【摘要】 解决"水草畜"平衡问题是促进干旱牧区经济和生态环境协调发展的关键。通过目标规划模型应用,计算了内蒙古四子王旗牧区草地资源承载力水平,明确了在人工种植冷季补饲型阶段和暖季放牧冷季舍饲型阶段的水资源开发利用率、可持续载畜量及所需灌溉饲草料基地发展规模。从研究区水量平衡、畜牧业产业结构及技术经济指标方面分析论证了水利化畜牧业在退化草地修复方面的可行性及其综合效益。更多还原

【Abstract】 It is essential to hold the equilibrium of regional water-grass-livestock for the harmonious development between economic and environment in arid pastoral area.The goal programming method was applied to calculate the grassland resources carrying capacity in Siziwang Banner,Inner Mongolia.The proposed model was applied to quantitatively study the water development,carrying capacity of grass resources and fodder land in two critical stages.These two stages are: the stage of artificial-planting-supplement-breeding in winter and the stage of grazing to pasture in warm season and stable breeding in cold season.Based on the analysis of water balance,pasturage structure and related technical and economic indexes,the paper proposed the feasibility and comprehensive benefit for the irrigation pasturage in degradation pasture restoration.更多还原
