开展耕地细碎化多维评价并评估治理适宜性,可为耕地细碎化分区整治提供参考。本研究以新疆昌吉州为研究区域,以行政村作为基本研究单元,从耕地立地条件、耕作便利程度、景观格局差异3个方面构建评价指标体系,使用熵值法确定指标权重,利用三维魔方图解方法划定整治分区。结果表明:昌吉州耕地立地条件属性总体偏低,由南向北呈现低-高-低的分异格局,其中3级区占比最多,为35.52%;耕作便利程度属性总体较低,呈现西高东低、南北低中间高的分异格局,其中2级区占比最多,为41.66%;耕地细碎化程度整体较高且空间分异明显,呈现东高西低、南北高中间低的分异格局,其中1级区、3级区和4级区占比均在32%以上,细碎化最严重的区域集中在吉木萨尔县、奇台县和木垒哈萨克自治县南部的山前丘陵区域;治理适宜性3级区和4级区占比累计达到62.64%,耕地细碎化治理适宜性整体较高。耕地细碎化是地形地貌、资源禀赋、经济社会发展等自然和人为因素共同作用的结果,基于昌吉州耕地细碎化不同属性特征的层次组合特点,划分集约利用区65个、归并提升区330个、资源优化区211个、综合整治区371个,据此提出不同分区土地整治方向及建议。 |

Conducting a multidimensional evaluation of fragmented farmland and assessing its suitability for remediation, this study serves as a reference for targeted interventions in fragmented farmland. Taking Changji Prefecture, Xinjiang as the study area and administrative villages as the basic research units, we constructed an evaluation index system based on three aspects:farmland site conditions, convenience of cultivation, and landscape pattern differences. We determined the weight of each index using the entropy method and delineate the management zones using a three-dimensional cube diagram. Overall, the farmland site conditions in Changji Prefecture were relatively low, showing a low-high-low pattern from south to north, with the highest proportion in the third-level zone at 35.52%. The convenience of cultivation was generally low, with a west high-east low and north south low-middle high pattern, with the highest proportion in the second-level zone at 41.66%. Farmland fragmentation was overall high and spatially distinct, with an east high-west low and north south high-middle low pattern. The most severe fragmentation occured in the mountainous areas in the southern part of Jimusaer County, Qitai County, and Mulei Kazakh Autonomous County. The suitability for management was relatively high, with the cumulative proportion of the third and fourth-level zones reaching 62.64%. Farmland fragmentation was the result of natural and human factors such as topography, resource endowment, and socio-economic development. Based on the hierarchical combination characteristics of different attributes of farmland fragmentation in Changji Prefecture, we divided it into 65 intensive utilization zones, 330 merge and upgrade zones, 211 resource optimization zones, and 371 comprehensive improvement zones. We proposed different land management directions and recommendations for each zone. |
