云南山区宜耕未利用地开发适宜性评价与潜力分区
为更好地引导云南山区宜耕未利用地的开发,该文以云南省典型的山区县―弥渡县为例,将GIS(geographical information system,GIS)空间分析技术、层次分析法(analytical hierarchy process,AHP)及特尔菲法(Delphi)相结合,分别构建宜耕未利用地开发适宜性评价模型、新增耕地指数及补充耕地潜力模型、宜耕未利用地开发潜力分区评价模型,对云南山区宜耕未利用地开发适宜性与潜力分区进行了分析。结果表明,研究区宜耕未利用地开发适宜性分为4个等级:最适宜、中等适宜、勉强适宜、不适宜,面积分别为71.21、1177.39、1681.00和62.00h...

Summary: | 为更好地引导云南山区宜耕未利用地的开发,该文以云南省典型的山区县―弥渡县为例,将GIS(geographical information system,GIS)空间分析技术、层次分析法(analytical hierarchy process,AHP)及特尔菲法(Delphi)相结合,分别构建宜耕未利用地开发适宜性评价模型、新增耕地指数及补充耕地潜力模型、宜耕未利用地开发潜力分区评价模型,对云南山区宜耕未利用地开发适宜性与潜力分区进行了分析。结果表明,研究区宜耕未利用地开发适宜性分为4个等级:最适宜、中等适宜、勉强适宜、不适宜,面积分别为71.21、1177.39、1681.00和62.00hm2,分别占研究区总面积的2.38%、39.36%、56.19%、2.07%。研究区宜耕未利用地实际开发潜力为1248.60hm2,预计新增耕地面积977.45hm2。潜力分区结果表明,研究区可划分为5个潜力区和1个非潜力区。其中,Ⅰ级潜力区实际开发潜力164.97hm2,可新增耕地144.21hm2;Ⅱ级潜力区实际开发潜力53.38hm2,可新增耕地46.66hm2;Ⅲ级潜力区实际开发潜力210.64hm2,可新增耕地164.01hm2;Ⅳ级潜力区实际开发潜力773.93hm2,可新增耕地590.11hm2;Ⅴ级潜力区实际开发潜力45.68hm2,可新增耕地32.46hm2。研究结果的应用表明,该种方法得出的适宜性评价结果、新增耕地测算结果及潜力分区结果与当地实际较为吻合。 |

Faculty of Surveying and Mapping, Kunming Metallurgy College, Kunming 650033, China) Unused land is the major reserve resource of cultivated land in China. But the quality of the unused land is generally relatively poor in many provinces. Because of the poor quality and complexity of explotation for the unused land, the difficulty of exploitation is often relatively large. This is especially true in the mountainous areas of Yunnan province, where there is an undulating terrain, and severe cutting or tearing action. Therefore, geoscience factors show significan |
