北方农牧过渡带农户农业生产系统模式评价与优化研究

A study on assessment and improvement for agricultural production systems of households in cropping and pasturalism transition zone in North China

摘要

摘要: 以内蒙古赤峰市为例，采用切诺斯评价法对北方农牧过渡带典型地区的偏牧区、偏农区和半农半牧区3种类型区常见的6种家庭农业生产系统模式进行了社会经济效益、生态效益和资源利用效率的系统评价与优选，结果表明草地畜牧业和养绪模式、种植业和育肥牛模式、农牧结合模式效益较好，并针对3种模式存在的问题提出优化改良方案，改良后的优化模式分别比原模式户均收入提高26．8％、81.0％和46．9％，投资效益提高4．7％、7．1％和4．2％；产出总能分别提高27.0％、77．0％和7O．5％；光能利用率分别提高14．6％、23．8％和47.6％。

Abstract: 6 households agricultural production systems are defined based on investigation and analysis of production situation of households in 3 geo-econoiTlic districts in transition zone of cropping and pastoralism (Chifeng，Inner Mongolia)．These production systems are assessed in soci-economy，ecology and resource utilization efficiency(RUE)by using comprehensive assessment system．The results show that pasturalism-pig system，cropping-cattle fattening system and agroanimal husbandry system have good benefits The improved plan for the systems is provided according to the existing problems of these systems．Compared with original systems，household income of improved systems increases by 26．8％，81．0％ and 46.9％；the investment result raises 4．7％，7．1％ and 4．2％；the light energy utilization efficiency increases by 14．6％，23．8％ and 47．6％．
