Spatial‐temporal landscape dynamics in the Hulunbeir forest‐steppe ecotone

摘要

The forest‐steppe ecotone with alkalized grassland is in Hulunbeir, which borders the Great Xing'an forest region is one of the most significant ecological barriers in North China.In the last decades, due to the changes of global climate and the general impacts from human activities, timberline in the transition region moved up, grassland changed into desert and the water and soil lost drastically.All these factors, in combination, severely hamper the sustainable development of local resource, environment, economy and society.Nowadays, researches on dynamic changes of landscape structure and function characteristics are still few.
