Based on observation of vegetation quadrates of abandoned farmlands in Ansai
a loess region of hills and gullies
vegetat ion communities and their dominant species were ascertained through TWINSPAN. Results show that there are mainly 4 vegetation communities: Artemisia scoparia dominated community
Lespedeza davurica and Stip a bungeana dominated community
Artemisia gmelinii dominated community
and Bothriochloa ischaemum dominated community. The Canonical Correspondence Analysis reveals that the year since abandonment
total phosphorus
exchangeable phosphorus and soil water content are important factors significantly effecting the variation of species in abandoned croplands. Along with the life-form characteristics
it is considered that Bothriochloa ischaemum and Lespedeza davurica have strong adaptation to site conditions
and could be the proper introducing species in abandoned croplands to accelerate and direct vegetation community succession and control soil erosion on the hilly-gullied loess plateau
