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 462.75hm2 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.
