不同尺度下耕地利用转型对经济发展的影响

The influence of cultivated land use transformation on economic development at different scales

基于功能形态、空间形态两种视角对耕地利用转型进行测度,描述2000—2018年鄂西贫困地区耕地利用转型特征,并以区域、县域两种研究尺度从不同角度解释耕地利用转型对经济发展的影响规律。结果表明,耕地利用转型可以看作耕地利用形态在时间序列上的断点型变化;耕地利用转型对地区经济发展存在一定的促进作用,但伴随经济发展,影响作用在逐步降低;耕地利用转型对鄂西地区经济发展存在促进作用的同时,也存在一定的限制作用。

The transformation of cultivated land use from the perspective of functional form and spatial form was measured,the characteristics of the transformation of cultivated land use in poor areas of western Hubei from 2000 to 2018 were described,and the law of the influence of cultivated land use transformation on economic development from different perspectives in two research scales of regional and county was explained.The results showed that the transformation of cultivated land use could be regarded as a breakpoint change of cultivated land use pattern in time series;the transformation of cultivated land use had a certain promoting effect on regional economic development,but with economic development,the influence gradually decreased;the transformation of cultivated land use not only promoted the economic development of western Hubei,but also restricted the economic development of western Hubei.
