摘要
按照"面积不减少,质量有提高,布局总体稳定"的方针调整基本农田布局,是新一轮土地利用总体规划的主要内容之一。本文以稳定现状基本农田布局的思路为基础,研究基本农田布局调整方法。综合考虑耕地质量、区位条件、坡度及连片性等因素,构建耕地入选基本农田潜力评价指标体系;以江西省高安市为例,采用综合评价法进行潜力评价,借助GIS技术获取评价指标值,依据评价结果调整基本农田布局;比较调整前后的基本农田,以农用地分等利用等指数和集中连片性为检验内容,调整后基本农田中优质耕地比重由38.51%提高到45.35%,集中连片耕地比重由27.81%提高到30.56%。研究优化了当地的基本农田布局,对县域土地利用总体规划的基本农田调整工作具有一定借鉴意义。
To adjust the basic farmland layout according to ＂area not decreased, quality increased, layout stabilized＂ principle is a big part in the new land use planning. This paper, based on the ideas of stabilizing the current basic farmland layout, studies the ways to adjust the basic farmland layout. An index system which covers farmland quality, locality, slope and integrity is established to evaluate the potentials. Based on a case study on Gao＇an city, Jiangxi province, a comprehensive method is used to evaluate the potentials via GIS, which is employed to adjust the basic farmland layout. After adjustment, the excellent farmland percentage rises form 38. 35% to 45. 35% , integrity percentage from 27.81% to 30.56%. This study optimizes the basic farmland layout, offering references in adjusting the basic farmland layout in a county-level land use planning.
