耕地利用绿色转型的时空格局及其驱动机制研究 ——以湖北省为例

研究目的：以湖北省为例，摸清耕地利用绿色转型的发展态势，揭示耕地利用绿色转型的时空格局及其成因，为耕地保护提供技术支撑。研究方法：熵值法、耦合协调度模型、时空地理加权回归模型。研究结果：（1）从时间上看，湖北省各城市耕地利用空间、功能、模式转型指数总体偏低但持续增长，在2015年前初步实现了耕地利用绿色转型，少部分地区尚未完成功能转型。（2）从空间上看，湖北省耕地利用绿色转型基本形成以东中部低山丘陵、平原为主的高值区及西部山地为核心的低值区并存的空间格局，高值区表现出“西进”态势。（3）湖北省耕地利用绿色转型的空间、功能、模式转型具有较强的耦合度，但失调现象日益凸显。（4）湖北省耕地利用绿色转型的时空演变是内外驱动因素共同作用的结果。研究结论：湖北省耕地利用绿色转型存在较大发展障碍，经济因素是当前耕地利用绿色转型的核心驱动因素。

Research on the Spatial-Temporal Pattern and Mechanisms of Green Transition of Farmland Use: A Case of Hubei Province

The purposes of this study are to explore the development trend of green transition of farmland use, to reveal the temporal and spatial patterns and causes of green transition of farmland use, and to provide technical support for farmland protection, taking Hubei Province as an example. The research methods include entropy approach, coupling coordination degree model as well as spatial-temporal geographic weighted regression. The research results show that: 1) from a temporal perspective, the spatial, functional and model transition indexes of green transition of farmland use in Hubei are generally low but continue to grow. The green transition of farmland use has been initially achieved before 2015, and a small number of areas have not yet completed the functional transition. 2) From a spatial perspective, the green transition of farmland use in Hubei Province forms a spatial pattern in which high-value areas dominated by low mountains and hills along with plains in the east and central regions and low-value areas taking western mountains as the core coexist. The high-value areas show a trend of the westward movement. 3) The space, function, and model transition of the green transition of farmland use in Hubei Province have a strong degree of coupling, but the imbalance phenomenon has become increasingly prominent. 4) The spatial-temporal evolution of the green transition of farmland use in Hubei Province results from the combined effect of internal and external driving factors. In conclusions, there are significant obstacles to the green transition of farmland use in Hubei Province, and economic factors are the core driving factors of the current green transition of farmland use.
