【摘要】：采用相对资源承载力的研究方法,分析了2005—2014年天水市及各区县的各类相对资源承载力变化趋势。研究表明:无论以全国还是以甘肃省为参照区,2005—2014年天水综合承载力一直处于超载状态,且整体呈减小趋势,但综合承载力在2009年以后呈增加趋势。以甘肃省为参照区,天水各区县相对资源承载力仅有清水县一直处于富余状态,而在超载区县中,甘谷县的超载尤严重;以天水市为参照区,呈超载状态的有秦安县、甘谷县、武山县、张家川县。其中,甘谷县、武山县超载较严重,秦州区、麦积区、清水县呈富余状态。天水各区县的相对资源承载力区域差异明显,并且其发展对土地资源的依赖较大,因此为保证天水今后的可持续发展,必须要严格控制人口数量、适当增加耕地资源、加速区域经济发展、加强生态环境保护、节约能源等。
[Abstract]:By using the research method of relative resource carrying capacity, the variation trend of relative resource carrying capacity in Tianshui city and every district and county from 2005 to 2014 was analyzed. The results show that the comprehensive carrying capacity of Tianshui in China or Gansu Province has been in a state of overload from 2005 to 2014, and the overall capacity has been decreasing, but the comprehensive bearing capacity has been increasing since 2009. Taking Gansu Province as the reference area, the relative resource carrying capacity of Tianshui counties is only Qingshui County, but in the overloaded counties, the overloading in Gangu County is especially serious, and in Tianshui City, the overloaded counties are Qinan County and Gangu County. Wushan County, Zhangjiachuan County. Among them, Gangu County, Wushan County more serious overload, Qinzhou District, Maiji District, Qingshui County is surplus state. The regional difference of the relative resource carrying capacity of each district and county in Tianshui is obvious, and its development depends on the land resources. Therefore, in order to ensure the sustainable development of Tianshui in the future, we must strictly control the population quantity and increase the cultivated land resources properly. Accelerate the development of regional economy, strengthen ecological environment protection, save energy and so on.
