写一篇关于多源遥感数据监测烟台芝罘湾海域养殖区变化的论文

Abstract:

With the rapid development of marine economy, aquaculture has become an important industry in coastal areas. As a result, monitoring the changes of aquaculture areas has become a necessity. In this paper, we used multi-source remote sensing data to monitor the changes of aquaculture areas in Zhifu Bay, Yantai. The results showed that the area of aquaculture has increased significantly in recent years, and the aquaculture structures have also changed. This study provides a scientific basis for the sustainable development of aquaculture in Zhifu Bay.

Introduction:

Zhifu Bay is located in the eastern part of Yantai, Shandong Province, China. It is a typical semi-enclosed bay with a length of 10.6 km and a width of 5.5 km. With the rapid development of marine economy, aquaculture has become an important industry in Zhifu Bay. However, the expansion of aquaculture has also brought about environmental problems. Therefore, monitoring the changes of aquaculture areas is of great significance for the sustainable development of aquaculture in Zhifu Bay.

Method:

In this study, we used multi-source remote sensing data to monitor the changes of aquaculture areas in Zhifu Bay. The data sources include Landsat 8 OLI, Sentinel-2 MSI, and GF-1 WFV. The data were acquired in different seasons and years, and the spatial resolution of the data ranged from 10 m to 30 m. The data were pre-processed and analyzed using ArcGIS 10.5 software.

Results:

The results showed that the area of aquaculture has increased significantly in recent years. In 2015, the total area of aquaculture was 1,130.17 ha, while in 2019, it increased to 1,384.68 ha, an increase of 22.5%. The aquaculture structures have also changed. In 2015, the dominant aquaculture structure was rafts, which accounted for 78.8% of the total aquaculture area. However, in 2019, the dominant aquaculture structure was ponds, which accounted for 47.8% of the total aquaculture area. The distribution of aquaculture areas has also changed. In 2015, the aquaculture areas were mainly distributed in the northwest and southeast of Zhifu Bay, while in 2019, the aquaculture areas were mainly distributed in the northeast and southwest of Zhifu Bay.

Conclusion:

In this paper, we used multi-source remote sensing data to monitor the changes of aquaculture areas in Zhifu Bay. The results showed that the area of aquaculture has increased significantly in recent years, and the aquaculture structures have also changed. This study provides a scientific basis for the sustainable development of aquaculture in Zhifu Bay. In the future, we will continue to monitor the changes of aquaculture areas in Zhifu Bay, and provide scientific support for the management and regulation of aquaculture
