摘要: 在农牧户调查的基础上,将内蒙古自治区伊金霍洛旗11个典型村的82个抽样农牧户分为五类家庭农业生态系统:Ⅰ.种植业;Ⅱ.工副业;Ⅲ.种植业-畜牧业;Ⅳ.种植业-工副业;Ⅴ.种植业-畜牧业-工副业。采用组分优势度、结构优势度和复合系统稳定性指标,对五类农牧户的生态系统结构进行了定量评价。结果表明,农牧户生态系统的稳定性随经营内容增多和产业链延长而增强,并受退耕还林政策的影响。在退耕还林补助停发以后,各类型农牧户生态系统的均衡性和稳定性都不同程度的降低,尤其对以种植业为主的农牧户影响更显著。

Abstract: Based on the household survey, the 82 samples of farmer families in 11 typical villages at YiJinHuoLuo County in the Inner Mongolia Autonomous Region were classified into five types of household agro-ecosystems: Ⅰ.Planting; Ⅱ.Deputy industry; Ⅲ.Planting-animal husbandry; Ⅳ.Planting-deputy industry and Ⅴ.Planting-animal husbandry-deputy industry. The structure of these five different household agro-ecosystems was quantitatively evaluated by using component dominance, structural dominance and stability factor of complex system. The results indicated that the stability of the household agro-ecosystems was increased along with the increment of management diversification and the prolonging of industrial chain, and influenced by the policy of grain for green project. After the subsidy for returning cultivated land to forest was ceased, equilibrium and stability of the different household agro-ecosystems were deceased with varying degrees. The most significant impact was found on the farmer families engaging planting.

Key words: farming-pastoral transitional area, farmer household agro-ecosystem, structure
