基于面向对象分割的耕地集中连片经营分布提取及其 影响因素研究——以大同市云州区四乡镇为例.

To explore how to promote the centralized, contiguous, large-scale management of cultivated land, the cultivated land patches of the third land survey carried out by the Chinese government this decade, Google Earth high-resolution remote sensing images, and questionnaire data from field research were used to study Xiping Town, Beijiazao Town, Duzhuang Town and Dangliuzhuang Town in Yunzhou District, Datong City of China. The object-oriented segmentation method was used to segment the cultivated land patches and obtain cultivated land management patches. The landscape pattern software Fragstats 4.2, SPSS statistical software, and the geographical detector model were used to analyze the spatial distribution of centralized contiguous management of cultivated land in the four towns of Yunzhou District as well as its main influencing factors. The results show that the four towns of Yunzhou District were primarily located in the hinterland of Datong Basin with flat terrain, and the aggregation index was >80. The overall distribution of cultivated land patches was relatively concentrated, and the cultivated land with concentrated contiguous status of Ⅲ and Ⅳ was larger than those of status Ⅰ and Ⅱ, accounting for 58.63%. In addition, the explanatory power of influencing factors on the centralized contiguous management of cultivated land in descending order was：the transfer rate of cultivated land, the proportion of daylily area, per capita income, the proportion of people with higher education, the proportion of agricultural farmers, the number of cooperatives, and the source of income; the differentiation determination index (q) values of these factors were >0.1. Moreover, the interaction effect exhibited both nonlinear and mutual enhancement, in which the interaction of the planting area of daylily with number of cooperatives was prominent, highlighting the essential role of the planting area of daylily in the centralized contiguous management of cultivated land. The effective transfer of cultivated land, the cultivation of daylily, and the establishment of cooperatives have promoted the centralized contiguous management of cultivated land.
