区域耕地面积时空变化特征及驱动力分析——以我国中部地区为例
Analysis on temporal and spatial variation characteristics of regional agricultural acreage and its driving force——A case of Central China area
摘要
Abstract
[Objective]The present research was aimed to provide the theoretical references for harmonious development of economy and society in six provinces of Central China,as well as the protection and sustainable utilization of cul-tivated land and its related research. [ Method ]Temporal and spatial variation characteristics of agricultural acreage change and its driving force factors in six provinces of Central China were analyzed by literature analysis and principal component analysis,respectively. [Result]Regarding temporal characteristics analysis,during 2000-2010,agricultural acreage change of the six provinces showed the trend of "increase-decrease-increase-decrease",and farmland utilization showed the trend of "decrease-increase-decrease-increase". Despite obvious regional differences in land utilization,agricultural acreage varied only little among the six provinces. Fifteen driving factors,which affected the change of arable land in Central China,were divided into three categories,namely socio-economic driving factors (which consisted of population and economic development),agriculture driving factors (which comprised of agricultural science and technology,and a-gricultural production ) and policy driving factors (urban land use). [ Suggestion ] It was suggested that except Shanxi,the other five provinces,viz.,Anhui,Jiangxi,Henan,Hubei,and Hunan,should strengthen field engineering construction based on farmland water conservancy facilities and improve agricultural cultivation pattern and technical support and service system in order to consolidate the status of national key commodity grain production bases. Shanxi,on the other hand,should focus on southern and middle grain production counties,which includes promoting infrastructure construction of drought resistant water source and farmland water conservancy,enhancing soil fertility and water and soil conservation for protecting arable land,extending high yielding cultivation and water-saving irrigation technologies,and boosting unit production potential; these improvements will eventually enhance regional grain supply capacity.关键词
