摘要:

以黄土高原森林植被为重点,利用一定的论据讨论黄土无林论、草原次生论、厚层黄土观、400mm降水论、气候变迁论等立论的缺陷以及植被分区所存在的歧义。以排它法表明以延安一线、长城沿线等为标志的植被地带性原则的合理性,认为黄土高原具有森林发育的地带性环境。

Abstract:

It is necessary that primary vegetation situation under certain condition should be made clear for reconstructing degraded ecosystem, otherwise vegetation construction would be of considerable riskiness and blindness. Emphasis forest vegetation in the Loess Plateau was emphatically dealt with.From certain arguments the viewpoints have been discussed such as no forests in the Loess Plateau, secondary grasslands,thick loess,400 mm of precipitation,different interpretations in vegetation demarcation,and climatic change.Thus the reasonableness offor the vegetation zonality principle taking such marks as the demarcation lines on Yan’an and along the Great Wall was shown through exclusion. We believed that zonal environment was possessed in the Loess Plateau.

Key words: primary vegetation, forest, vegetation zonality, Loess Plateau
