Analysis on the Temporal and Spatial Differentiation and Influencing Factors of Non-grain Conversion of Farmland in the Economically Developed Areas
摘要
Abstract
[Objection/Meaning]The study aimed to explore the temporal and spatial evolution laws of non-grain conversion of farmland at the plot scale in the economically developed areas and its influencing factors,so as to provide reference for the formulation of farmland protection policies.[Methods/Procedures]Firstly,based on the interpretation of remote sensing images,the types and degrees of non-grain conversion of farmland in Hangzhou City in 2010,2015 and 2020 were identified at the plot scale.Furthermore,with the help of the Geographically and Temporally Weighted Regression model(GTWR),the influencing mechanism of non-grain conversion of farmland was explored.[Results/Conclusions]The study found that:(1)From 2010 to 2015,the non-grain conversion rate of farmland in Hangzhou City increased from 26.05％to 31.42％,and then decreased to 15.83％from 2015 to 2020.The spatial distribution imbalance intensified.(2)During the research period,the area of pond aquaculture decreased significantly,while the area of vegetable production continued to increase.(3)The original quality of farmland aggravated the expansion of non-grain conversion of farmland.On the contrary,the geographical conditions were the key factors to inhibit the spread of this trend.The impact of the accessibility of agricultural landscapes on the non-grain conversion of farmland changed from negative to positive.(4)The influencing factors of non-grain conversion of farmland mainly played a role in the urban fringe areas,and the spatial heterogeneity was high.Based on the above conclusions,the attention should be paid to the temporal and spatial evolution and the type trends of non-grain conversion of farmland,the differences in factors such as the original quality and geographical conditions should be considered,and the management and control of urban fringe areas should be strengthened,so as to balance the urban development and food security.关键词
