Ecological Remediation

Due to the recent excessive pursuit of rapid economic development in China, the cultural heritage resources have been gradually destroyed. This paper proposes cultural recovery and ecological remediation patterns, and adopts virtual reality (VR) technology to evaluate the visual aesthetic effect of the restored landscape. The results show that: (1) the average vegetation coverage increased, providing data support for remediation design evaluation; and (2) the fixation counts and average saccade counts of the subjects increased after the remediation design, indicating that the restored cultural landscape reduced visual fatigue and provided a better visual aesthetic experience. Furthermore, the comparative analysis of the quality of the water environment shows that the remediation design project improved the ecological environment quality of the relics area. The results of this study will contribute to rural revitalization in minority areas in southwest China.

The Social

The value of home gardens has become more apparent among tenants forced into isolation in difficult and uncertain times arising since the COVID-19 pandemic started at the beginning of 2020. While gardens make a significant contribution to the social and ecological environment of cities, most studies have focused on public green spaces. Investigating householder preferences for gardens during and after the mandatory lockdown period in the UAE is required. The main objective of this study is to analyze the householder’s attitude, preferences, and willingness to have home gardens during the pandemic and after. The data were collected via an online survey of randomly selected respondents. A logistic econometrical model was utilized to analyze the factors affecting respondent preferences regarding having a garden. According to the results, the probability of having a garden increases among respondents who produce some crops, have attained Msc/PhD. level, a backyard, and a larger space to cultivate. It decreases among those who are married, find it hard to take care of a garden, and face a weed problem. In conclusions, it is highly recommended for householders to have home gardens, which can provide a quality lifestyle and enhance leisure time during the pandemic and after.

The Relationship

In order to explore the relationship between water quality indicators and the cross-section,this paper applied principal component analysis to evaluate comprehensively the water quality monitoring sections of the Liaohe River. The results showed that the water quality of the Liaohe River Tieling and Shenyang segments belonged to the inferior class V water. In this paper, water quality assessment and water environment quality grading used respectively two ways that were not and setting up a virtual cross-section to avoid the classification of water environment quality impacting on the relationship between water quality indicators and quality monitoring sections. Principal component score applied two and three-dimensional graphic display,made expression of the water pollution situation more intuitive.
