内蒙古草甸草原家庭牧场模型模拟研究
The Modeling of Family Ranch in Meadow Steppe of Inner Mongolia
摘要
Abstract
Family ranch is the basic unit of grassland management in China, the operating management effects livestock production and grassland ecology directly, so the research on optimal management of family ranch had significant theoretical and practical meaning. The research was conducted in meadow steppe of Inner Mongolia, the herders incomes and the balance condition between forage and livestock were analyzed by using Optimized Management Models for Household Pasture Livestock Farm Production (OMMLP model), through the investigation of livestock, grassland, climate, economy and policy which relative to the family ranch productions and managements, finally we set up a typical household which is the average to the various index. The results showed that:The higher the stocking rate caused the more serious contradiction between pasture and livestock. When the stocking rate was 1.12 SE·hm-2, it reached the optimal balance between pasture and livestock, which means the forage supplied in winter may satisfy the livestock’s energy demand, while in summer, there were some surplus. The total operation expenditure of family ranch rose up with stocking rates increased, but the total revenue and net income showed a first increased then decreased trends with the increasing of stocking rates. The maximum net income showed up when stocking rate was 1.15 SE·hm-2. So keep stocking rates between 1.12~1.15 SE·hm-2 could make the family ranch at the best management level. It is an effective way to help households reaching maximum net income and to make the balance between forage supply and animal demand at an optimal level by ensure stocking rate is 1.12 SE·hm-2.关键词
