| 【目的】实施垦造水田项目是近年我国的耕地保护措施之一，有助于挖掘土地资源潜力、实现耕地质量提升、落实占补平衡政策。为了解垦造水田项目实施的效益，构建可推广可复制的模式，需要对垦造水田建设成效进行评价。【方法】通过 PSIR 模型构建垦造水田成效评价指标体系，基于 D 数理论改进的层次分析法和熵值法对指标进行综合赋权，运用 TOPSIS 法对吴川市 2014—2019 年的垦造水田进行评价比较和等级判定。【结果】从各子系统评价结果来看，压力指数最高的是梅菉街道、为 0.96，较低的是塘缀、黄坡、长岐、樟铺和振文镇，平均值为 0.09；状态指数较高的是海滨街道、振文镇和塘缀镇，平均值为 0.76，较低的是覃巴镇、塘尾街道、兰石镇、梅菉街道和浅水镇，平均值为 0.20；影响指数较高的是梅菉街道、大山江街道、塘尾街道和王村港镇，平均值为 0.73，较低的是振文、塘缀和黄坡镇，平均值为 0.19；响应指数较高的是兰石、吴阳和覃巴镇，平均值为 0.79，较低的是大山江街道、塘缀镇和塘尾镇，平均值为 0.17。吴川市 2014—2019 年垦造水田协调度较高的是海滨街道（1.58）、梅菉街道（1.51）和吴阳镇（1.46），而协调度较低的是振文镇（1.15）、塘缀镇（1.09）和黄坡镇（1.05）。垦造水田成效值与当地农业经济发展水平和农民人均收入呈负相关。【结论】吴川市 2014—2019 年垦造水田成效差异显著，呈现“西部成效较差，东部和南部成效较好”的特征，总体成效较好，对当地经济、生态和社会产生正影响。各地区应从薄弱环节出发，加强基础设施建设，促进水田集中连
片和规模化利用，以获得更好成效。 |

| 【Objective】The implementation of paddy field reclamation project is one of the arable land protection measures in China in recent years, which can exploit the potential of land resources, realize the improvement of arable land quality and implement the policy of occupancy and replenishment balance. In order to understand the benefits of implementation of paddy field reclamation project and build a propagable and replicable model, it is necessary to evaluate the effectiveness of paddy field reclamation construction.【Method】The evaluation index system of the effectiveness of paddy field reclamation was constructed by PSIR model, integrated weighting of indicators was conducted based on the improved hierarchical analysis and entropy method of D-number theory, and the TOPSIS method was applied to evaluate the comparison and grade determination of reclaimed paddy fields in Wuchuan City from 2014 to 2019.【Result】From the evaluation results of each subsystem, the pressure index of Meilu Street was highest (0.96), and that of the lower ones were Tangzhui Town, Huangpo Town, Changqi Town, Zhangpu Town and Zhenwen Town with a mean value of 0.09; the areas with higher status index were Haibin Street, Zhenwen Town and Tangzhui Town with a mean value of 0.76, and the areas with lower status index were Tanba Town, Tangwei Street, Lanshi Town, Meilu Street and Qianshui Town with a mean value of 0.2; the areas with higher impact index were Meilu Street, Dashanjiang Street, Tangwei Street and Wangcungang Town with a mean value of 0.73, and those with lower impact index were Zhenwen Town, Tangzhui Town and Huangpo Town with a mean value of 0.19. The higher response index was 0.79 in Lanshi Town, Wuyang Town and Tanba Town, and the lower was 0.17 in Dashanjiang Street, Tangzhui Town and Tangwei Town. The higher coordination of reclaimed paddy fields in Wuchuan City from 2014 to 2019 was found in Haibin Street (1.58), Meilu Street (1.51) and Wuyang Town (1.46), while the lower coordination was found in Zhenwen Town (1.15), Tangzhui Town (1.09) and Huangpo Town (1.05). The value of the effectiveness of reclaimed paddy fields was negatively correlated with the local level of agricultural economic development and the per capita income of farmers.【Conclusion】The effectiveness of reclaimed paddy fields in Wuchuan City from 2014 to 2019 varies significantly, showing a pattern of “poorer results in the west and better results in the east and south”. The overall results are good, with positive impacts on the local economy, ecology and society. Each region should start from the weak point, strengthen infrastructure construction and promote the centralized and large-scale use of paddy fields to obtain better results. |
