With the rapid development of urbanization,landscape architecture has become an indispensable component of daily life.In order to achieve better landscape effects and protect the ecological environment,landscape ecology theory can be integrated into landscape planning to carry out disciplinary crossing and integration research between landscape ecology and landscape architecture.In this study,based on the basic theories of landscape ecology,the waterfront landscape of Dapo Town was designed,with the aim to achieve ecological balance in planning,showcase biodiversity,and create a harmonious landscape ecological environment which can benefit both nature and people.This design combined artificial and natural elements while improving the natural environment,which promoted a harmonious relationship between humans and nature,thus enriching the spatial organization of the city,and playing a role in regulating the urban environment and climate. 展开更多

Through literature research, field research and urban design analysis methods, based on the self-organization theory, the evolution characteristics of the settlement space of Anju Ancient Town with significant characteristics of traditional mountain settlements were analyzed, and then its internal and external influencing factors were summarized. Finally, appropriate protection and development strategies were proposed, such as reasonably planning functional zones, breaking through the single structure, and creating a good living cultural environment. The innovation of this study is that it integrates the self-organization theory into the cognition of traditional mountain settlement space, and discusses the connection between the mountain settlement space and the traditional regional context under the modern development concept, so as to seek the benign protection and reasonable development of traditional mountain settlement space. 展开更多

As is known, the Great Red Spot (GRS) is one of the most mysterious sights in the solar system and is a strong storm that is quite large. According to the laws of hydrodynamics and gas dynamics, it should have disappeared several centuries ago, but scientists still observe it and cannot accurately explain this phenomenon. Since turbulence and atmospheric waves in the GRS region absorb the energy of its winds, the vortex loses energy by radiating heat. In the work, it is proved with a mathematical and non-classical approach that the GRS and anticyclones will live for a long time;otherwise, we had to first of all prove that the vortex threads (loops) and ovals could not exist. Based on these supports, mathematical methods prove their existence forever by observing a large vortex (GRS);moreover, they are sources of heat. When proofs are obtained, the results are consistent with the previous hypotheses of the researcher. The introduction of the work gives a comparison of various hypotheses;for example, one of them states that the decrease in the size of the GRS is only an illusory observation. Next, we first consider the applicability conditions for the mathematical justification of the hypothesis of the longevity of the Great Red Spot. The wind equation and the GRS are energized by absorbing smaller eddies and ovals, and this total energy is constant. With the help of the KH mechanism in the case of Brunt Vaisala, the frequencies (which can be calculated by a program with given formulas) are determined using very strictly mathematical evidence to substantiate the validity of the hypothesis about the longevity of Jupiter’s Great Red Spot. 展开更多

As China’s economy shifts from high-speed development to high-quality development,China’s urbanization also shifts from incremental expansion to stock optimization,providing a new direction for the transformation of urban villages.At present,the reconstruction work office of urban villages in small towns is mainly promoted based on government-led and villager main body in the initial exploration stage.From the perspective of policy orientation,to solve the main problems in urban villages in small towns,Zhuangqian Xiongjia Village,Fengcheng City was taken as an example,and the micro-transformation strategies of urban villages were put forward from the perspective of satisfying the appeals of the government,village committee and villagers,so as to provide some references for the transformation of urban villages in other small towns across the country. 展开更多

With the rapid development of tourism and urbanization in China,small tourism towns gradually grow toward prosperity.This paper takes Wan Town as an example to analyze the problem and countermeasures concerning the development of small tourism towns in China.There are a series of issues in the process of development of Wan Town,which includes uncoordinated architectural style,inaccurate market positioning,repeated cultural themes,and vulnerable linkage of the industrial chain.Based on the factor analysis,these development issues were classified into three categories:confusing architectural style,repetitive cultural theme,and weak linkage of industrial chain.To achieve the goal of sustainable development of small tourism towns,some countermeasures must be taken which include promoting the development of small tourism towns with the new rural revitalization,strengthening services improvement in small tourism towns,gathering industrial elements related to the tourism industry,and increasing tourism cultural connotation. 展开更多

Traditional Chinese medicine(TCM)has rich theories and techniques for health maintenance.Its cultural tradition of emphasizing health maintenance is not only related to its medical function of treating injuries and diseases and prolonging life span but also closely related to Daoism,which is the fundamental religious tenet of pursuing immortality in Chinese culture.As this paper reviews,the fanatical Daoist religious culture of pursuing immortality has influenced the formation of a medical culture in TCM that cares about longevity and values health and wellness.However,this health and wellness culture is more practical–it replaces immortality with longevity as the goal.The Daoist religious concept of longevity is preserved in the basic principles and ethical values of health care:it emphasizes the harmony and consistency of the spirit and the body.It turns a lifestyle of maintaining physical and spiritual health into the pursuit of an ideal state of life.As for the specific Daoist health techniques,there are various cases of inheritance,change or abandonment:TCM inherited most of the drugs and prescriptions from the Daoist longevity techniques based on natural medicines taking and formed a popular health culture of medicinal and dietary supplements;TCM also developed internal health techniques such as internal elixir and breathing practice from Daoist internal health maintenance techniques for physical health care and disease treatment;TCM did not completely accept recipe techniques such as inedia and sex manual from Daoism because they contradicted with its secularization concept,but their general value orientation of lightness and low desire also influenced its concept of health care. 展开更多
