摘要:
通过实地踏查、调研和大量资料分析,综合运用生态学、景观生态学、区域发展与规划以及水土保持学等多学科理论,结合退耕还林还草与经济发展的客观实际,构建了黄土高原不同立地条件下的植被营建技术模式。同时,提出开发利用相应立地条件下天然草地的优势种和主要伴生种,以丰富扩大植被建设所需的植物材料。

Discussions on vegetation-building patterns and natural herbage plants using in different physiognomy sections in Loess Plateau
Abstract:
By investigating and studying on the spot and consulting lots of data,this paper set up some vegetation-building technique patterns in physiognomy sections in Loess Plateau according to the theoretical knowledge of ecology,landscape ecology,developing and planning on district and soil and water conservation etc.,as well as the facts of "the project of conversion of cultivated-slope-land into forestry and grassland" and the economic development characters in this area.To enrich plant materials for vegetation building,this paper also put forward the idea of exploiting the dominant herbage and companion grass of natural pasture.
Key words:  Loess Plateau  vegetation building pattern  physiognomy condition  natural herbage plants
