| 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. |
