| 摘 要： | 各地在将耕地划定为基本农田时,主要考虑完成保护数量的任务,而对地区之间资源禀赋的差异则考虑不够。利用GIS空间分析技术,借鉴土地适宜性研究的思路,提出依据土地适宜性指数和土地利用现状划定基本农田的思路。以江苏省泗阳县为例,依上述划定方法,入选基本农田的耕地面积为577.5km2,占全县耕地面积的84.8%。县域北部、南部区域的耕地因适宜性高而入选比例较高,城镇周边、道路两侧的耕地因适宜性低且开发需求高,入选比例相对较低。这样的基本农田划定模式,有助于发挥不同地区的资源禀赋优势,强化划入基本农田部分的耕地保护力度,可达到经济发展与耕地保护相协调的效果。

| Abstract: | When cultivated land is designated as basic farmland,the goals of land protection plan are mainly considered,while regional differences in resource endowments are usually neglected.With the help of spatial analysis technologies and previous studies on land suitability evaluation,this paper points out that the designation of basic farmland should be based on land suitability index and present situation of land use.By taking Siyang County as an example,basic farmland designated using the new method is 577.5 km2,about 84.8% of total cultivated land.The proportion of basic farmland in the north and the south of Siyang County is relatively high because its land suitability index is high.The proportion of basic farmland near Siyang County and main roads is relatively low because of high construction land demands.The result indicates that we should take regional differences in resource endowments into consideration while converting cultivated land into basic farmland,so as to coordinate the contradiction between land protection and economic growth. |
