摘要
在对绿洲生态系统特殊性分析的基础上，运用灰色计量模型对２０００年河西走廊绿洲生态系统做了现状动态模拟和前景预测分析，提出了河西走廊绿洲生态环境质量改善的几种不同对策方案，认为以适度投入与适度产出为主要内容的可持续发展对策方案是保证河西走廊经济持续发展与生态环境永续良化的最佳对策方案。
Based on the analysis to the specific characteristics of oases ecosystem in some dry areas, the ecoperspective of oases ecosystems in 2 000 is evaluated by grey measurement model. The result shows that the quality of oases eec-environment could be ameliorered slowly, the improved area should be 11. 69× 104 hm2 more than that of degradation. However, the contra-dictoryes problems among the population, water, soil resources. environment and economic development will be faced to the local peoples seriously. thus, the establishment of eco-consciousness, the advocation of oases eec-ethics, eco-morality and eco-civiliztion, the construction of oases. eco-agriculture, and the fastening of eco-engineering construction and ecodesign are the main ecological stratiges for the improvement of dry area oases eco-environmental quality.
