Assessing Ecological Quality Based on Remote Sensing Images in Wugong Mountain

Abstract

With the sustained development of China's economy, tourism has become an important part of promoting economic development. Consequently, it is urgent to explore how to solve the conflict of increased resource consumption and environmental protection brought about by the prosperity of tourism economy so as to realize the coordinated development of economic development and ecological environment. Compared with the traditional monitoring methods, such as manual monitoring, station monitoring, and so on, remote sensing technology has the advantages of a wide monitoring range, strong comprehensiveness, and less human resource consumption, which can enable the real-time dynamic monitoring and evaluation of vegetation coverage and ecological quality (EQ;Arjasakusuma et al., 2020;Musinsky et al., 2018).Wugong Mountain (WGM) is a popular scenic spot with its landscape, ecological, and cultural diversities. Existing research, the research on WGM mainly focuses on mountain meadow (Q. and geology (X. F. Li et al., 2018), while little is studied on the vegetation coverage and EQ of WGM. Therefore, it is of a great significance to monitor and evaluate the vegetation coverage and EQ of WGM in a certain period. It cannot only clarify its spatial distribution characteristics and changing trends, but also help realize the dynamic monitoring of the ecological environment of WGM.Vegetation is the main type of surface cover in Wugong Mountain Scenic Area (WGM). Fractional Vegetation Cover (FVC), a common indicator of vegetation monitoring using remote sensing, is used to measure the characteristic distribution of surface vegetation (Zhao et al., 2016), reflecting climate change (Tong et al., 2016) and mountain ecosystem (García-Llamas et al., 2019). In the study of mountain ecosystems, the influence of mountain topography on the formation and changes of vegetation should be taken under consideration. The most common way to reveal the relationship between vegetation and topography, is studying the topographic characteristics of vegetation coverage (Niederheiser et al., 2018). For instance, Zhang et al. (2018) demonstrated the distribution pattern of vegetation coverage in WGM meadow correlates with the terrain factors (including elevation, slope, and aspect) based on the dimidiate pixel model. By studying the correlation between vegetation

Assessment Of Remote Sensing Approach For Urban Ecological Quality Evaluation In Pekanbaru City, Riau Province Indonesia

“…Between 2018 and 2021, the correlation coefficient between SAVI and NDMI exceeds 90%, indicating\ a strong relationship between them. This finding is consistent with the results of (Y. G. Gao et al 2022), who found that the average value of the Ecological Index increased in the Wugong Mountain region from 2015 to 2019, with the greenness and humidity indices positively impacting ecological quality. Meanwhile, \NDBI correlates negatively with NDMI but positively with NDSI, while NDSI has a negative correlation with NDMI.…”

“…The evaluation of ecological quality aims to assess the state of the environment and the ecosystem health. It aids in understanding the impact of various factors on vegetation coverage and the overall ecological conditions (Y. G. Gao et al 2022). In this study, the Remote Sensing Ecological Index (RSEI) is used to assess the ecological quality in Pekanbaru City, Riau province, Indonesia.…”

Evaluation of soil and water conservation function in the Wugong mountain meadow based on the comprehensive index method

“…A popular scenic spot, Wugong Mountain offers landscape, ecological, and cultural diversity. Existing research, the research on Wugong Mountain mainly focuses on mountain meadows ( Liu et al., 2018 ), geology ( Li et al., 2018 ), soil quality ( Li et al., 2017 , 2020 ), effects of tourism ( Rana et al., 2022 ) and ecological quality ( Gao et al., 2022 ). In contrast, little is studied on the meadow soil's hydro-physical characteristics and water conservation function of Wugong Mountain.…”

Evaluation of Remote Sensing Ecological Index Based on Soil and Water Conservation on the Effectiveness of Management of Abandoned Mine Landscaping Transformation

“…The RSEI has more comprehensive and social criteria applicability, which makes up for the deficiency of the traditional evaluation method of using a normalized vegetation index to evaluate ecological quality. Existing studies based on the RSEI have conducted a large number of studies on cities and urban clusters [ 27 , 28 , 29 ], nature reserves [ 30 , 31 , 32 ], soil erosion areas [ 33 , 34 ], and mines [ 35 ].…”
