soil quality was seriously degraded. Through field investigation,experiment and demonstration,we summarized and refined 5typical control models suitable for red sandstone eroded badland in Jiangxi province from the control directions of ecological restoration and agricultural development. In the control direction of ecological restoration,there were 3 models:( 1) large prohibition +small soil loss control model;( 2) shrub-grass vegetation belt model;( 3) bamboo-type contour trench + mixed arbor-shrubgrass model. In the control direction of agricultural development,there were 2 models:( 4) reverse-slope terrace + economic fruit forest development model;( 5) ecological road-ditch + fish-scale-like pit + economic fruit forest development model. Finally,the author discussed the research prospects of red sandstone eroded badland from the aspects of erosion mechanism,comprehensive control model and so on.
