转基因微生物生态学及大田释放风险评价研究

Ecology of genetically engineered microorganisms and risk assessment for their planned release

向环境中释放转基因微生物可能会带来一系列的安全问题．在大面积释放之前必须对转基因微生物在环境中发生基因转移的潜力、存活能力、扩散能力及对生态系统的潜在影响等进行生态学研究和风险评价，同时还要探索有效的检测方法和风险评价策略．该研究有助于分子生态学的发展和生物技术的安全应用，具有重要的理论和实践意义．

The environmental applications of genetically engineered microorganisms(GEMs) may cause many safety problems, It's necessary to assess the possible impacts of their planned release on ecosystems, with emphasis on the potential of horizontal transfer of artificially introduced genes between GEMs and indigenous microflora. and other ecologically important parameters like survival, dissemination and competition. It's also important to search for more valid methods of detection and to improve the strategy of risk assessment. The study is helpful for development of molecular ecology and application of biotechnology.
