摘要
川西横断山区气候寒旱,生态环境脆弱,水土流失严重,绝大多数草本植物返青晚、生长慢,人工草地资源匮乏,冬春季节牲畜饲草贮备不足。该文在对区域内牧草缺乏和生态问题现状进行阐述和分析的基础上,探讨如何利用高产牧草品种保护和恢复天然草地的新模式来缓解和释放天然草地载畜压力,对川西横断山区脆弱生态系统恢复和提高该地区草牧业市场竞争力具有一定意义。
The climate of Hengduan Mountain Area in Western Sichuan is cold and dry,the ecological environment is fragile,the soil erosion is serious,the vast majority of herbs turn green late and grow slowly,the artificial grassland resources are scarce,and the forage reserves in winter and spring are insufficient.On the basis of expounding and analyzing the current situation of forage shortage and ecological problems in the region,this paper discusses how to use the new model of protecting and restoring natural grassland with high-yield forage varieties to relieve and release the pressure of carrying livestock in natural grassland,which is of certain significance to the restoration of fragile ecosystem in Hengduan Mountain Area of Western Sichuan and to improve the market competitiveness of forage and animal husbandry in this area.
