摘要： 亚洲中部干旱区是北半球陆地温带、暖温带面积最大的世界干旱区域。同时，它又是世界上生态与环境十分脆弱，自然资源和能源相对富集的区域。从发生学的观点，用系统论的方法研究亚洲中部干旱区生态地理环境的发生、发展和演变过程，以满足区域经济建设和生态建设的需求。研究认为：山地森林草原-盆地平原绿洲寓于荒漠，并与荒漠共存，是一种复杂、而又完整的内陆生态地域系统，是亚洲中部干旱区最显明，最基本的自然生态地理区域，具有最根本的生态地理格局特征。深刻认识、科学掌握和解读干旱区的地域规律性——生态地理格局。对建设美丽中国，特别是中国干旱区生态安全、环境保护，促进社会经济可持续发展具有重要的理论和实践意义。

Abstract: The arid land in central Asia is the largest dry area located in the temperate and warm temperate zone of northern hemispheric earth.It is also the region characterized by very fragile ecology and environment and with plentiful natural and energy resources.It is necessarily that to reveal deeply the regional regulatory of eco-geographical pattern in order to meet the demands of ecological safety, rational utilization of natural and energy resources and social sustainable development.Thus, in this paper the evolution process of eco-geographical system in arid land of the central Asia is discussed in view of genetics and by using method of systemic theory.The main features of eco-geographical system is analyzed and the eco-geographical pattern is outlined according to regional geological geomorphologic, and climatic conditions and hydrological circulation process in arid land of the central Asia We recognize that the mountainous forest grassland-plain oasis in basins which is co-existed with desert constitutes a complex and complete eco-geographical system.This system is one of the most obvious and basic natural eco-geographical essence and characterizes the eco-geographical pattern in arid land of the central Asia.Obviously, to thoroughly understand this eco-geographical pattern will be of vital theoretic and practical importance to action on regional ecological restoration and reconstruction.The results of this paper can play an important role in formulating the strategy on sustainable social and economical development in arid land of central Asia.
