摘要 针对轿子山飞播示范草场的植被与开发利用现状进行调查研究,通过对轿子山草场进行实地踏勘和测量,对播区内与周边农户进行走访、座谈,对参与飞播和飞播后从事过该草场承包经营、科研、补植补种、复垦、管护的相关人员进行了解,在查阅大量档案资料的基础上,指出了轿子山飞播示范草场成功建设的借鉴意义,以及草场在管理利用中存在的问题,并提出了相应的开发利用建议,旨在为轿子山草场及同类型草场的合理开发利用提供科学依据。

Abstract According to the vegetation and development status of Jiaozishan Aerial Seeding Demonstration Pasture, spot surveying and measuring were carried out. Farmers in and around the sowing area were visited. Related personnel were investigated who participated in aerial seeding, contract operation, scientific research, reseeding, reclamation, management and protection. Based on a large amount of deposited document, problems in pasture management and utilization were pointed out. Corresponding suggestions on development and utilization were put forward, which provided scientific references for the successful construction of Jiaozishan Aerial Seeding Demonstration Pasture, and the development and utilization of Jiaozishan Aerial Seeding Demonstration Pasture and the same types of pastures.

轿子山草场是贵州省织金县三片大型天然草场之一,位于织金县城西部,距县城46 km,地理坐标为105°28′~105°32′ E、26°36′~26°41′ N。1984年国家投资24万元建立飞播示范草场1 333 hm2。笔者于2015年11月21日~12月7日对轿子山草场进行了实地踏勘和测量,对播区内及周边农户进行走访、座谈,对参与飞播和飞播后从事过该草场承包经营、科研、补植补种、复垦、管护的相关人员进行了解,同时查阅了大量的档案资料,以期全面掌握轿子山草场飞播前后的植被变化情况,探索喀斯特山区成片天然草场改良途径与发展方向。
