Urban Lake Scenic Protected Area Zoning Based on Ecological Sensitivity Analysis and Remote Sensing: A Case Study of Chaohu Lake Basin, China

Abstract

The protection of urban lakes is important for the construction and development of the city and the eco-environment. Affected by urban expansion, most urban lake scenic areas have suffered from a reduction in area and ecological degradation. Protecting and restoring urban lake scenic areas has been a hot topic among the public. Given this background information, we analyzed the ecological problems and contradictions from the perspective of landscape ecology. This study evaluated the landscape pattern and ecological sensitivity in the Chaohu Lake Basin, China. The proposed method was based on the analytical hierarchy process (AHP) and geographical information system (GIS). The results showed that the ecological sensitivity map was divided into four sensitivity levels consisting of level 1, level 3, level 5, and level 7, which represent 65%, 27%, 5%, and 2% of the study area. It was found that highly sensitive areas existed primarily in the highlands, where the natural conditions were poorer than in other areas and human activities have been developing rapidly. Additionally, the medium sensitive levels occurred in the low lands, probably in response to agricultural practices. Based on our results, three ecological zones were proposed, which require different protection and utilization solutions in order to restore the local ecological environment in terms of sustainable development.

Differential Analysis of Island Mountain Plant Community Characteristics: Ecological Sensitivity Perspectives

“…The impact of anthropogenic interference on the ecological environment is predominantly evident in the land use type. Drawing on previous studies [5,7,32] and taking into account the ecological conditions of Pingtan Island, a set of ecological sensitivity evaluation factors for Pingtan Island was initially formulated, and expert consultation was conducted. Ultimately, eight factors, namely, elevation, slope, slope direction, vegetation coverage, soil texture, water environment, wind environment, and land use type, were selected to construct the ecological sensitivity evaluation system for Pingtan Island.…”

“…The construction of a suitable evaluation system, tailored to the characteristics of the study area, stands as a particularly pivotal aspect of an ecological sensitivity assessment. In the extant literature, factors such as elevation, soil composition, water quality, and vegetation coverage are commonly considered in ecological sensitivity evaluations [5][6][7]. It is noteworthy that the habitat characteristics of sea islands, owing to their unique geographical locations, can be significantly influenced by the wind environment.…”

A Review of Village Ecosystem Structure and Stability: Implications for the Karst Desertification Control

“…In KDC areas, due to the disparate natural factors and degree of human disturbance, the villages in the region are also located in different landform types and Karst desertification levels [120], which makes the ecosystem structure of each village different, and then affects the degree of function [121]. The restoration ability of disturbed village ecosystem stability in Karst region and non-Karst region is quite different [122]. The influence of village ecosystem structure on stability is heterogeneous, so it is very important to construct an evaluation index system for the stability of Karst village ecosystem.…”

Evaluation of Ecological Sensitivity and Spatial Correlation Analysis of Landscape Patterns in Sanjiangyuan National Park

“…This analytical framework finds wide application across various domains, encompassing nature reserve planning [10], wetland conservation and development planning [11][12][13], and urban environmental assessment [14,15]. Subsequently, scholars have directed attention towards integrating ecological sensitivity into tourism planning and development [16,17]. For instance, Fu et al devised an ecological assessment framework for the Xandu Mountain Scenic Area in Jinyun County, Lishui City, Zhejiang Province, China.…”
