摘　　要：在我国南方地区 ,西部天然牧地的营养价值与东部比较接近 ;生产力后者较高 ;生产量前者显著高。中高山地带天然牧地的营养价值高于丘陵低山地带 ,但生产力和生物生产量低于后者 ;营养生产量 ,西部以前者高 ,东部以后者高。与北方牧区比较 ,南方地区天然牧地的生产力较高 ,营养价值和生产量较低。从开发潜力看 ,南方地区西部高海拔地带以人工牧地较大 ;东部以农林用地生产饲用植物的较大。In the south area of China, the nutrition value of natural rangeland in the western part is similar to the one in eastern part, while the latter has a higher productivity. The nutrition value of natural rangeland on mid-high mountain area is higher than that on low hills, but the productivity and biomass are lower. Compared with northern rangeland, the southern area has higher productivity and lower nutrition value and yield. As far as development potential is concerned, artificial grassland in western high land and eastern agricultural land can achieve high potential.
