通天河及江源区草畜平衡初步分析
Preliminary analysis of pasture-livestock balance in Tongtian River basin and Yangtze River source area
摘要
Abstract
Ecological environment in the Tongtian River basin and the Yangtze River source area is vulnerable and fragile,and most of the area is only suitable for growing pasture. Grazing is the major agricultural form, however the traditional grazing de-pends largely on weather conditions. The amount of grass yield per unit grassland is quite low,and overgrazing is one of the major causes for ecological damage to the natural grassland. Pasture-livestock balance issue in the Tongtian River basin and the Yan-gtze River source area is analyzed. It also points out that grassland quality and grass bearing capacity can be improved, overg-razing issue can be addressed,balance between feed and animal can be achieved and the ecological security of grassland can be maintained by a series of methods,including a overall banning on grazing on moderate-severe degraded grassland, letting the nature exerts its own restoration ability,developing artificial irrigation grassland at some appropriate areas and alternating tradi-tional grazing way.关键词
