摘要：

研究丹江口市耕地利用显性转型时空特征,为县域耕地可持续发展利用及合理开发提供科学依据。基于2009—2021年4期国土变更调查数据,构建土地利用转型矩阵、贡献率、耕地变化幅度、速度模型,从显性视角定性定量地揭示耕地数量形态及空间形态的时空变化特征,结果显示:2009—2021年丹江口市耕地利用转型数量形态变化较大,耕地净减少10 900.73 hm2,减少幅度达30.16%;分时段而言,丹江口市耕地数量转换在2017—2021年的转换面积最大,高达10 323.43 hm2;丹江口市各乡镇的耕地形态的变化幅度及速度在空间上差异显著,变化幅度集中于丹江口市西部周边的乡镇,而变化速度较大区域主要分布于丹江口市东部及北端区域。2009—2021年丹江口市耕地利用显性转型时空特征存在一定的规律性差异,对县域耕地利用转型识别和耕地利用的适度调整具有重大意义。

Abstract:

The temporal and spatial characteristics of the dominant transformation of cultivated land use in Danjiangkou City were studied to provide scientific basis for sustainable development and rational development of county cultivated land. Based on the land change survey data of four periods from 2009 to 2021, land use transition matrix, contribution rate, amplitude and velocity models of cultivated land change were constructed to reveal qualitative and quantitative spatio temporal change characteristics of cultivated land quantity form and spatial form from the dominant perspective. The results showed: From 2009 to 2021, the amount and form of cultivated land use transformation in Danjiangkou City changed greatly, with a net decrease of 10 900.73 hm2 (30.16%). In terms of time segments, the conversion area of cultivated land in Danjiangkou City during 2017-2021 was the largest, which was as high as 10 323.43 hm2. In Danjiangkou, the change amplitude and speed of cultivated land morphology were significantly different in space, and the change amplitude was concentrated in the villages and towns around the western part of Danjiangkou, while the areas with large change velocity were mainly distributed in the eastern and northern parts of Danjiangkou. The spatio temporal characteristics of the dominant transformation of cultivated land use in Danjiangkou City from 2009 to 2021 have some regular differences, which is of great significance for the identification of the transformation of cultivated land use in counties and the appropriate adjustment of cultivated land use.

Key words: cultivated land, dominant transformation, contribution rate, Danjiangkou City
