中文摘要：

对于内陆湖泊，由于存在补给能力小、换水周期长、咸化趋势明显等自身的一些特性，开发利用中的保护显得尤为重要，而湖泊本身又是内陆地区极为重要的经济源泉，不可能不去开发。如何在利用的同时又达到保护的目的？本文以岱海为例，通过对藻类生长环境和潜在经济价值的分析，以及对西部湖泊资源条件和新技术的综合运用，探讨了利用湖泊自身条件和特殊的技术手段，在内陆湖泊进行封闭式管道化微藻生产的可行性及若干优势，尤其在农业新产业价值和避免污染以及减少湖面蒸发方面，进一步提出了在广大西部湖区推广微藻养殖的理论及现实意义。

英文摘要：

Lower capacity of water supply, long water exchange cycle and salted trend are characteristics for most of the inner lakes. Lakes can＇t avoid to be used being an important economic resources for inner lands, So protection of lakes becomes important during the process of development. How to make the utilization and protection coincidence？ This research gives out the feasibility and the advantages of breeding alga in Daihai Lake with special technical device, especially in decreasing pollution and evaporation by analyzing the lake resources and new technology, and as an addition put forward the theory and realism significance of breeding alga in west area.
