Trigonella arcuata responds to Seriphidium transillense desert degraded grassland

摘要

Xinjiang has 5 730 104 hm2 natural grassland including 1083.4 104 hm2 spring‐autumn pasture and S.transillense is the main spring‐autumn pasture which belongs to middle Asiatic climate desert that concentrates in northern Xinjiang plains and low mountains.The grassland has commonly degraded and some places have become over‐degradation because of unreasonable use through many years.With the increase of degraded degree, T.arcuata replaces S.transillense and becoming the dominant species.Fundamental researches have been done but lots of detailed researches are required including some species'strategies and mechanism for adapting natural environment of the degradation.
