Abstract: Karst rocky desertification is a kind of ecosystem degradation phenomenon, which can lead to soil degradation, land nutrient reduction, low land productivity, water pollution and other ecological environment problems, so it seriously threaten the ecological and environmental safty and social economic development of karst areas in China. This paper introduced the characteristics of agricultural production in Guizhou karst region, a typical karst region in southwest China, and reviewed the application of effective microorganisms (EM) in the unconventional feed resources development, animal husbandry, aquaculture and planning industry, and looked forward to the application prospect of EM bacteria in agricultural production in karst region of Guizhou with aimto provide some references for the sustainable development of ecological agriculture in karst region of Guizhou.

Key words: Karst rocky, desertification, effective microorganisms, agricultural production, animal husbandry

摘要： 喀斯特石漠化是一种生态系统退化现象，可导致土壤退化、土地养分锐减、土地生产力低下和水体污染等生态环境问题，严重威胁我国喀斯特地区生态环境安全及社会经济发展。以中国西南典型喀斯特地区——贵州喀斯特为例介绍了喀斯特地区农业生产的特点，综述了有效微生物菌群（effective microorganisms,EM）在非常规饲料资源开发、畜牧业、水产养殖及种植业中的应用，并展望了EM在喀斯特地区农业生产中的应用前景，旨在为贵州喀斯特地区生态农业的可持续发展提供一些参考。
