| 目的 屯昌县是海南省蜜柚发展的主要产区，基于高覆盖度的区域自动气象观测站点资料，开展屯昌县黄金蜜柚的精细化农业气候区划，将给屯昌县蜜柚的种植推广提供更加科学合理的参考依据。方法 文章利用2006—2017年屯昌县及周边39个区域气象站资料，结合年平均气温、≥10℃年有效积温、1月平均气温、极端最低气温4个黄金蜜柚气候区划指标，建立区划指标与经度、纬度和高程等因子的多元线性回归模型，小网格推算综合气候适宜性区划指标，绘制屯昌县黄金蜜柚农业气候区划图。结果 最适宜区主要分布在乌坡、南吕、屯城、新兴等乡镇；适宜区主要分布在南坤、西昌、枫木、坡心镇大部分地区；次适宜区和不适宜区主要分布在南坤镇和枫木镇交界的山区。结论 所构建的县级农业气候区划方法可为当前特色优势经济作物推广种植提供有效借鉴，区划结果对当地作物扩种、引种具有重要的指导意义。 |

| Abstract: |
| Tunchang county, the main cultivation area of Golden pomelo in Hainan province, is undergoing rapid development. Using the high coverage automatic weather station network in Hainan province, the precise agricultural climate zoning was assessed to provide more scientific and reasonable reference for the cultivation and extension of Golden pomelo in Tunchang. The data from 39 automatic weather stations in Tunchang and its surrounding areas from 2006 to 2017 were collected. Having checked the quality of the collected data, the data was jointly used with average temperature and annual effective accumulated temperature (≥10℃) to establish the average temperature in January and the extreme minimum temperature of four golden honey pomelo climate zoning indicatror. To do so, a multiple linear regression model of regionalization indices with factors such as longitude, latitude and elevation was employed. The comprehensive climatic suitability regionalization indices were calculated by grids, and the grading standard was established based on expert scoring method. The agricultural climate zoning map of Golden pomelo in Tunchang county was made. The results showed that: The optimum cultivation regions mainly included Wupo, Nanlu, Tuncheng, and Xinxing towns. The suitable cultivation regions included the most regions of Nankun, Xichang, Fengmu, and Poxin towns. The second-rate suitable cultivation regions were found to be the mountainous areas at the junction of Nankun town and Fengmu town. The unsuitable areas were mainly distributed in the mountainous areas at the junction of Nankun Town and Fengmu Town. It concludes that the method of precise agricultural climate zoning at county level can provide effective reference for the promotion and planting of characteristic dominant cash crops. The results of zoning will provide important and significant guidance on the expansion and introduction of local crops. |
