中国西北农作制区耕地利用"显-隐性"形态耦合协调度研究
"Explicit-implicit"patterns coupling coordination degree of cropland utilization in the farming system of northwest China
摘要
Abstract
Studying cropland utilization patterns is crucial for achieving efficient cropland use and ensuring food security.This study explores the spatiotemporal evolution characteristics of the"explicit-implicit"patterns cou-pling coordination degree of cropland utilization in the farming regions of northwest China from 2010 to 2021.A comprehensive evaluation index system of cropland utilization patterns was constructed,and spatiotemporal sta-tistical methods were employed.The obstacle factors of cropland utilization were analyzed using the barrier de-gree decomposition model.The results showed that:(1)The explicit and implicit patterns of cropland utilization in northwest China's farming systems developed asynchronously,with significant regional differentiation and backward development.The coupling coordination degree between explicit and implicit patterns of cropland utili-zation remained low,exhibiting a pronounced polarization in each sub-region.(2)The intra-regional differences in the coupling coordination degree of"explicit-implicit"patterns of cropland utilization displayed a fluctuating downward trend,while the contribution rate of inter-regional differences gradually increased,becoming the main source of overall variation.Each sub-region demonstrated spatial convergence characteristics.(3)Cropland utili-zation is primarily constrained by factors such as cropland quantity structure,landscape characteristics,intensive level,and production function.To address these limitations,the study suggests improving the rational use of wa-ter resources,promoting the protection and development of suitable cultivated land,and alleviating the impact of obstacle factors.These measures aim to develop a suitable farming system and enhance the coupling development of"explicit-implicit"patterns of cropland utilization,providing a scientific reference for the sustainable develop-ment of cropland utilization in the farming systems of northwest China.关键词
