摘要
Abstract
On the basis of man-grain relationship,using the land carrying capacity (LCC) and land carrying capacity index (LCCI) models,the spatial-temporal variation of land carrying capacity was quantitatively evaluated in Guizhou Province from 2000 to 2015 on basis of 3 spatial scales which were province,city and county.The results showed that:Observed from Guizhou Province level,the land carrying capacity has been in states of population overloads and food shortages;Observed from spatial patterns,the cities (states) of food surplus were increased and man-grain overloads were decreased,the man-grain relationships was improved,the land carrying capacity was lowest in Zunyi and highest in Guiyang.Observed from counties scale,the land carrying capacity of most countries were obviously improved,the land carrying capacity of northern countries were significantly higher than other countries,the food surplus countries mainly distributed in Zunyi,and the population overloads countries mainly concentrated in Guiyang-Anshun-Liupanshui-Qianxinan.关键词
