The connotation of "amenity value" was elaborated,construction practices of "rural amenities" in Taiwan were reviewed,and its role in improving agricultural production environment and operation pattern,promoting rural economic development and quality of rural residents was highlighted.On this basis,a new rural value system was established from the perspectives of agricultural functions,industrial forms and economic forms,and the concept of "rural amenities" was defined.Moreover,the development targets of "rural amenities" were analyzed,including the overall objectives and those specific ones from 3 aspects:production,life and ecology,and finally suggestions on the development of "rural amenities" were proposed,that is,elaborate production,elegant life and refined ecology.Elaborate production focuses on maintaining the diversity of agricultural functions,promoting the upgrade and transformation of agriculture from the aspects of agricultural growth drivers,agricultural production mode,agricultural operation subjects,agricultural operation pattern,agricultural functions,and tries to bring new concepts to agricultural production and operation patterns through developing recreational agriculture and LOHAS rural tourism (LOHAS refers to Lifestyles of Health and Sustainability);elegant life emphasizes the optimization of rural communities,and the protection of cultural relics in rural areas;refined ecology highlights the construction of "rural amenities" from 3 aspects of rural ecosystem,rural living environment and farmland eco-environment. 展开更多

The current measuring methods of walkability,such as the walk score,consider that walking distance decay laws for all amenities are the same,which is not applicable to typical communities in China with plentiful resources.Therefore,the walking distance decay laws of multi-type and multi-scale facilities are studied.Firstly,based on the residents'amenity selection survey,the walking distance decay law of residents'choice of amenity was studied from three aspects,including the law of all amenities,the laws of different types of amenities and the laws of different scales of amenities.It was proved that the walking distance decay laws of different kinds of amenities showed a significant difference.Secondly,different amenities'acceptable walking distance and optimum walking distance were obtained according to previous studies and the decay curve.Amenities with higher attraction and/or a larger scale showed a longer acceptable walking distance and optimum walking distance.Finally,the binary logistic model was used to describe the relationships between walking distance,amenity type,amenity scale and the probability of one amenity being selected,the prediction accuracy of which reached 80.4%.The calculated probability obtained from the model can be used as the decay coefficient of amenities in the measurement of walkability,providing a reference for the site selection and evaluation of amenities. 展开更多

Based on the investigation of understory landscapes in mountain amenity forest in Guangdong, plant selection and spatial structure of understory landscapes were explored from the perspective of influencing factors such as terrain, stand structure, canopy density. It was proposed that plant selection for the construction of understory landscapes should use more indigenous plants, follow ecological attributes of plants and pay attention for ornamental value of plants. Three modes of constructing understory landscapes were proposed: ornamental, recreational and ecological. 展开更多

This study is intended to recognize the importance of cold-wind, which is one of the solutions to improve urban amenity, and verify the model that can analyze creation and flow of cold-wind. For this reason, KLAM_21 Model, which was developed by the German’s Meteorological Service, was selected and used for assessment of cold-wind creation and flow. As a result, the followings have been drawn through comparison with measured data and simulated data in the study area;for a mountain area, the simulation result of velocity and direction of wind has been indicated as similar as those in measured data. For a stream area in the city, only wind direction from simulation has been consistent with measured data whereas wind velocity showed a large difference between measurement and simulation. Finally, for the downtown area, wind velocity has shown a lot of differences between simulation result and measured data. Wind direction has also shown a large difference until midnight. But after midnight, model data have become similar as measured data. According to the verification of this study, the model used in this study for using urban-amenity improvement through assessment of creation and flow of cold wind is suitable to analyze the direction of cold wind that is generated in the periphery of the city and the overall flow within the existing urban area. But the results of wind velocity have shown the uppermost limit of the modeling in the simulation. That is, it could not reflect the site characteristics sufficiently. Therefore, if parameters considering the specific regional characteristics are sufficiently reflected, the result of simulations for reliability can be substantially improved. 展开更多

Amenity trees are an essential element of most urban communities,contributing significantly to human well-being and improving environmental quality.Good knowledge of the diversity and abundance of trees in our environment and their importance can help promote conservation,which is essential for sustainability.This study aimed at assessing the diversity and abundance of amenity trees on the premises of the International Institute of Tropical Agriculture(IITA),Ibadan Nigeria.The institute was divided into working and residential areas.The trees in the study area were identified using a walking and windshield survey.A total population of 2626 trees from 126 species and 42 families were identified on the premises of IITA.The highest tree population of 523 trees was recorded in the Tropical Crescent residential area with 321 trees of Lagerstroemia speciosa being the most frequent species.Across working and residential areas,Elaeis guineensis was the most frequent species accounting for 19.92%of the total tree population.A Shannon-Wiener Diversity Index(H’)of 3.383 and species evenness of 0.43 was obtained from the study area.The high values of diversity indices obtained indicate that IITA premises are rich in diverse tree species both indigenous and exotic hence should be referenced as a good urban landscape.The current management practices can be recommended for other institutions. 展开更多

In this paper,we study the properties of the scaled packing topological pressures for a topological dynamical system(X,G),where G is a countable discrete infinite amenable group.We show that the scaled packing topological pressures can be determined by the scaled Bowen topological pressures.We obtain Billingsley’s Theorem for the scaled packing pressures with a G-action.Then we get a variational principle between the scaled packing pressures and the scaled measure-theoretic upper local pressures.Finally,we give some restrictions on the scaled sequence b,then in the case of the set Xμof generic points,we prove thatP^(P)(X_(μ),{F_(n)},f,b)=h_(μ)(X)+∫_(X)∫dμ,if(F(n))is tempered andμis a G-invariant ergodic Borel probability measure. 展开更多

Rural gentrification is deeply characterized by institutional context and spatiotemporal heterogeneity.Based on a diachronic field investigation,this paper constructs an analytical framework for gentrifying rural community development(GRCD)with a“community”theoretical perspective and analytical approach,defines the concept of GRCD,and analyzes the main characteristics,formation mechanism and regulation path of a typical gentrifying rural community in the Panyang River Basin of Bama County,Guangxi.Driven by factors such as the complex flow and heterogeneous living space practices of the host-vip community,the longevity“myth”led by commercial capital and consumption demand,and multiple action logics and desertification community governance,great changes have occurred in the social space and material landscape of the rural longevity community.Such changes include comprehensive reconstruction of the resident population,surface interaction and social separation of the host-vip community,residential structure change and settlement landscape renewal,and delocalization of the healing landscape and lifestyle changes.We propose policy insights in three areas:public and localization institutional arrangements,shared and comfortable gentrifying rural community making,and inclusive and synergistic gentrifying rural community governance.Through these aspects,we provide insights from the Chinese case for the gentrification and community development of rural areas in the Global South. 展开更多

This paper develops a two-regional growth model with amenity, capital accumulation and regional public goods with public goods and fiscal policies. The economy consists of two regions and each region consists of the industrial sector and public sector. The industrial sector provides goods in perfectly competitive markets. The public sector, which is financed by the regional government’s tax incomes, supplies regional public goods. The public goods affect both firms and households. We show how to find equilibrium values of the dynamic system and simulate model. Then, we carry out comparative statics analysis with regard to parameter changes in tax rates, congestion and amenity. Our comparative statics analysis provides some important insights. For instance, a main difference between the effects of increasing the two regions’ tax rates on the output is that as the technologically advanced region’s (the other region’s) tax rate on the industrial sector is increased, the national industrial output, national capital employed by the economy, and the national wealth are increased (reduced). In the region which increases the tax rate, the wage rate, consumption and wealth per capita, output per labor force, the population, and land rent are increased, and the corresponding variables in the other region are reduced. 展开更多
