Boundary Determination of Lake-Type Wetland Park Based on GIS Multifactor Analysis

Abstract

One key carrier for wetland resource protection is wetland park, the main form of which includes lake-type wetland park. To determine the management and control boundary of lake-type wetland parks scientifically and reasonably is of great significance to the sustainable protection and utilization of wetland resources. From the perspective of landscape architecture, and landscape ecology, this paper studies the boundary determination of Changdang Lake National Wetland Park (the Park) based on satellite remote sensing information technology and GIS technology and in virtue of Analytic Hierarchy Process (AHP). In this study, 12 subindicators were selected from three levels including visual control, human geography, and ecological control. The weight of each indicator was determined by AHP, and then the influencing factors were transformed into graphic data by using GIS technology. Finally, the Park’s boundary was determined by factor superposition analysis based on the weight. The research shows that the newly defined management and control boundary are about 340 sq.km, which effectively integrates the human and natural ecological resources around the lake area, makes the development of the surrounding areas harmonious, ensures the integrity of the lake area ecosystem, and facilitates the sustainable development of wetland resources.

Analyzing the Worldwide Wetland Parks Research: A Spectral-Cluster Algorithm Latent Semantic Index Approach

“…Second, science popularization and education about wetland ecosystems can protect wetland ecosystems, to a certain extent, on account of public participation. These popularization and education efforts mainly rely on the natural and human resources in a wetland park [20] to protect a wetland based on the themes of ecological-function displays, popular-science knowledge, scientific research results, protection achievements, rationalutilization models, and cultural displays [4,21]. Science popularization and education raise public awareness about wetland protection and environmental protection by enabling the personal experience of a wetland in a wetland park [22].…”

“…Therefore, this study intends to evaluate recent investigations into this phenomenon. Researchers usually utilize experiments [31], surveys [42], case studies [17,26,33], big data analysis [43], geographic information system (GIS) technology [20], and the analytic hierarchy process [20,42] in research on wetland parks. Thus, the overarching aim of this study is to conduct a comprehensive and systematic analysis of studies on wetland parks from 1996 to 2022 using knowledge mappings to fill the research gap.…”

“…For example, Lin et al [82] studied cellulose-degrading bacteria, while Zhao et al [83] studied plant diversity and soil properties during different wetland restoration stages. Vegetation, soil, and hydrology are the most universally recognized and important features of wetland ecosystems [20]. Thus, research on water, soil, land resources, and CO 2 shall remain popular in the wetland parks literature in the future.…”
