Solid waste disposal and management have become a global problem, which is particularly tricky in China with its large population rapid urbanization. This study focused on the status of multi-source solid as well park some typical cities China. Firstly, main technical methods for were summarized follows: landfill, incineration, anaerobic digestion aerobic compost. Secondly, network analysis method was applied to seek an optimized management. Thirdly, demonstration parks analyzed their respective operating modes strategies synergistic development terms resources, environment economy explore sustainable potential Guangdong–Hong Kong–Macao mode. The results showed that collaborative recycling are important (especially megacities) achieve resource conservation environmental protection. NIMBY effect pollution risks caused by decentralized construction could be reduced through circular industrial parks. Advanced technologies national policy small–medium cities, large–medium megacities systematically so self-operating mode Finally, reasonable suggestions, such sharing, saving cycling propaganda education, green low-carbon solutions put forward parks, effectively resolving contradiction between economic protection help urban development.

Suitability of Site Selection for Mountain Railway Engineering Spoil Disposal Areas from a Multi-Scenario Perspective

Buildings, Год журнала: 2024, Номер 14(4), С. 1184 - 1184

Опубликована: Апрель 22, 2024

The current approach to selecting sites for abandoned spoil areas primarily relies on qualitative methods, often overlooking the impact of policy factors decision-making. Traditional single-site selection strategies may not be flexible enough accommodate evolving external demands. Addressing this challenge is crucial ensuring site both scientifically sound and policy-compliant. This research integrates various analytical including principal component analysis, complex network theory, CRITIC method, ordered weighted averaging thoroughly evaluate influencing selection. Utilizing geographic information system (GIS) technology, study simulates different scenarios, such as construction cost, social ecological concerns, natural security, spatial accessibility, a comprehensive balance approach. It specifically analyzes suitability segment Chongqing ZW Railway under these conditions. Based actual situation in local area, six potential suitable were screened with help field investigation. can offer methodological framework theoretical guidance optimally locating mountain railway engineering waste disposal sites. In addition, methodology presented adapted development change scenarios.

Contribution of Atmospheric Factors in Predicting Sea Surface Temperature in the East China Sea Using the Random Forest and SA-ConvLSTM Model

Atmosphere, Год журнала: 2024, Номер 15(6), С. 670 - 670

Опубликована: Май 31, 2024

Atmospheric forcings are significant physical factors that influence the variation of sea surface temperature (SST) and often used as essential input variables for ocean numerical models. However, their contribution to prediction SST based on machine-learning methods still needs be tested. This study presents a model in East China Sea (ECS) using two methods: Random Forest SA-ConvLSTM algorithms. According feature importance scores correlation coefficients R, 2 m air longwave radiation were selected most important key atmospheric can affect performance methods. Four datasets constructed SA-ConvLSTM: SST-only, SST-T2m, SST-LWR, SST-T2m-LWR. Using SST-T2m skill improved by about 9.9% 9.43% RMSE 8.97% 8.21% MAE, respectively. SST-T2m-LWR dataset, model’s 10.75% 9.06% MAE. The represent ECS well, but with highest AE summer. findings presented requires much more exploration future studies.

The importance of principal component analysis for environmental biodiagnostics of Donbass

E3S Web of Conferences, Год журнала: 2024, Номер 555, С. 01007 - 01007

Опубликована: Янв. 1, 2024

The ecological situation in the Central Donbas remains tense today and requires timely diagnosis of state ecosystems. Major causes environmental Donbass are high level industrialization (mining, metallurgical, mining chemical industries), urbanization, agricultural technologies, landscape transformation warfare from 2014 to present. With all variety biological methods obtaining large numerical information, importance mathematical approaches is particular significance. Using example principal component analysis, a method for visualizing data assessing transformed ecotopes has been tested. An attempt made reconstruct some missing list characteristics. values probability reliability have established. This allows more accurate information monitoring environment region. Principal analysis complements available cartographic materials, highlights most significant processes considering general degradation ecosystems (by indicator plants Bryum argenteum Hedw., Ceratodon purpureus (Hedw.) Brid, Amblystegium subtile Schimp., Centaurea diffusa Lam., Cichorium intybus L., Tripleurospermum inodorum (L.) Sch. Bip. et al.). cause effect relationships peculiarities grouped order further restore integrity functionality historical geographical environment.

How Do Driving Factors Affect the Ecological Restoration Degree in Different Basins? A Case Study of Six River Basins in Yunnan, China

Land, Год журнала: 2024, Номер 13(12), С. 2091 - 2091

Опубликована: Дек. 4, 2024

Ecological space provides human beings with the material resources and living environment needed for life; it is basis survival development, ecological restoration directly related to sustainable development of society. As an important security barrier in China, six river basins Yunnan Province affects surrounding provinces neighboring countries. At present, there still a lack research on differences between basins. Therefore, we assessed spatiotemporal degree terms ecosystem patterns, quality, services from 2000 2019 explored their influencing factors The results showed following: ① differed changes patterns over 20-year period, share settlement ecosystems increasing most pronounced occurred Nu River Basin. There were also transformation priorities In addition this, among four selected indicators, fractional vegetation cover, net primary productivity, soil conservation increased, but water retention exhibited stable deteriorating trend. ② Province’s as whole relatively state. no significant improvement or deterioration region. best Pearl Basin, trend gradual stabilization improvement, worst state deterioration. ③ that influence Restoration Index (ERI) are mean annual precipitation change rate, precipitation, temperature, engineering, border index. rate was factor basins, while index ERI future, measures should take into account regional differences, strengthen governmental supervision, emphasize impact promote balanced whole.

Опубликована: Янв. 1, 2023

Resumo A promulgação da Política Nacional de Resíduos Sólidos foi um marco ambiental decisivo no âmbito das gestões municipais resíduos sólidos sustentáveis e qualidade. Assim, o objetivo do trabalho analisar os efeitos PNRS nos municípios populosos mineiros através aplicação Análise dos Componentes Principais (ACP). Esta análise realizada por meio software RStudio “R v. 3.5.1” após selecionar variáveis estudo acordo com a aderência ao tema disponibilidade dados Sistema Informação sobre Saneamento. Além constatar-se que ACP é adequada para tal dois componentes são suficientes representar mais 70% variabilidade dados, certificou-se estão relacionados objetivos princípios PNRS. Portanto, concluiu-se efeito manejo RSU nestes positivo, mas não suficiente considerando idade Lei urgência olhar sistêmico alcançar Como evidência desta visão reducionista, menciona-se enfoque dado apenas coleta seletiva, quando demais etapas descentralizar deveriam ser consideradas mesma importância.
