Analysis of the temporal and spatial variation of man-grain relationship during 1999 to 2014 in Henan Province
摘要
Abstract
From the perspective of the variation of man-grain relationship,this paper analyzes the change of man-grain relationship in Henan Province from 1999 to 2014 at the provincial level,and researches the temporal and spatial variation of the man-grain relationship and its causes at the urban level,and provides the basis for timely adjusting and formulating the strategy of grain production of the whole province,and the basis for the targeted measures of cultivated land protection.The results shows that:(1) The entire provincial cultivated land carrying capacity shows a rising tendency as a whole,and the rate of the cultivated land carrying capacity has reduced from 0.87 to 0.69 during 1999 to 2014,with a surplus,the entire provincial grain supplyare self-sufficient,,and its contribution rate to the national food supply did not fall but increased;(2) the man-grain relationship has the significant regional differences,and in Pingdingshan,Jiyuan,Luoyang,Sanmenxia and Zhengzhou,the food production cannot meet the demand of consumption,and other 13 cities are self-sufficient and have achieved a surplus.In general,the grain production of Henan province is in a safe condition,and its contribution rate to the national food supply maintains a growing tendency,however,the regional differences are obvious,the cities whose carrying rate increases should strengthen farmland protection,and curb the deterioration tendency of man-grain relationship.关键词
