甘肃省麦积山景区——生态过渡带自然和文化遗产杰出范例

直到现在，生物多样性管护的主要注意力放在热点地区，但T．B．Smith等生态学家提出，管护战略必须把注意力不仅放在热点地区。而且也耍放在相联系的过渡带。他们争论说后者区域可能保有许多种群之间的适应变异，并因而对于生物多样性的产生和保持很重要。虽然生态过渡带常常拥有高的物种丰富度，但它们大多数是广泛分布的物种，它们的分布范围在生态过渡带相遇。甘肃省的麦积山景区是我国生态过渡带的自然和文化遗产地的杰出代表。麦积山景区不仅具有温凉、半湿润、四季分明的气候和复杂的地质地貌与土壤条件，使它的生物多样性独特丰富，具有过渡的特点，为我国同纬度其它地区无法相比，它的古文化遗存也丰富多彩，在一定程度上展现了印度佛教文化向中国化的过渡。

Scenic area of Maijishan, Gansu Province: outstanding example of natural and cultural heritages in ecological transitional zone

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 biodiverslty. 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.
