- Abstract:
-
In order to analyze dynamic variation characteristics and future development tendency of grain and cultivated land coupling system in Heilongjiang Province, based on constructing evaluation indicator systems of grain production and cultivated land use in Heilongjiang Province, the development process and coupling situation of two systems from 1980 to 2010 were analyzed by using principal component analysis and coupling model. The results showed that: (1) the trend of two systems was similar and increasing; (2) the evolution speed of cultivated land use was greater than grain production from 1980 to 1990, but the period of 1990 to 2010 was opposite; (3) the coupling situation of two systems experienced coordination to incoordination, then to coordination. Cultivated land potential should be utilized deeply and grain production capacity should be enhanced effectively, at the same time, the coordinated development of them should be promoted actively.
