Till now, the main attention concerning conservation of biodiversity is laid on hot spot, yet Smith et al. suggest that conservation strategy should focus not only on hotspots but also on associated transitional zones. They argue that the latter regions might hold much of the adaptive variation between populations, and might therefore be important for the generation and maintenance of biodiversity. Though the transitional zones often hold high species richness, they are generally widespread species whose ranges meet at the ecotones. Scenery district of Maijishan, Gansu Province is a representative example of natural and cultural heritages in ecotone in China. Its climate is mild and semi-moist, with distinct four seasons, and has complex geology, geomorphology and soil conditions, so its biodiversity is distinctive and rich, with transitional character, incomparable with other regions of the same latitude in China. Its old culture remnants are also rich and varied, and reveal the transition from Indian Buddhism culture to Chinese culture.
