摘要
绿洲是干旱区特有的生态景观之一,也是干旱区人类生产和生活的主要空间。绿洲的稳定事关干旱区人类的生存、社会经济的发展。因此,绿洲稳定性成为近年干旱区研究的热点。从生态系统、景观、流域3个层次综述绿洲稳定性研究现状,提出在未来应建立高效节水绿洲的同时,还应加强田块、灌区和绿洲不同尺度水效益及其对绿洲水文循环影响的评价研究;加强以流域为单元,开展绿洲稳定性研究;加强人工绿洲建设与天然绿洲稳定的关系、流域内绿洲空间布局、结构与绿洲稳定性关系、绿洲生态用水和生产用水比例与绿洲稳定性的研究。
Oasis is one of the peculiar ecological landscapes in arid areas, and is the main space on which human beings rely for existence and development in arid areas. Human being existence and social and economic development are closely related to the stability of oases in arid areas. Therefore, oasis stability has become as a focus of researching arid areas since recent years. The research on oasis stability varies with landscape scales. In this paper, the present situation and the progress of the research on oasis stability at ecosystem scale, landscape scale and drainage basin scale are reviewed and summed up. It is suggested to pay great attention to the research on water efficiency at farmland, irrigated area and oasis scales and to the effects of oasis hydrological cycle while implementing water-saving irrigation in oases in the future. It is also suggested to pay more attention to the studies on oasis stability by regarding drainage basin as the basic unit, to the relations between the artificial oasis construction and the natural oasis stability, oasis stability and spatial distribution pattern and structure of oasis in drainage basin, and oasis stability and the proportions of water consumption for the ecology and production in oasis.
