Landscape Pattern Evolution Processes of Wetlands and Their Driving Factors in the Xiong’an New Area of China

Abstract

Wetland landscape patterns are the result of various ecological and hydrological processes. Based on the land use landscape types from 1980 to 2017, a transfer matrix, landscape pattern analysis index, and principal component analysis were used to analyze the landscape pattern evolution in the Xiong’an New Area of China, which has a large area with a lake and river wetlands. The results showed that the wetland area has changed greatly since 2000 and the beach land has decreased greatly, while the area of the lake and river wetlands has increased slightly. Beach land was the dominant landscape type of the wetland. The dominant degree of the wetland landscape showed a slightly decreasing trend, and the patches tended to be scattered. The shape complexity of the ponds was the lowest, while that of rivers was the highest. The fragmentation degree of the wetland patches increased, the proportion of landscape types tended to be equalized, and the landscape heterogeneity increased. The leading factors of the wetland landscape change can be summarized as socioeconomic, meteorological, and hydrological processes, with a cumulative contribution rate of 85.3%, among which socioeconomic development was the most important factor. The results have important guiding significance for the ecological restoration and management of wetlands in the Xiong’an New Area and other wetland ecosystems with rivers and lakes.

Spatial Coupling and Causal Effects between the Recreational Use of Ecological Land and Restoration: A Case Study of the Pearl River Delta Urban Agglomeration

“…With the rapid growth of the population and recreational demand in urban agglomeration areas, there may be a certain relationship between ecological restoration and recreational uses, but this impact has been overlooked compared to other perturbations [ 10 , 12 ]. The innovation of this study is to characterize the spatial distribution of ELR patterns, and to investigate the coupling mechanism of ELR and recreational use.…”

“…In many cities, the potential for human benefit (e.g., aesthetics, recreation) has become one of the driving forces for ELR [ 9 ]. In this context, an empirical examination of the spatial interaction between ELR and RUoEL in an urban agglomeration will provide insights into regionally environmental health planning to enhance the recreational well-being of residents [ 10 , 11 , 12 , 13 ].…”

A new framework combining hydrological connectivity metrics and morphological spatial pattern analysis for the hydrological connectivity evaluation of wetlands

“…The annual average precipitation and evaporation are 551.5 and 1369 mm, respectively (Z. Li, Sun, et al, 2021;Yang et al, 2021). Eighty percent of the precipitation occurs from June to September during the flood season (Y.…”

Evolution of Ecological Patterns of Poyang Lake Wetland Landscape over the Last One Hundred Years Based on Historical Topographic Maps and Landsat Images

“…Wetland affect the ecological environment through different mechanisms [26], among which the ecological environment effect of wetlands at the scale of landscape pattern is particularly important. The wetland landscape pattern reveals the ecological effects of different shapes and geometric spatial arrangements [27][28][29]. Such a landscape pattern not only is the result of the evolution of different processes of the ecological environment, but also has an impact on the later change process of the ecological environment [30].…”
