| 摘 要： | 农牧过渡带 (或农牧交错带、半农半牧区 )是指我国传统种植业区和传统畜牧业区的镶嵌结合地带。近世纪以来 ,由于人口剧增 ,垦草种粮面积不断扩大 ,滥垦、过牧、滥樵 ,使草地植被大面积消失 ,沙漠化和荒漠化日趋严重。据报道 ,目前我国北方农牧过渡带荒漠化土地面积已达 1 6 7×10 5ｈａ ,占土地总面积的 5 2 73% ,年增长率约为1 39% 3] 。赤峰市是我国北方农牧过渡带较典型、分布面积较大的地区。该地区资源类型丰富 ,互补优势明显 ,特别是农牧结合的潜力巨大。但长期以来这里区域生态环境恶化加剧 ,导致严重的贫困化。解决这一问题的关…

| Abstract: | Six households agricultural production systems were defined based on investigating and analyzing production situation of households in 3 geo-economic districts in transition zone of cropping and pasture(Chifeng, Inner Mongolia).Three production systems, e.g., pasture-pig system, cropping-cattle fattening system and agro-animal husbandry system, were selected through ecological assessment. The improved suggestion for the systems was provided according to existing problems of these systems. |
