黄河流域耕地压力时空演变特征研究
Study on the spatio-temporal evolution characteristics of cultivated land pressure in the Yellow River Basin
摘要
Abstract
To promote high-quality development of the Yellow River Basin,it is necessary to enhance the protection of cultivated land and food security within the basin.Based on the modified cropland pressure index model with standard cropland coefficients,this paper investigated the spatio-temporal evolution characteristics of cultivated land resources and cultivated land pressure from the per-spective of the Yellow River Basin and urban areas from 2005 to 2021.The results showed that:①The value of cropland pressure index fluctuated and decreased in the Yellow River basin.The spatial distribution pattern showed a basic trend of"stable overall layout and local changes".The center of gravity of pressure showed an oscillating pattern of east-west changes,with the overall migration to the northwest.②The heterogeneity of cultivated land pressure in each city was obvious,the degree of dispersion had increased,and the phe-nomenon of polarization of spatial layout was obvious.The time series of cultivated land pressure in each municipality showed an invert-ed"N"or"fluctuating"type distribution.The spatial pattern of cultivated land pressure in each municipality was characterized by the clustering of pressure in the middle and upper reaches.③The pressure on cultivated land in the upper and middle reaches of the Yellow River was too heavy,and the pressure in the lower reaches of the Yellow River continued to grow,all of which needed to attract the at-tention of the governmental departments,in order to increase the area of cultivated land and grain yields through policy adjustments,sci-entific and technological inputs,and other measures,so as to realize high-efficiency and modernized agriculture.关键词
