摘    要:本文记载了亚热带山区不同海拔高度:(1)草地植物生物量的季节动态;(2)草群地上部现存量和生长量的逐月动态;(3)牧草的再生性;(4)草地抗土壤浸蚀的能力及对放牧的适应等。这些资料有利于山地草地的合理利用和正确决定草地的利用制度和方法,从而实现亚热带山地草地在适度利用的同时,保持其生态平衡。这项研究也从草地生态经济领域为亚热带山区的良性生态设计提供了基本依据。

Abstract:This study deals with ecological economic characteristics of grasslands as optimum utilization of mountainous grasslands in subtropical zone of China. It has been laid out at five sites from different altitudes above sea level for four years. At the same time, some survey of cultivated grassland and others has been carried on in similar places. The valuable materials obtained include: (1) seasonal movement of plant biomass; (2) monthly movement of standing crop and growthrate; (3) herbage regrowth and (4) soil erosion resistance of grassland and adaptation of herbages for grazing etc. Based on these materials, farmers would decide exactly the initial and terminative grazing period, grazing season, stock capacity, grazing system etc. They would consequently help bring about the optimum utilization and maintain the mountainous grassland ecosystem balance. Besides, they would offer a fundamental basis for the mountainous ecological design in subtropical zones.
