2005年4、9月2次在安西极旱荒漠自然保护区北片黄草滩一带进行普氏野马在中国的再引入半放养试验.截至目前,半放养期间共繁殖野马42匹,平均生育率44.4%,平均成活率61.1%,年均增长率6.1%.通过对半放养的野马进行日常观测,结果表明:野马已在野外渡过了食物、水源、天敌防御等生存关,在野生性状恢复、繁殖、家族构成、种群结构、环境质量、生存状态、越冬和防御敌害等方面表现出一定的生态、行为和营养学方面的适应性,但野马繁殖率较低,存活率更低,狼袭、疾病、争斗受伤是野马死亡的主要因素.另外,保护区野马半放养工作还面临着科研工作滞后,近亲繁殖严重和种群数量增长缓慢等问题,并提出对策.%In April and September 2005, the semi-stocking experiment of the Equus przewalskii in China was carried out twice in the northern part of the Yellow Beach in the Anxi Extra-arid Nature Reserve.Up to now, Equus przewalskii bred was 42 in semi-stocking period , the aver-age fertility rate was 44.4%, the average survival rate was 61.1%, the average annual growth rate was 6.1%.The results showed that the Equus przewalskii defeat field condition, such as food, water, natural enemy defense, etc..Equus przewalskii showed ecological, behavioral and nutritional adaptability in aspects of the wild traits restoration, reproduction, family structure, population structure, environmental quality, survival status, overwintering and defensing enemy.But the Equus przewalskii breeding rate was low, survival rate was lower, wolf, disease, fighting injury were the main factors in the death of the Equus przewalskii.In addition, the Equus przewalskii semi-stocking work in protected areas was also facing the problems of lagged scientific research, serious inbreeding and slow growth of population, and put forward counter-measures.
