【摘要】 近几年,由于人类对草地过度干扰,使其生态功能受到严重影响,其干扰作用在荒漠草原影响尤为显著。关于荒漠草原不同放牧强度对生态系统服务功能的影响一直备受国内外研究者关注,本研究通过对短花针茅(Stipa breviflora)荒漠草原的地上植被指标、土壤成分指标并结合市场价值体系,估算出不同放牧强度下9个生态服务功能的价值量,并对各个生态系统服务功能的总价值进行研究。更多还原

【Abstract】 Grassland ecological function has been severely affected,and its interference effect has been particularly significant in desert grasslands due to the excessive human disturbance to grassland in recent years.The effect of different grazing intensities on ecosystem service function in desert steppe has attracted the attention of researchers at home and abroad.This study estimate the value of the nine ecosystem service functions under different grazing intensities by using the above-ground vegetation indicators,soil composition indicators and the market value system in Stipa brevifloria steppe,and researches the total value of each ecosystem service function.更多还原
