Analysis of metropolis parking problems and solutions based on GIS

The rapid development of the social economy strongly promotes the urbanization and motorization.Meanwhile,parking problems become serious due to the long-term imbalance between parking demands and facility constructions.Thus there is an increasing urgency in finding solutions for parking problems.Based on the methodology framework of geographic information system（GIS）,the metropolis parking problems are discussed in this paper.The characteristics of parking demand and the reasons for parking problems are investigated in detail.Then,the basic parking principle and strategies for solving parking problems are suggested with the example of Beijing.The results are hoped to improve the parking environment in metropolis.

Exploration of Child-friendly Urban Park Design Strategies Based on Child Behavioral Psychology

By studying the behavioral psychology and needs of children,this paper analyzes the essence of child-friendly parks from the perspective of children,and discusses the design principles and key points of child-friendly parks,so as to provide a practical basis for the construction of child-friendly cities.

About the Optimized Design of the Parking Space on the Campus of a College

In recent years, with the large increase in the number of motor vehicles in colleges and universities and the lag in campus planning, the relative shortage of parking spaces on campus has become increasingly serious. Taking Baoding College as an example, this article analyzes the current situation of static traffic on campus and finds out the problem of parking on campus through questionnaire surveys and field surveys. Analyze the growth trend of the number of motor vehicles based on the data, use the GM (1, 1) model and the linear fitting model to predict the number of motor vehicles in the future, and determine the size and layout of the parking lot based on the campus size, functional zoning, and road layout. The big campus-based parking system planning method based on big data can effectively solve the problems of small sample data, low accuracy, and poor timeliness of traditional methods, which improves the practicability and scientificity of planning results.

Seasonal Variation in Air Temperature and Relative Humidity on Building Areas and in Green Spaces in Beijing, China

The cooling and humidifying effects of urban parks are an essential component of city ecosystems in terms of regulating microclimates or mitigating urban heat islands(UHIs).Air temperature and relative humidity are two main factors of thermal environmental comfort and have a critical impact on the urban environmental quality of human settlements.We measured the 2-m height air temperature and relative humidity at the Beijing Olympic Park and a nearby building roof for more than 1 year to elucidate seasonal variations in air temperature and relative humidity,as well as to investigate the outdoor thermal comfort.The results showed that the lawn of the park could,on average,reduce the air temperature by(0.80±0.19)℃,and increase the relative humidity by(5.24±2.91)% relative to the values measured at the building roof during daytime.During the nighttime,the lawn of the park reduced the air temperature by(2.64±0.64)℃ and increased the relative humidity by(10.77±5.20)%.The park was cooler and more humid than surrounding building area,especially in night period(more pronounced cooling with 1.84℃).Additionally,the lawn of the park could improve outdoor thermal comfort through its cooling and humidifying effects.The level of thermal comfort in the park was higher than that around the building roof for a total of 11 days annually in which it was above one or more thermal comfort levels(average reduced human comfort index of 0.92)except during the winter.

Landscape ecological characteristics in temporal changes of riverside open space in urbanized area

The aim of this paper is to clarify the pattern and process of changes of landscape in riverside open spaces in urbanized area.The area between the old banks of the Furukawa River in Hiroshima City was examined in this research.The land use maps of the study area were drawn at seven different times were analyzed,and the number,sizes and perimeters of all patches of all land use types were measured.In these areas,temporal patterns of land use change over the past 30 years were divided to three stages:19661976,19761988 and 19881997.As a result of human disturbance,the riparian forest patches in urbanized areas have decreased in average size and have also become longer and narrower.
