摘要: 我国南方石灰岩荒山分布范围广阔,目前荒山上的植被和自然环境在人类长期掠夺性农业活动的干预下向逆向演替。对这种生产力十分低下的荒山如何合理利用是一个远未解决的问题。本文在对石灰岩山地环境逆向演替的过程、根源与危害和现有的各种利用方式作出系统分析与评价的基础上,提出了一种在石灰岩荒山发展豆科灌木饲料的新的利用方式。这种新的利用方式将有可能为石灰岩荒山的开发利用开创一条新路,也是南方石灰岩山区一项有深远意义的绿色工程。

Abstract: Widely distributed in the south of China, the limestone barren hills are a result of regressive succession under the intervention of long-term predatory farming activities of mankind. The productivity of these hills is low and how to make rational use of them is a problem to be solved. Based on systematic analysis and evaluation of the regressive succession in limestone mountainous regions and the various existing ways of utilization, this article presents a new way of utilization, that is, to produce leguminous bush fodder crops on limestone hills. This new way will make it possible to break a new path for the exploitation and utilization of the limestone barren hills, and it will become a green-project with profound significance in southern limestone mountainous regions.

Key words: limestone, barren hill, regressive succession, leguminious bush, green project
