摘要
在我国,人与草地的关系经历了4 个发展阶段,最终应发展成为草地农业生态系统,这是人类与自然和谐共处的可持续发展模式,人工草地的作用不容忽视。根据草地资源、草业经济结构和生产水平状况,我国西部10 省、自治区、直辖市可分为6 个发展区域,各区域可因地制宜地发展各具特色的草地农业系统,同时区域之间可以实行广泛的系统耦合;建议设立6 个草地农业示范项目和3 个研究性生产基地。
The relationship between human and grassland in China experienced 4 stages and should be developed into an agro grassland ecosystem in the end, which is the sustainable and mutual beneficial mode between human and nature, and artificial grassland played an important role. According to grassland resource, the structure of pratacultural economy and productive level, 10 provinces, municipalities and cities directly under the jurisdiction of central authorities in western China could be divided into 6 developing areas and they should properly build characteristic agro grassland ecosystem, meanwhile there could exist extensive system coupling between regions. The authors advise to build up 6 demonstrative projects and 3 productive bases for research.
