摘  要：
研究耕地后备资源开发适宜性,测算其丰度值,明确开发模式能够为耕地后备资源合理可持续利用提供科学依据。以山西省襄汾县为研究区,通过构建模糊综合评价模型,对襄汾县生态安全、自然适宜和经济可行3个方面进行开发适宜性评价;在适宜性评价的基础上,通过计算新增耕地系数和新增耕地面积占比,构建耕地后备资源丰度测算模型,并以丰度值为依据,运用ArcGIS空间分析功能,将襄汾县开发模式进行分区研究。结果表明,襄汾县无高等适宜后备资源;较高等适宜面积为2 187.775 4 hm~2;中等适宜面积为11 511.268 1 hm~2;勉强适宜面积为3 782.169 9 hm~2;不适宜开发面积为543.683 5 hm~2。襄汾县耕地后备资源开发分为4种模式,优先开发模式总规模为3 685.640 2 hm~2;重点开发模式总规模为3 413.028 4 hm~2;适度开发模式总规模为5 073.909 4 hm~2;先保护后开发模式总规模为5 852.318 8 hm~2。在耕地后备资源开发过程中,应因地制宜,对不同区域采取差别化开发,以实现耕地后备资源的可持续利用。

摘  要：
It is important for us to provide a scientific basis and sustainable use of cultivated land reserve resources to study the suitability development of cultivated land reserve resources, measure the abundance value of cultivated land reserve resources, and clarify development model. This paper takes Xiangfen county of Shanxi province as the research area, and constructs a fuzzy comprehensive evaluation model to evaluate the development suitability of the three aspects of ecological security, natural suitability and economic feasibility. Based on the principle of maximum membership degree, the fuzzy vector list is used. On the basis of suitability evaluation, the abundance calculation model of cultivated land reserve resources is constructed by calculating the ratio of newly cultivated land and new cultivated land. Using Arc GIS spatial analysis function, it can distinguish Xiangfen into diffierent development models. The research shows that there is no suitable reserve resources in Xiangfen county, the higher suitable area is 2 187.775 4 hm~2, the moderately suitable area is 11 511.268 1 hm~2, the barely suitable area is 3 782.169 9 hm~2, the unsuitable development area is 543.683 5 hm~2. The development of reserve resources for cultivated land in Xiangfen county is divided into four modes: the total scale of the priority development model is 3 685.640 2 hm~2, the total scale of the key development model is 3 413.028 4 hm~2, the total scale of the moderate development model is 5 073.909 4 hm~2, the total scale of the development model after protection is 5 852.318 8 hm~2. Therefore, in the development of cultivated land reserve resources, it is necessary to adopt different developments in different areas to achieve sustainable use of cultivated land reserve resources.
