不同放牧制度对裕民县山地草甸草原植被恢复再生长的影响

The Effects of Different of Grazing Systems on Mountain Meadow Steppe Plant Regeneration in Yumin County

山地草甸是畜牧业生产的自然资源,具有防风固沙、净化空气、涵养水源等多种功能,是许多国家发展畜牧业的重要基地。许多实验都证实划区轮牧和连续放牧在不同自然条件地区可能出现不同的结果,说明它对草地的影响很复杂。本文通过裕民县GEF项目的划区轮牧、自由放牧、禁牧和农牧民参与饲草地管理等措施,运用科学的监测手段,深入探究放牧制度对草地的影响,论证不同放牧制度的合理性和可行性,从而科学制定出符合生产实际的放牧制度方案,以减少资金浪费,达到保护草原,实现增产增收。

Mountain meadows are the natural resources of livestock production with the functions of wind sheltering and sand fixation, cleaning air, water conservation and so on, it＇s an important basis for livestock industry＇s development in many countries. Many experiments proved that rotational grazing and continuous grazing in／different natural conditions may turn up different results, it means that grazing method had complicated influences to grassland. The paper based on the outcomes of rotational grazing, free range, grazing prohibition and farmer participated forage land management from GEF program, by mean of scientific monitoring method to explore the influence of grazing system to grassland, and to expound and prove the Rationality and feasibility of different grazing plan. And, then to design a suitable and reliable grazing plan to achieve the aim of reduce the money waste and protect the grassland and increase the grass yield and farmer＇s income.
