Hangzhou Bay is an important estuarial coastal wetland, which offers a large number of land and ecological resources. It plays a significant role in the sustainable development of resources, environment and economy. In this paper, based on the remote sensing images in 1996, 2005 and 2013, we extracted the coastal wetland data and analyzed the wetland landscape pattern of the Hangzhou Bay in the past 20 years. The results show that: (1) the area of coastal wetland is heading downwards in the recent decades. Paddy field and the coastal wetland diminish greatly. (2) the single dynamic degree of wetland of the Hangzhou Bay displays that paddy fields and coastal wetlands are shrinking, but lakes, reservoirs and ponds are constantly expanding. (3) the wetland landscape pattern index shows that total patch area of the coastal wetland and paddy fields have gradually diminished. The Shannon diversity index, the Shannon evenness index as well as the landscape separation index of the coastal wetlands in the Hangzhou Bay increase steadily. The landscape pattern in the study area has shown a trend of high fragmentation, dominance decreases, but some dominant landscape still exist in this region. (4) Urbanization and natural factors lead to the reduction of wetland area. Besides the pressure of population is a major threat to the wetland. The study will provide scientific basis for long-term planning for this region.

This article explores regional Buddhist monasteries in Tang Dynasty (618–907 CE) China, including their arrangement, functions, and sources for their study. Specifically, as a case study, it considers the reconstruction of the Kaiyuan monastery 開元寺 in Sizhou 泗州 (present-day Jiangsu Province) with reference to the works of three prominent state officials and scholars: Bai Juyi 白居易 (772–846), Li Ao 李翱 (772–841), and Han Yu 韓愈 (768–824). The writings of these literati allow us to trace the various phases of the monastery’s reconstruction, fundraising activities, and the network of individuals who participated in the project. We learn that the rebuilt multi-compound complex not only provided living areas for masses of pilgrims, traders, and workers but also functioned as a barrier that protected the populations of Sizhou and neighboring prefectures from flooding. Moreover, when viewed from a broader perspective, the renovation of the Kaiyuan monastery demonstrates that Buddhist construction projects played a pivotal role in the social and economic development of Tang China’s major metropolises as well as its regions.
