摘要：

In many part of China, especially in its western part, animals were grazied on different areas in different seasons (Ren Jizhou et al.1978) due to apparent climatic effect.Based on the principles of seasonal animal husbandry and pastoral‐ agriculture ecological system, a new idea of critical pasture was developed.The critical pasture is defined as the pasture that had lowest carrying capacity in a particular season.In order to use 3S technology for pratacultural development, the new method of calculating carrying capacity of critical pasture was given.The new idea, target and method were validated in the project of.Change of Grassland Productivity and Counter‐measures in Aletai.
