| 摘 要： | 基于季节畜牧业和草地农业生态系统的思想,提出了关键场的新概念;基于3S技术的应用和草业发展的需要,提出了关键场载畜量计算的新方法,为草地退化的防治和草地畜牧业的可持续发展,提供一个新的视角和可操作的评价指标;这些新的概念、指标、方法和程序,已经在<中国西部阿勒泰地区草地生产力变化及对策研究>中得到验证;草地畜牧业的核心问题,就是全年放牧的草畜平衡问题,这一点已列入草原法.因此,这些成果,可为新形势下正在起步的我国草原监理事业,提供必要的技术支撑.

| Abstract: | Based on the concept of seasonal grazing production systems and agro-grassland ecological systems, the new idea of key pasture has been formed. In order to use 3S technology for prataculture development, a new method for calculating the stocking density of key pasture has been produced. The new idea and method was validated in a project termed'Change of Grassland Productivity and Counter-measure in Aletai', which could offer an operable estimate target in a new visual angle for the sustainable development of a grassland live stock production system. Further, it could give the technology support for a start to grassland monitoring and management in China. |
