The stability and suitability of reclaiming dryland soil into paddy soil in Suixi County were analyzed,and a selecting construction method was provided based on the coupling coordination degree model and hotspot analytical skill.The results showed that Suixi County had more potential to reclaim dryland soil into paddy soil.The high and medium suitable area were 81.08％ of the total cultivated area,mostly were distributed in eastern villages and towns.The stability and suitability had distinct spatial distribution.The high stable areas were located in Beipo Town and Guangqian Company and some other towns.Yanggan Town,Beipo Town,Jiepao Town and Guangqian Company were easier to be reclaimed,which accounted for 41.04％ of the total remodel area.Those places had abundant natural resources and well-constructed infrastructures,and enjoyed a perfect distance of the public traffic highways.Finally,most hotspots that were suitable and stable for reclaiming were located in Yanggan Town,Beipo Town,Jiepao Town and Guangqian Company,which had more priority in reclaiming process.The total constructional area for land reclaiming was 462.75 hm2 in Suixi County during the 13th Five-year Plan.This research provided methodological reference for further scientific selection and reclaiming dryland soil into paddy soil distribution.%从分析遂溪县“旱改水”建设适宜性和空间稳定性人手,提出了基于耦合协调度模型和冷热点分析方法的“旱改水”建设项目遴选布局方法.结果表明,遂溪县开展“旱改水”建设潜力较大,其中高、中适宜区占耕地总面积的81.08％,主要分布在中东部乡镇;稳定性与适宜性的空间分布差异显著,高稳定性地块主要集中在北坡镇和广前公司,在其余乡镇也有分布;容易改造地块占耕地总面积的41.04％,主要分布在北坡镇、界炮镇、杨柑镇和广前公司等,该类耕地自然禀赋较好、基础设施完备,并且与城镇、交通干线有一定距离,建设占用的可能性较小;“旱改水”建设适宜性和空间稳定性耦合协调的热点区主要分布在杨柑镇、北坡镇、界炮镇和广前公司等中部乡镇,是“旱改水”项目布局的优先选择区域;结合研究区实际,确定遂溪县“十三五”期间“旱改水”建设区总面积462.75 hm2.该研究为科学遴选、布局“旱改水”建设项目提供了方法借鉴.
