常州地区耕地利用空间分异及影响因素分析
|
摘要
[目的]通过分析常州地区耕地总面积时空格局进行分析,并利用耕地区位指数模型测算各子区域耕地面积的空间差异,并在此基础上,分析常州地区耕地利用的影响因素。[方法]文章运用地理综合分析方法分析1985—2015年常州地区耕地利用空间分异;选取人口、社会、经济、环境、科技5方面共12个指标,分析常州地区耕地空间分异的影响因素。[结果]从常州地区耕地面积时间变化来看,1985—2015年常州地区耕地总面积整体呈现出递减趋势;从常州地区耕地面积空间变化来看,总体来说,常州南部地区(溧阳区)为耕地密集区,北部(新北、钟楼、天宁、武进)为耕地稀疏区;从影响因素的效用来看,经济因素的影响效用大,尤其是人均GDP和地均GDP的比重,而社会因素的影响较小,尤其是房屋竣工面积、公路里程。[结论]总体而言,受区域经济发展影响,常州地区耕地面积呈下降趋势,但近年来下降幅度已基本得到控制。
By analyzing the spatial and temporal pattern of the total cultivated land area in Changzhou,the spatial difference of cultivated land area in each sub-area was calculated by using the cultivated area index model,and on this basis,the influencing factors of cultivated land use in Changzhou were analyzed. The geographical comprehensive analysis method was used to analyze the spatial differentiation of cultivated land use in Changzhou from 1985 to2015,and 12 indicators including population,society,economy,environment and science and technology were selected to analyze the influencing factors of cultivated land spatial differentiation in Changzhou. According to the temporal change of cultivated land area in Changzhou,the total cultivated land area in Changzhou showed a decreasing trend from 1985 to 2015. From the spatial change of cultivated land area in Changzhou,in general,the southern area of Changzhou( Liyang area) was the intensive cultivated land area,while the northern area( Xinbei,Zhonglou,Tianning,Wujin) was the sparse cultivated land area. From the perspective of the effects of influencing factors,the effects of economic factors were large,especially the proportion of GDP per capita and per unit area GDP,while the influence of social factors was small,especially the floor space of buildings completed and highway mileage. Overall,affected by regional economic development,the area of cultivated land in Changzhou has shown a downward trend,but the decline has been basically controlled in recent years.
