| 摘 要： | 农业适宜性评价是当前国土空间开发适宜性评价及空间规划的重要内容。本文以中山市为例,利用卫星遥感影像、DEM、统计年鉴、相关政府部门政务公开数据以及大数据爬虫数据等众源数据,采用层次分析法(AHP)和熵权法(EWM)两种方法分别对各指标数据计算权重,得到两份农业空间适宜性评价结果。在此基础上通过集成学习法得到一份最终农业空间适宜性评价结果。结果表明,中山市农业高、较高适宜区主要分布在黄埔镇东北部、三角镇、民众镇、港口镇、南朗镇东部、坦洲镇西南部、板芙镇西北部和沙溪镇北部;低适宜区主要分布在五桂山街道、南朗镇西北部、火炬开发区、东区街道、板芙镇东部和坦洲镇北部;其余为中适宜区。

| Abstract: | Agricultural suitability evaluation is an important content of land space development suitability evaluation and spatial planning.In this paper,taking Zhongshan City as an example,using multi-source data such as satellite remote sensing image,DEM,statistical yearbook,government affairs open data of relevant government departments and big data crawler data,AHP and EWM are used to calculate the weight of each index data respectively,and two agricultural spatial suitability evaluation results are obtained.On this basis,a final evaluation result of agricultural spatial suitability is obtained by integrated learning method.The results show that the suitable areas for high and high agricultural level are mainly distributed in the northeast of Huangpu town,triangle town,Minzu Town,Gangkou Town,the east of Nanlang Town,the southwest of Tanzhou Town,the northwest of Banfu Town and the north of Shaxi Town.The low suitable area is mainly distributed in Wuguishan Street,the northwest of Nanlang Town,Torch Development Zone,East District Street,east of Banfu town and north of Tanzhou Town.The rest are suitable areas. |
