摘要
The domestic demands of coastal tourism have increased rapidly in recent years, stimulating the development and utilization of coastal areas. At the same time, unreasonable development patterns bring a series of resource and environment problems that require scientific evaluation of coastal tourism value to guide regional sustainable development. This paper constructs a coastline tourism value assessment model with three dimensions: coastline natural attributes, tourism development factors, and location factors. Combined with the particularity of coastal tourism, indicators such as coastline type, sea water quality, tourism infrastructure, land use, and scenic spots are selected. The model focuses on the Pearl River Delta to quantitatively assess the tourism value and its spatial distribution on the mainland and island coastlines. The results show that in the Pearl River Delta, the advantageous coastline for tourism accounts for 25.50%, the middle value coastline for 40.67%, and the low and lowest value coastlines for 30.52% and 3.31%, respectively. From the perspective of spatial distribution, the tourism value of the eastern part of the Pearl River Delta is higher than the western part. The highest tourism value of mainland coastline is concentrated in Huizhou Xunliao Bay, Shenzhen Daya Bay, Dapeng Bay, and Shenzhen Bay. These areas have excellent water quality, long sandy coastlines, superior natural conditions, and better tourism infrastructure. The lowest tourism value of mainland coastline is concentrated in the west of Huangmaohai, mainly because most of its coastline is artificial and estuarine and the location advantage is insufficient. The tourism value of the central part of the Pearl River estuary is medium. There is a big spatial difference in the tourism value of island shoreline. The highest value is concentrated in Sanmen Island, Xizhou Island, Jixin Island, Dalajia Island in Daya Bay, Neilingding Island in the Pearl River Estuary, and the north of Shang Xiachuan Island; the lowest value is concentrated in Wanshan Island and Dangan Island in Zhuhai. On the county scale, the tourism value of the Pearl River Delta coastal area has a significant spatial autocorrelation. The coastlines with higher comprehensive value are concentrated in Bao’an District, Longgang District, Futian District, and Yantian District of Shenzhen; the coastlines with lower value are concentrated in Jinwan District and Doumen District of Zhuhai. This research has made some exploration in the scientific evaluation of the tourism value of the coastal zone and enriched the theory of tourism resources development of the coastal zone. It also has reference value for clarifying the development orientation of different coastal areas and regions, giving full play to the advantages of tourism resources, making reasonable development strategies, and providing policy support for the development of the coastal region tourism in the Pearl River Delta.
