- 摘要:
- 从中观尺度探讨耕地景观细碎化演变特征及其机制,可反映区域人地关系变化,为耕地细碎化优化路径提供科学依据,推动耕地保护工作长足发展。选取赣东典型山地丘陵区万年县为研究区,基于GIS技术、景观格局指数、熵权法和地理探测器等研究方法对耕地细碎化演变与驱动因素进行了分析。结果表明:(1)万年县2009—2018年耕地细碎化程度明显加剧,耕地细碎化面积指数、形状指数均显著提高,分布指数呈现下降趋势;(2)万年县耕地细碎化主要驱动因素为高程、乡镇人口密度、距农村居民点距离以及坡度,各探测因子对耕地细碎化的影响呈相互增强或非线性增强效应;(3)综合发展型、工业贸易型、生态旅游型以及农业生产型乡镇主要驱动因子分异明显。因此,耕地细碎化优化工作应基于资源禀赋进行土地用途优化配置,基于社会功能分区进行乡镇发展政策牵引。
- Abstract:
- Discussing the evolution characteristics and mechanism of cultivated land landscape fragmentation from the mesoscale can reflect the changes in the regional human-land relationship, provide a scientific basis for the optimized path of cultivated land fragmentation, and promote the development of cultivated land protection. Wannian County, a typical hilly area in eastern Jiangxi, was selected as the research area. Based on the research methods of GIS technology, landscape pattern index, entropy weight method, and geographic detector, the evolution and driving factors of cultivated land fragmentation were analyzed. The result showed that:(1)in Wannian County, the degree of cultivated land fragmentation increased significantly from 2009 to 2018, the spatial agglomeration effect of cultivated land fragmentation decreased, the area index and shape index of cultivated land fragmentation increased significantly, and the distribution index showed a downward trend;(2)the main driving factors of cultivated land fragmentation in Wannian County are elevation, township population density, distance from rural settlements and slope, and the detection factors have mutually or non-linearly enhanced effects on cultivated land fragmentation;(3)the main driving factors of townships with different functional types are various. The optimization of arable land fragmentation and optimization in different regions should optimize the allocation of land use based on resource endowments. Townships with different development orientations have different main drivers of cultivated land fragmentation based on social function zoning for the development of township development policies. The remediation of cultivated land fragmentation should optimize the allocation of land use based on resource endowment, and formulate township development policies based on social function zoning.
