中国草业生态经济区初探

A preliminary discussion on grassland ecological economic regions in China

根据生态条件的相似性 (尤其是水、热条件的相似性 )、草地类型和景观的相似性、草业系统生产层的结构和生产内涵的趋同性、草地生态系统与经济系统的内涵与外延的相似性、草业发展对策和关键技术的相似性和草业生产区域规划的组织与实施的空间可操作性 (即一定级别上行政区划界限的完整性 )等 6项原则 ,我国可划分为 7个草业生态经济区 :蒙宁干旱草原草业生态经济区、西北荒漠灌丛草业生态经济区、青藏高寒草业生态经济区、东北森林草业生态经济区、黄土高原—黄淮海灌丛草业生态经济区、西南岩溶山地灌丛草业生态经济区和东南常绿阔叶林—丘陵灌丛草业生态经济区。以自然条件和草业生产现状为基础 。

Based on 6 major criteria of classification, that is, similarities existing in 1) ecological conditions, moisture and temperature in particular, 2) grassland types and landscapes, 3) grassland production and its structure, 4) consistence between grassland systems and econoimc systems, 5) consistence between grassland development policy and critical technology available and 6) practicability of organisation and administration for regional grassland development programming, the following division of 7 grassland ecological economic regions in China is suggested:1) Inner Mongolia Ningxia Arid Grassland Region, 2) Northwest Desert Shrubland Region, 3) Qinghai Tibet Highland Region, 4) Northeast Forest Grassland Region, 5) Loess Plateau and Huang huai hai Shrubland Region, 6) Southwest Karst Shrubland Region and 7) Southeast Forest Shrubland Region. For each of the above regions specific development policy and approaches are also discussed.
