摘要:

目的 结合广东省“十三五”时期农用地整理重点工程，揭示广东省农用地整理潜力和分布特征，划分重点区域、布局重点工程并确定建设规模，以期为省域尺度的土地整治重点工程布局提供参考。方法 文章运用自然间断点分级法，分别对广东省高标准农田建设、垦造水田和基塘整治进行潜力分级，利用数据统计和潜力空间分析，确定高标准农田建设、垦造水田和基塘整治的工程布局和规模。结果 广东省高标准农田建设和垦造水田的二、三级潜力区占比超过80%，全省大部分县（市、区）的整理潜力规模较小，聚集程度低；基塘整治潜力区全部位于珠三角地区，一级潜力区面积占比达60%，且聚集程度高。基本农田建设示范工程宜布局在惠州市、江门市、肇庆市等14个地级市的16个县（市、区），规模为32.32万hm²；宜于惠州市、江门市、潮州市等9个地级市的20个县（市、区）布局5.99万hm²的垦造水田集中区示范工程；基塘整治和文化提升重点工程宜布局在佛山市和中山市，规模为0.60万hm²。结论 在农用地整治潜力和空间分析、重点区域划定等基础上，布局高标准农田建设、垦造水田和基塘整治重点工程空间和规模，具有可行性和合理性，可应用到省级土地整治规划工作中。

Abstract:

The paper aims to reveal the potentiality and distribution characteristics of agricultural land consolidation, divide key areas, deploy key projects and determine construction scale combined with the key projects of agricultural land consolidation in Guangdong province during the “13th Five-Year Plan” period, so as to provide reference for the layout of key land consolidation projects at the provincial scale. Natural discontinuity classification method was employed to analyze the potential of high-standard agricultural land construction, reclamation of paddy fields and field-ponds remediation in Guangdong province, and data statistics and potential spatial analysis was used to determine the project layout and scale of high-standard agricultural land construction, reclamation of paddy fields and field-ponds remediation. The results were listed as follows. The secondary and tertiary potential areas of high-standard agricultural land construction and paddy field reclamation in Guangdong accounted for more than 80%, and most of the counties (cities and districts) in the province had a small scale of consolidation and with a low degree of aggregation. The field-pond potential improvement areas were all located in the Pearl River Delta region, with the first-level potential area accounting for 60% of the area and with a high degree of aggregation. The demonstration project of basic farmland construction involved 16 counties (cities, districts) of 14 prefecture-level cities, including Huizhou city, Jiangmen city, and Zhaoqing city, with a scale of 323 200 hm²; the demonstration project of reclaiming paddy field concentration areas involved Huizhou city and Jiangmen city 20 counties (cities, districts) of 9 prefecture-level cities, including Chaozhou city, with a scale of 59 900 hm²; key projects for rectification and cultural improvement of the field-pond involved Zhongshan and Foshan city, with a scale of 6 000 hm². In summary, the space and scale of key projects for high-standard agricultural land construction, paddy field cultivation and field-ponds remediation could be laid out based on the potential analysis, spatial analysis and key area delimitation. The method of this study can be applied to the provincial land consolidation planning for its feasibility and rationality.
