黄河流域耕地利用转型时空演变及其对粮食生产的影响
Spatial-temporal evolution of cultivated land use transition and its impact on grain production in the Yellow River Basin
摘要
Abstract
In order to explore the trend of cultivated land use transition and its impact on grain production,based on 115 prefecture-level cities in 9 provinces and autonomous regions of the Yellow River Basin,the entropy weight method,global spatial autocorrelation and spatial lag model were used to construct an index system of cultivated land use transition.The spatiotemporal pattern evolution of cultivated land use transition from 2000 to 2018 was analyzed by calculating the cultivated land use transition index,and the impact of cultivated land use transition on grain production was measured.The results showed that:1)The spatial distribution of the explicit transition index of cultivated land use in the Yellow River Basin displyed low in plain areas and high in mountainous areas patten.The spatial distribution of the implicit transition index is more related to local economic conditions.The explicit transition index,the implicit transition index and the integrated transition index all show a trend of first increasing and then decreasing.2)From 2000 to 2018,three types of transformation indices in the Yellow River Basin showed obvious spatial agglomeration,and the spatial agglomeration was gradually weakened.3)The explicit transition of cultivated land use inhibited grain production to a certain extent,and the implicit transition and comprehensive transition significantly promoted the increase of grain yield.The construction and improvement of infrastructure and mechanization level were the main reasons.In conclusion,this study can provide theoretical support and decision-making reference for the study of regional cultivated land use transition and ensuring grain production in the nine provinces and regions of the Yellow River Basin from the municipal scale.关键词
