摘要：

为运用遥感手段掌握云南省甘蔗种植区域空间分布特征,评估甘蔗种植优势度,以云南甘蔗种植区为研究对象,采用Landsat8-OLI为数据源,结合地面调查结果,通过极大似然法提取甘蔗种植区域空间分布及面积,利用比较优势指数法、使用甘蔗遥感面积评估各区甘蔗种植优势度。2014—2016年遥感影像监测显示,云南省甘蔗种植面积约为24.12万hm 2,主要集中分布在该省西南以及南部地区的主要河流沿线地带,临沧、德宏、保山、普洱、文山等区域的甘蔗面积约占全省的88%。比较优势指数法评估结果显示,临沧、德宏、普洱、保山、西双版纳的甘蔗规模优势指数分别为4.76、5.25、2.07、1.53、3.26,为云南甘蔗种植的优势区域;文山、玉溪、红河、大理等地区规模优势指数均小于1,种植优势不明显。研究结果可为云南甘蔗种植空间布局与优化调整提供参考。

Abstract:

To obtain the spatial distribution information of sugarcane planting area in Yunnan and evaluate the dominance of sugarcane planting, the spatial distribution and acreage of sugarcane in Yunnan were estimated by using Landsat8 Operational Land Imager (OLI) images, corresponding data of in-situ survey and the method of maximum likelihood. Based on the remote sensing acreage, the dominance of sugarcane in each region was evaluated by using the method of comparative advantage index. According to the study, the average acreage of sugarcane in the study area between 2014 and 2016 was approximately 241233 hm 2, mainly distributed along major valleys in the southwest and south of Yunnan. About 88% of sugarcane acreage in Yunnan was from five regions as Licang, Dehong, Baoshan, Pu’er and Wenshan. The scale advantage index of Lincang, Dehong, Pu’er, Baoshan and Xishuangbanna was 4.76, 5.25, 2.07, 1.53 and 3.26, respectively, and these regions were considered as the dominant area for sugarcane planting. The scale advantage index of Wenshan, Yuxi, Honghe and Dali was lower than 1, indicating no obvious planting advantage. This study could provide references for the spatial layout and optimization adjustment of sugarcane planting in Yunnan.
