摘要
针对黄土高原植被建设中存在的覆被率低 ,造林成活率、保存率低和效益低等问题 ,提出了只有在生态效益、树种选择等方面转变观念 ,才能切实搞好植被建设 。
There are some problems in the vegetation construction in the loess plateau region, such as the low rate of vegetation cover, the low survivorship and preservation rates of afforestation, and the low economic benefit. It can be done better if only the idea about ecological efficiency and tree species selection is changed. The great problems about vegetation construction are put forward.
