摘要: 绿洲系统承载力是生态承载力、生产承载力与生活承载力3种承载力相互耦合的产物。绿洲系统生态—生产—生活承载力相互作用的驱动机制主要通过水资源、投资和人口三大核心因子的驱动进行,实现水资源生态效益、经济效益与社会效益最大化的内在驱动,决定着绿洲系统生态—生产—生活承载力的最佳组合方式。在边际效益递减规律约束下,投资分配的最佳比例取决于单位投资效益的差异。人口通过改变核心驱动因子———水资源与投资的稀缺程度,在绿洲系统生态—生产—生活承载力相互作用驱动机制中起着双重作用。

Abstract: Capacity of oasis systems is the result of mutual coupling by ecological capacity,eco-nomic capacity and social capacity.The mechanism of ecological-economic-social capacity inter-actions is driven by core factors of water,investment and population.The interior drive to realize the maximum ecological,economic and social benefit s of water factor decides the optimizing as-sembled ways of ecological-economic-social capacities.Under restriction of boundary benefit de-gression law,the optimum proportion of investment distribution lies in difference of unit invest-ment benefit.Population factor has double functions in the mechanism s of ecological-economic-social capacity interactions via changing the deficient degree of water resources and investment.

Key words: oasis systems, ecological-economic-social capacity, driving mechanism
