摘　　要：中国南方草地区为秦岭、淮河以南、青藏高原以东的广大地区 ,总面积约 2 70万 km2 ,分属淮河、长江、珠江 3大流域。南方草地多山 ,本文涉及的 12个南方省区中 ,山地与平原之比平均为 4 .85∶ 1,比全国平均比值高出 1倍。山地面积之大小与青藏高原距离的远近呈负相关。南方草地大体可以分为云贵高原区、华东区和华南区。笔者提出建立 3类系统耦合经济带 ,即西南岩溶山地系统耦合生态经济带、江淮平原丘陵系统耦合生态经济带和岭南沿海平原丘陵生态经济带。每一生态经济带内包含中心城市 ,农村生产基地和社会支持系统。据初步估算 。The grasslands in the south of China are distributed in a vast geographical area on the south of the Qinling Mountain Range and the Huaihe River and on the east of the Qinghai Tibet Plateau, consisting of the three river basins of Huaihe, Changjiang and Zhujiang and with a total area of 2.7 million square kilometres. The geographical area is mountainous and in the 12 provinces or regions mentioned in this paper the average area of mountains is 4.85 times as much as that of plains and 2 times as the national average. The area occupied by mountains in each province or region is negatively correlated to the distance between its location and the Qinghai Tibet Plateau. The grasslands in the south of China could be roughly divided into 3 geographical sub areas, that is, Yunnan Guizhou Plateau, Eastern China and Southern China, and in each of them a System Coupling Ecological Economic Region could be established, which would consist of urban centres, rural production bases and social supporting networks and, at a proimary estimate, possess great economic potential.
