Ecological conservation, remediation and construction for building an ecological civilization in China: concepts for ecological activity

This paper explains and discusses the concepts of ecological conservation and construction in China in three parts. The first part provides a brief description of the historical background of ecological activities in China and their major achievements in the past. The second part is a comprehensive review of various types of ecological control activity aimed at the improvement of natural and artificially established ecosystems at the landscape,regional(watershed) and higher levels. The scope of and differences between some ecological terms used in China such as ecological protection, conservation, remediation(rehabilitation), restoration as well as the reestablishment of new ecosystems are elaborated. The review suggests that the term "ecological conservation and construction"should be used to embrace all types of ecological control activity in China. Finally, five guidelines are proposed for promoting the implementation of ecological conservation and construction in China based on the two important governmental documents related to the development of ecological civilization in China.

Landscape Design outside National Maritime Museum

With the development of urban construction and improvement of living standard, modern people have had higher requirements on culture. National Maritime Museum collects and displays maritime culture and civilization of China, it is a signifi cant cultural facility in New Binhai District of Tianjin. The museum shows us the splendid picture of yel ow terrestrial civilization and blue maritime civilization over the past 2,000 years in China. Landscape design outside the exhibition hall of the museum has the integration of culture and museum as the starting point, and makes brand-new explorations in landscape humanistic care and landscape designs of green buildings.

Utilizing interpretable stacking ensemble learning and NSGA-Ⅲ for the prediction and optimisation of building photo-thermal environment and energy consumption

This study develops an approach consisting of a stacking model integrated with a multi-objective optimisation algorithm aimed at predicting and optimising the ecological performance of buildings.The integrated model consists of five base models and a meta-model,which significantly improves the prediction performance.Specifically,the R2 value was improved by 9.19% and the error metrics MAE,MSE,MAPE,and CVRMSE were reduced by 69.47%,79.88%,67.32%,and 57.02%,respectively,compared to the single prediction model.According to the research on interpretable machine learning,adding the SHAP value gives us a deeper understanding of the impact of each architectural design parameter on the performance.In the multi-objective optimisation part,we used the NSGA-Ⅲ algorithm to successfully improve the energy efficiency,daylight utilisation and thermal comfort of the building.Specifically,the optimal design solution reduces the energy use intensity by 31.6 kWh/m^(2),improves the useful daylight index by 39%,and modulated the thermal comfort index,resulting in a decrement of 0.69℃ for the summer season and an enhancement of 0.64℃ for the winter season,respectively.Overall,this study provides building designers and decision makers with a tool to make better design decisions at an early stage to achieve a better combination of energy efficiency,daylight utilisation and thermal comfort optimisation in an integrated manner,providing an important support for achieving sustainable building design.
