新型城镇化背景下耕地多功能价值测算及动态变化研究——以河北省定州市为例

Calculation and Dynamic Change Analysis on Multi-functional Value of Cultivated Land under the Background of New Urbanization:A Case Study of Dingzhou City

以河北省定州市为研究区,在对耕地功能分类基础上,采用收益还原法、成果参照法、替代法、分解求和法,利用耕地、人口、经济等相关统计数据对定州市2000-2013年耕地价值进行测算,并分析其动态变化特征。结果表明,耕地价值在2000-2013年呈逐年增长趋势,单位面积耕地价值年均增长率达6.28%,耕地总价值年均增长率达6.74%。在耕地价值构成中,生产功能价值所占比例基本保持在60%左右,社会功能价值在35%左右,生态功能价值基本在5%左右,三者所占比例相对稳定。受社会经济发展、人民生活水平和物价水平等因素影响,耕地社会价值增长幅度较大;受化肥、农药投入、经济发展水平等影响,生态价值有下降趋势。

Taking Dingzhou city as the study area,on the basis of the function classification of cultivated land,this paper used the income reduction method,results of reference method,substitution method and summation method to calculate the value of cultivated land and analyze its dynamic characteristics during 2000 to 2013.The date of cultivated land,population,economy and other relevant statistical data were used.The results showed that the value of cultivated land was increasing year by year from 2000 to 2013,the average annual growth rate of per unit cultivated land value was 6.28%,and the average annual growth rate of cultivated land value was 6.74%.In the value composition of arable land,the proportion of production value was maintained at about 60%,the social value was about 35%,the ecological value was about 5%,and the proportion of the three was relatively stable.The factors that affected the development of social economy,people’s living standard and the price level,the social value of cultivated land increased greatly.Affected by the fertilizer,pesticide input,economic development level,the ecological value had a downward trend.
