【目的】对广西崇左市江州区甘蔗种植适宜性进行评价,为甘蔗产业布局的调整提供科学依据。【方法】基于广西崇左市江州区2016年甘蔗作物地块矢量数据,选取土壤、地形、气象和经济4个因子共16个评价指标,利用层次分析法及加权指数和模型评价江州区甘蔗种植适宜性,根据评价结果采用GIS技术将甘蔗种植划分为最适宜、适宜、次适宜和不适宜区域。【结果】将甘蔗种植最适宜和适宜面积与部分“双高”基地(高产高糖糖料蔗基地)面积进行比较,结果显示二者差异较小,评价结果与实际情况基本吻合。崇左市江州区濑湍镇甘蔗种植最适宜区面积为3799.80 ha,占最适宜区总面积的36.90%;崇左市新和镇甘蔗种植不适宜区面积共177.85 ha,占不适宜区总面积的28.84%。【结论】为了科学、合理及有效地利用土地资源,提高甘蔗产量,建议新增“双高”基地,可调整广西崇左市江州区甘蔗布局区域向濑湍镇、罗白乡、太平街道、驮卢镇和左州镇等地发展。
【Objective】 The objective of this study was to evaluate the suitability of sugarcane planting in Jiangzhou District of Chongzuo City, Guangxi Province, and to provide a scientific basis for adjusting the industrial layout of sugarcane. 【Method】 Based on the 2016 vector data of sugarcane crop in Jiangzhou District, Chongzuo City, Guangxi Autonomous Region, a total of 16 indicators including soil, topography, meteorology and economy were selected and evaluated by using AHP and weighted index and model Sugarcane planting suitability, according to the evaluation results using GIS technology will be divided into the most suitable sugarcane cultivation, suitable, sub-suitable and not suitable for the region. 【Result】 The results showed that the most suitable and suitable area for sugarcane planting was compared with the area of some “Shuang Gao” base (base of sugarcane with high yield and high sugar content). The results showed that there was little difference between the two and the evaluation results were in good agreement with the actual situation. The optimum area for sugarcane planting in Setu Town, Jiangzhou District, Chongzuo City was 3799.80 ha, accounting for 36.90% of the total area of the most suitable area. The inappropriate area of sugarcane planting in Xinhe Town, Chongzuo City was 177.85 ha, accounting for the total unsuitable area 28.84% of the area. 【Conclusion】 In order to scientifically, reasonably and effectively use the land resources and increase the output of sugarcane, it is suggested to add “Shuang Gao ” base to adjust the layout of sugarcane in Jiangzhou District, Chongzuo, Guangxi.
