Analysis on development of Xanthoceras sorbifolia industry in Gansu Province

The central, east and southeast region of Gansu province are mostly the gully region of Loess Plateau, in which forest vegetation is sparse and the ecological environment is very fragile. The rainfall in these regions is mainly concentrated between July and September, and 30%～50% of the precipitation is in the form of rainstorm. Thus, there is serious side by side contradictions between drought and soil erosion in these regions. According to analyze systematically on the adaptability Xanthoceras sorbifolia, the central, east and southeast region of Gansu province are confirmed to be suitable area for its cultivation. Investigation showed that the area of barren hills suitable for growing Xanthoceras sorbifolia in large scale is 390 000 hm2. The factors restraining development of Xanthoceras sorbifolia，as well as the corresponded solutions, had been discussed in the end of this paper.
