摘要:
[目的]文章以云南省陆良县为研究区,通过2013年4月到2017年3月6景Landsat 8 OLI影像提取该地区规模化设施种植区域空间分布信息,分析该县设施种植区域的空间特征和面积时序变化,为设施农业发展调控和优化提供参考信息。[方法]使用OLI全色波段影像和多光谱影像融合,得到15m分辨率的融合图像; 使用融合图像7、5、3波段组合的RGB假彩色图像进行目视解译,提取设施种植区域信息。[结果]获取该县2013—2017年共6期设施种植区域空间信息。[结论]遥感监测显示:(1)该地区设施大棚包括种植蔬菜瓜果的光温棚和种植三七的遮阳棚; 光温棚主要分布于湖积平原区,遮阳棚主要分布于北部、西部及南部环盆地的山坡地区; (2)陆良县设施种植区域总面积保持增加趋势,但不同类型大棚的变化趋势不同; 光温棚面积自2013年4月到2017年3月持续增加; 遮阳棚面积则出现大幅增长和大幅减少的现象。

Abstract:
Changes of facility planting region is a hot issue of the present agricultural land change science in China. However, it was few researches about the monitoring of facility planting region using remote sensing technology recently. Yunnan province has become an important vegetable base in China due to the development of facility agriculture in recent years. In order to provide geospatial information for the regulation and optimization of facility agriculture in Luliang county, Yunnan province, six Landsat 8 OLI images since 2013 to 2017 were collected and processed. Base on the Gram Schmidt method, fusion images of the 15m resolution were obtained from panchromatic images and multi spectral images. Using the method of artificial visual interpretation, the spatial information of two types facility planting of the last five years were acquired base on six fusion images. According to the results of monitoring, the facility planting of Luliang county included sun light greenhouse and polyethylene awning. Sun light greenhouse were mainly used for vegetable planting, polyethylene awning were mainly used for pseudo ginseng planting. The distribution of different facilities was related to the environmental requirements of crops. Sun light greenhouse was mainly distributed in cultivated land of the lacustrine plain, and the awning was mainly distributed in the slopes of the northern, western and southern around the lacustrine plain. The area of facility planting in Luliang county was generally increasing since 2013 to 2017. The area of sun light greenhouse had kept growing since 2013. The trend of the area of awning was a phenomenon of significant increase and decrease from 2013 to 2017.
