With the objective of analyzing the indices of concentrations of atmospheric pollutants and estimating how these levels can affect human health, this work consists of a study of the analysis of air quality in the intense trade region of Fortaleza. For this, the analysis zone was divided into three perimeters (Major - Medium - Minor), where each perimeter was analyzed at 7 am, 12 noon and 5 pm. Concentrations of the type of O<sub>3</sub>, particulate matter (PM<sub>2.5</sub> and PM<sub>10</sub>), CO<sub>2</sub> and HCHO were collected. Our results demonstrate that most of the analyses are within the limits of current legislation;however, at certain times and perimeters, the analyses of CO<sub>2</sub> and HCHO exceeded the established limits. In view of the above, we conclude that public policies to control air quality are necessary to reduce the damage to human health and the environment caused by pollutants.展开更多

Traditional studies of the external environment of human settlements, however, frequently overlook the combined impacts of wind and snow environments. Furthermore, in urban meteorological studies, it is impossible to accurately assess the wind and snow environment in specific areas or locations. In this study, a refined Computational Fluid Dynamics(CFD) multiphase flow numerical method was used to simulate a planning space's wind and snow environment. The study classified the Snowstorm Weather Grade(SWG) by incorporating the Snowstorm Weather Index(SWI) to generate calculation results of the wind environment and snow environment. In particular, 150 measurement points in the planning space were chosen for analysis and evaluation of their wind and snow environments. The results demonstrated that the SWI index can effectively correlate to the wind and snow environment calculation results. In addition, the graph of SWI showed that 55% of the measurement points had a moderate wind and snow grade SWI, which exceeds the average grade for the entire region. The practical application shows that the wind and snow environment assessment indexes and technical methods developed in this paper can be successfully applied to wind and snow environment studies in other cold cities.展开更多

For a long time, the independence of the two is more prominent than their organic connection. This research has made preliminary considerations from three aspects. First, it concerns infusing the concept of ecology, contemplating and demonstrating space, as well as reducing the incidence of plant diseases and insect pests of urban green land. Second, the arrangement of flowers and trees for the planning and design of urban green land should comply with the biological attributes of flowers and trees to realize the organic unification of biological and scenic attributes of flowers and trees. Third, the planning and design of urban green land should attach importance to the organic unification of biological and scenic attributes of lawn grass seeds and reduce the difficulty of maintaining lawn. This research attempts to reduce the pressure of maintaining urban green land from the beginning, i.e. the planning and design of urban green land. It also tries to reduce the cost of maintenance and management to the realize planning and design goals of urban green land and the sustainability concerning its maintenance and management and arrive at the mutual unification of the planning and design as well as maintenance and management of urban green land.展开更多

It hopes to provide a reference for satellite urban planning theory guiding practice, so as to control and evacuate urban people scientifically, promote the functional orientation and spatial distribution balance of towns and cities, and finally facilitate the sustainable development of living environment.
文摘Based on overview of development history and research advances of do- mestic and foreign urban green space system planning, this paper made clear rele- vant concepts of the urban green space system. Urban green space system is a key region for protecting ecological resources. Taking Chongqing Economic and Technological Development Zone as an example, on the basis of in-depth survey, it made a systematic study on green space system planning combining current situa- tions of green space and regional spatial characteristics of Chongqing Economic and Technological Development Zone. It discussed how to restore and build urban green space system, protect ecological environment, and promote regional economic de- velopment and harmony between human and nature through design of ecological technologies and landscape in the ecological planning of urban green space system.

文摘The sustainability of the planning and design goals of urban green land and that of its maintenance and management are mutually related and act as an organic whole. For a long time, the independence of the two is more prominent than their organic connection. This research has made preliminary considerations from three aspects. First, it concerns infusing the concept of ecology, contemplating and demonstrating space, as well as reducing the incidence of plant diseases and insect pests of urban green land. Second, the arrangement of flowers and trees for the planning and design of urban green land should comply with the biological attributes of flowers and trees to realize the organic unification of biological and scenic attributes of flowers and trees. Third, the planning and design of urban green land should attach importance to the organic unification of biological and scenic attributes of lawn grass seeds and reduce the difficulty of maintaining lawn. This research attempts to reduce the pressure of maintaining urban green land from the beginning, i.e. the planning and design of urban green land. It also tries to reduce the cost of maintenance and management to the realize planning and design goals of urban green land and the sustainability concerning its maintenance and management and arrive at the mutual unification of the planning and design as well as maintenance and management of urban green land.
文摘The importance and complexity of prioritizing construction projects (PCP) in urban road network planning lead to the necessity to develop an aided decision making program (ADMP). Cost benefit ratio model and stage rolled method are chosen as the theoretical foundations of the program, and then benefit model is improved to accord with the actuality of urban traffic in China. Consequently, program flows, module functions and data structures are designed, and particularly an original data structure of road ...
