    摘要:

    從分析遂溪縣“旱改水”建設(shè)適宜性和空間穩(wěn)定性入手,提出了基于耦合協(xié)調(diào)度模型和冷熱點(diǎn)分析方法的“旱改水”建設(shè)項(xiàng)目遴選布局方法。結(jié)果表明,遂溪縣開展“旱改水”建設(shè)潛力較大,其中高、中適宜區(qū)占耕地總面積的81.08%,主要分布在中東部鄉(xiāng)鎮(zhèn);穩(wěn)定性與適宜性的空間分布差異顯著,高穩(wěn)定性地塊主要集中在北坡鎮(zhèn)和廣前公司,在其余鄉(xiāng)鎮(zhèn)也有分布;容易改造地塊占耕地總面積的41.04%,主要分布在北坡鎮(zhèn)、界炮鎮(zhèn)、楊柑鎮(zhèn)和廣前公司等,該類耕地自然稟賦較好、基礎(chǔ)設(shè)施完備,并且與城鎮(zhèn)、交通干線有一定距離,建設(shè)占用的可能性較?。弧昂蹈乃苯ㄔO(shè)適宜性和空間穩(wěn)定性耦合協(xié)調(diào)的熱點(diǎn)區(qū)主要分布在楊柑鎮(zhèn)、北坡鎮(zhèn)、界炮鎮(zhèn)和廣前公司等中部鄉(xiāng)鎮(zhèn),是“旱改水”項(xiàng)目布局的優(yōu)先選擇區(qū)域;結(jié)合研究區(qū)實(shí)際,確定遂溪縣“十三五”期間“旱改水”建設(shè)區(qū)總面積462.75hm2。該研究為科學(xué)遴選、布局“旱改水”建設(shè)項(xiàng)目提供了方法借鑒。

    Abstract:

    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.
