基于生态足迹的甘孜州与内蒙古草地生态安全对比研究

Contrast Study on Grassland Ecological Safety Based on Ecological Footprint between GanZi Prefecture and Inner Mongolia

甘孜州与内蒙古草地资源都十分丰富,都面临畜牧业的发展与草地保护问题,其生态安全都备受广泛关注。本文利用生态足迹评价模型,计算甘孜州与内蒙古1995-2008年草地生态足迹,并对其生态安全进行了对比研究。结果表明,甘孜州与内蒙古草地都处于生态不安全的状态,但由于人口、经济、城市化水平等因素的差异,导致甘孜州与内蒙古生态安全差异较大,人类生产生活对内蒙古草地的不利影响较大。甘孜州农牧业的发展应以内蒙古为鉴,坚持"保护第一、利用第二"的原则,在保护好草地生态环境的同时,搞好藏区农牧民经济的发展。

grassland resources are very abundant in Ganzi Prefecture and Inner Mongolia,faced with the development of animal husbandry and grassland protection,ecological safety causes people＇s extensive attention.This paper used the ecological footprint model to calculate the grassland ecological footprint during 1995-2008 in Ganzi prefecture and Inner Mongolia,and made comparative study of the ecological safety.Results indicated that insecurity of grassland ecosystem in Ganzi Prefecture and Inner Mongolia,however,because of differences of population,economy,urbanization and etc,leading a larger ecological security difference between in Ganzi Prefecture and Inner Mongolia.Human production and living had a larger dverse effects on grasslands in Inner Mongolia.To take warning from Inner Mongolia,Ganzi Prefecture should adhere to ＂protection first,using second＂ in Agricultural development.We should protect the grassland ecological environment and improve the economic development of Tibetan farmers and herders at the same time.
