回溯中国西南岩溶地区草地—畜牧系统的开发研究

Review on the exploitation and research of grassland animal husbandry system in southwest Karst Area of China

西南岩溶地区地形地貌特殊 ,是少数民族的主要聚居区之一。由于长期不适宜的开发 ,生态破坏严重 ,面临严峻的脱贫致富任务 ,但该地区同时蕴藏丰富的资源 ,优势明显 ,潜力巨大。改革开放以后 ,国内许多研究机构和有关省区的规划研究部门在各自领域进行了深入细致的研究 ,积累了可观的资料 ,为岩溶地区科学适度开发提供了科学依据和示范模式。甘肃省草原生态研究所较早介入我国南方草地的开发研究 ,尤其是岩溶地区的开发研究。文章系统总结 2 0年来 ,主要是“六五”至“八五”期间 ,以甘肃省草原生态研究所为主的科研力量在西南岩溶地区草地—畜牧系统开发研究中 ,探索成功模式和经验 ,在分析岩溶地区发展潜力和优势的基础上 。

There are special landforms in the Karst area of the southwest China, in which 48 minorities have lived for generations. Without the long term proper exploitation, the ecological environment were damaged seriously and the eradication of poverty played the key role of the sustainable development in this area, however in which there were the abundant resources and grand potential. Many domestic and abroad institutes including the institutes in the involved provinces gave a lot of research and got the abundant data, which supported the scientific basis and demonstration mode to make a strategic decision of the sustainable development in Karst area. Gansu Grassland Ecological Research Institute early carried out the study on the grassland in southern China, especially in the karst area. This paper systemically reviewed every research in the latter 20 years, especially successful mode and experience developing the agro grassland system in the Karst area conducted by Gansu Grassland Ecological Reasearch Institute from the sixth to eighth five year plan. Based on the detailed analysis of potential and advantage, the urgent problem were suggested.
