黄土高原坡耕地生态退耕的植被建设研究——以陕西省黄土高原生态退耕县为例

The investigation of the vegetation construction of biologic comeback in sloping plow of the Loess Plateau:in Shaanxi Province

通过对陕西省黄土高原地区生态退耕县坡耕地的数量、质量调查,指出实现坡耕地退耕的措施,提出在各生态类型区的自然条件下适宜种植的树种、草种和提高植被成活率的途径,分析坡耕地生态退耕后植被建设将带来的经济和生态效益,对整个黄土高原地区的植被建设具有重要的指导作用。

The vegetation construction of biologic comeback in sloping plow of the Loess Plateau is the most important act in improving the environment of this area.Taking the Loess Plateau in Shaanxi Province as example,the measures of carrying out biologic comeback in sloping plow are expounded.The appropriate growing vegetation of different biology area is analyzed,and the approaches of improving the vegetation surviving rate are pointed out.The vegetation construction of biologic comeback will bring great economic and biologic benefit,and will offer important guidance to the vegetation construction in the Loess Plateau.
