粤西丘陵区旱改水潜力评价方法研究--以广东省新兴县为例

目前,广东省可用于占补平衡的耕地储备指标数量充足,但解决"占优补优、占水田补水田"的困境及落实"十三五"占补平衡任务的压力非常大。该研究以广东省新兴县为例,运用多因素综合评价法和特尔斐法建立符合粤西丘陵区旱改水潜力评价的指标体系,进而分析旱改水适宜性潜力等级和规模潜力等级,揭示了粤西丘陵区旱地改造水田的可行性,并为全省日后开展旱改水工作提供参考。

Study on Evaluation Methods of Potentiality of Changing from Dry Land to Paddy Field in Hilly Areas of Western Guangdong-A Case Study of Xinxing County in Guangdong Province

At present, the quantity of cultivated land in Guangdong Province is abundant, but the pressure of solving the dilemma of “Occupy high quality and supplement the quality, and Occupy paddy field and supplement paddy field”and implementing the balance task in the “13th Five-year Plan”period is very big.In this paper, taking Xinxing County of Guangdong Province as an example, the evaluationindex system of po-tentiality of changing from dry land to paddy field in hilly areas of western Guangdong was established by multi-factor comprehensive evaluation method and Delphi method, and the suitability potential level and scale potential level of changing from dry land to paddy field were analyzed to reveal the feasibility of changing from dry land to paddy field in hilly areas of western Guangdong , thereby providing a reference for the imple-mentation of changing from dry land to paddy field in future.
