摘 要:本文研究了在全域土地整治背景下广东省低效耕地整治的潜力。基于VPM模型和1:100,000比例尺的国家土地利用/覆盖数据集(NLCD),我们估算了广东省高、中、低产农田的空间分布和生产力潜力提升。结果表明,广东省中、低产农田生产力分别为49,263.07×10^(4)tC/a和15,859.72×10^(4)tC/a,通过土地整治,中、低产农田的生产力分别可提升18.92%和24.05%。潜力提升最高的市包括湛江、肇庆、清远、茂名和广州,这些市的高潜力主要得益于广泛分布的中、低产农田面积和优越的自然条件。本研究为广东省的土地整治工作提供了科学依据,有助于提高土地利用效率和农业生产力。This article studies the remediation potential of low efficiency farmland in Guangdong Province under the background of global land consolidation.Based on the VPM model and the 1:100,000 scale national land use/cover dataset(NLCD),we estimated the spatial distribution and productivity potential improvement of high,medium,and low yield farmland in Guangdong Province.The results show that the productivity of medium and low yield farmland in Guangdong Province is 49,263.07×10^(4)tC/a and 15,859.72×10^(4)tC/a,respectively.Through land consolidation,the productivity of medium and low yield farmland can be increased by 18.92%and 24.05%,respectively.The cities with the highest potential for improvement include Zhanjiang,Zhaoqing,Qingyuan,Maoming,and Guangzhou,whose high potential is mainly due to the wide distribution of medium and low yield farmland and the superior natural conditions.This study provides a scientific basis for land consolidation work in Guangdong Province,and is helpful to improve the land-use efficiency and the agricultural productivity.
