摘  要:
为了弄清白银市的资源承载能力水平,运用相对资源承载力的研究思路,分别以全国、甘肃省和兰州市作为参照区,动态分析了该区域1996~2005年各种资源的相对承载力以及综合资源承载力。结果表明:①与全国或兰州市相比,白银市的综合资源承载力均处于超载状态,但近年来超载程度有所下降。2005年末,综合资源承载力均约为163万人,尚超载12万人。②与甘肃省相比,白银市的综合资源承载力处于富余状态,且有上升的态势。2005年末,综合资源承载力为231万人,富余56万人。③白银市自然资源对其综合资源承载力的贡献都最大,均在42%以上,是综合资源承载力的主要贡献源。以全国为参照区,社会资源对资源承载力增长的贡献最大,自然资源最小;以甘肃省为参照区,经济资源对资源承载力增长的贡献最大,自然资源最小;以兰州市为参照区,自然资源对资源承载力增长的贡献最大,社会资源贡献最小。

摘  要:
By using the research conception and the calculation methods of the relative carrying capacity of resources,the authors analyze the relative carrying capacity and evolution of resources in Baiyin city during the last 10 year period from 1996 to 2005 compared with that in the whole country,Gansu province,and Lanzhou city.Thus conclusions were drawn.①No matter com- pared with the whole country or Lanzhou city,the synthetic capacity of Baiyin city has been in the state of overloading.The nat- ural resources are relatively enough,and other resources are overloaded.In the end of 2005,the overloaded population is 120 thousands persons;②Refer to Gansu province,the synthetic capacity of Baiyin city has been in the state of relative enough. From 1996 to 2002,the social resources are overloaded;In the last 3 years,all resources are relatively enough;③Thecontribu- tion of the carrying capacity of natural resources to the carrying capacity of synthetic resources,which is greater than 42 per- cent,is much higher than that of the carrying capacity of any other resources.Based on different reference region,the contribu- tions of different resources to the increase of carrying capacity of synthetic resources are different in study region.
