Aesthetic evaluation of yardang landforms landscape:the Dunhuang Yardang National Geo-park example

Dunhuang Yardang National Geo-park, situated in the Gansu Province of northwestern China （40°25′36″N-40°33′10″N, 93°00′00″E-93°13′30″E）, was chosen as a research locality of aesthetics evaluation of yardang landforms landscape. The yardang landforms landscape is a composite structural system of patch-corridor-matrix, with four landscape unit elements as dense group, sparse group, single body and remnant. The study of the landscape aesthetics spatial pattern of Dunhuang Yardang National Geo-park shows that yardang dense group, sparse group and single body provide the greatest contribution to the aesthetic value of yardang landforms landscape. Yardang bodies are scarce, unique, irreplaceable, and priceless resources in yardang landforms areas. However, they are easily destroyed under the influence of the natural and artificial factors. Therefore, when the tourism potential of yardang landforms landscape is exploited, the protection should be fully improved.

Research on Ecological Space Planning Oriented Urban River Landscape Planning

Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.

The Architecture Design Based on the Landscape Conditions: Taking the Architectural Design of Subsidence Area for Example

The relationship between architecture and people, architecture and city, architecture and nature has always been the soul of architectural design. In the architectural design, study on the relationship between architecture and nature needs "site analysis"(mapping), and "natural environment" tends to affect the design results[1]. In many special areas, the design needs analysis of geology, geomorphology, hydrology, vegetation and other landscape elements. Coal mining subsidence area is the product of the conf licts between human activities and natural environment in the process of industrialization. As the research object, coal mining subsidence area can be a good study object to demonstrate architectural design strategies and methods based on landscape, and fi eld defects of the site may be the origin of architectural space organization: architectural concept, structure, morphology, spatial organization are all from the landscape elements.

Strategies for the Construction of Vernacular Landscape in Urban Gardens

Vernacular landscape is the carrier of traditional techniques and local culture.The construction of vernacular landscape has gradually become the basic direction of modern urban garden design.Based on the analysis of the extraction and application of vernacular landscape elements,the application forms and design principles of each element in urban gardens are pointed out.At the same time,taking the artistic expression method of integrating vernacular landscape elements into garden landscape as the starting point and combining with case analysis,the design principles and main planning points of building vernacular landscape are put forward,and some strategies for the construction and protection of vernacular landscape in the planning of garden landscape in different regions are proposed.

Elements and Element Components of the Rural Landscape in Linpan of Western Sichuan in Relation to Perception,Preference and Stress Recovery

Natural environments contribute to people’s perception,preference and health restoration.Many researchers have focused either on the positive effects of overall rural environments on stress recovery or concentrated on the perception and preference aspects of the rural landscape,but few have integrated perception,preference and stress recovery simultaneously.This paper developed a framework which includes 11 elements and 38 element components related to Linpan,China,and distributed it online as part of a survey.As a result,a total of 324 valid questionnaires were collected.The questionnaire included demographic details,perception and preference degree for Linpan,as well as self-estimations of stress recovery.Stepwise multiple linear regression was employed,and revealed 16 significant predictors for the perception,preference and stress recovery in rural environments.In terms of elements,atmosphere and imagery were the two elements that could be best perceived,while woodland,farmland,water,residence and road were the five most important elements for the preference.Moreover,seven elements were also identified as significant predictors for stress recovery.Among the element components,tranquility as well as road and water proximity were the two significant predictors for perception,while wide visibility as well as woodland and residence blending contributed significantly to stress recovery.The five element components of woodland interior,vegetable field,stream,courtyard space and branch road each had a significantly predictive ability for preference and stress recovery.These findings extend the understanding of the perception,preference and restorative properties of rural environments through the combination of elements and element components in Linpan of Western Sichuan,helping to improve the quality and characteristics of rural external and internal environments and create health-promoting environments.

Research on Thermal Comfort of Outdoor Space in Summer Urban Park: Take Mianyang Urban Park as an Example

One of the factors for the evaluation of the space environment is the comfort of outdoor activities spaces in urban parks. The space composed of different landscape elements has different microclimate environment. In this paper, in order to evaluate the role of thermal comfort in influencing resident’s assessment of the outdoor space and activities of the park, a thermal comfort survey was conducted on the outdoor open space of Mianyang Urban Park in summer. In this article, meteorological surveys, questionnaire surveys and observation of park attendance are selected to collect data. The physiological equivalent temperature (PET) assessment was selected as the index to evaluate resident’s thermal comfort level, and the comprehensive evaluation and analysis of the spatial thermal environment of different outdoor landscape elements in the park. The overall comfort of current visitors is mainly influenced by their subjective heat perception voting (TSV). In this article, we focus on providing microclimate adjustment considerations for urban park landscape design, and may help people understand the outdoor thermal comfort of Mianyang in summer, increase the using time of outdoor activities, and promote the use of outdoor space.
