| 中文摘要: |
| 【目的】量化茂名市县域蔬菜生产布局与产地集中的变迁及发展趋势。【方法】采用专业化、集聚化程度指数，对茂名市县域 1998—2018 年蔬菜产地集中状况进行量化分析，探究茂名市蔬菜生产地域格局变化规律。对茂名不同时期蔬菜产地集中程度进行度量，进一步分析不同阶段茂名蔬菜产地布局的特点。【结果】茂名蔬菜播种面积和产量集中度均较广东省总体水平高，主要集中在电白区、化州市、高州市，但蔬菜单位面积产量超过茂名市平均水平的只有高州市，而电白区和化州市蔬菜单位面积产量处于全市平均值以下。通过产值对茂名各地区进行专业化程度分析，蔬菜种植面积最小的茂南区专业化水平最高，其区位熵维持在2.0 左右，远超其他地区，约为信宜市的 2.5 倍；电白区专业化水平排第 2 位；而化州市与高州市作为蔬菜主产区，其区位熵较低，地区相对专业化指数均小于 0。【结论】通过对专业化与聚集化程度指标进行综合分析，茂名市的蔬菜产业集中度高，部分区县专业化水平也不低，但集中度与其专业化水平不匹配。 |

| 【Objective】The study was carried out to quantify the change and development trend of vegetable production layout and production area aggregation in various counties of Maoming Municipality.【Method】The degree of specialization and aggregation indexes were adopted to quantitatively analyze the concentration of vegetable production areas in various counties of Maoming Municipality from 1998 to 2018, and explore the change law of regional pattern of vegetable
production in Maoming Municipality. The aggregation degree of vegetable production areas in Maoming in different periods was measured to further analyze the characteristics of vegetable production areas distribution in different periods.【Result】The aggregation degree of sown area and yield of vegetable in Maoming was relatively higher than the overall level in Guangdong Province, which was mainly concentrated in the Dianbai District, Huazhou City, Gaozhou City, however, only yield per unit area of Gaozhou City was higher than the average of Maoming Municipality, while that of Dianbai District and Huazhou City was lower than the average in the whole city. Based on the analysis of specialization degree of various regions in Maoming through the output values, Maonan District with the smallest vegetable planting area had the highest specialization level, with its location quotient maintaining at about 2.0, far more than other regions in Maoming, about 2.5 times that of Xinyi City. The specialization degree of Dianbai District ranked the second. As major vegetable producing areas, Huazhou City of Gaozhou City had lower location quotient, with the relative specialization index less than 0.【Conclusion】Through the comprehensive analysis of the above indicators, it can be seen that the aggregation degree of the vegetable industry in Maoming is high and the specialization degree in some areas is not low, however, the specialization degree does not match with the aggregation degree. |
