Site geology: The geology of the Oak Park site is one of limestone-drift materials overlying regional limestone-bedrock (over which two broad groups of soils occur: light-textured gravelly soils derived from limestone, and more heavy-textured soils derived from till). The soil underlying Miscanthus-plantations used in the experiments the former type, with a perched clay/subsoil layer under the ...

city parks play an important role in the welfare of metropolitan people. higher species richness of birds can be considered as a reflection of the health of the park and may satisfy visitors to a higher extent being in a more natural environment. we studied the influence of area and shape of city parks on bird species richness and diversity. 13 parks from among the 35 main city parks in isfahan...

Assessing the concentration of potentially harmful heavy metals in the soil of urban parks is imperative in order to evaluate the potential risks to residents and tourists. To date, little research on soil pollution in China's urban parks has been conducted. To identify the concentrations and sources of heavy metals, and to assess the soil environmental quality, samples were collected from 30 u...

Trenholm for their supportive efforts throughout this learning experience. I give special thanks to Dr. Shober, my committee chair, for her encouragement, direction and commitment. I am also appreciative to Gitta Shurberg for her assistance in the field as well as laboratory. Abstract. Urban soils have highly variable chemical, physical, and biological properties compared to undisturbed natural...

The urban environment quality is of vital importance as the majority of people now live in cities. Due to the continuous urbanisation and industrialisation in many parts of the world, metals are continuously emitted into the terrestrial environment and pose a great threat on human health. An extensive survey was conducted in the highly urbanised and commercialised Hong Kong Island area (80.3 km...

A forested brownfield within Liberty State Park, Jersey City, New Jersey, USA, has soils with arsenic, chromium, lead, zinc and vanadium at concentrations above those considered ambient for the area. Using both satellite imagery and field spectral measurements, this study examines plant productivity at the assemblage and individual specimen level. Longer term growth trends (basal area increase ...

Problem: Children make little use of many neighborhood parks even though they have facilities for active recreation. Purpose: We examined the factors that bring children to parks, and aimed to understand how park visitation patterns differ between boys and girls, among children of different races and ethnicities, and between inner-city and suburban children. Methods: We surveyed children and th...

City-scale warming is becoming a serious problem in terms of human health. Urban green spaces are expected to act as a countermeasure for urban warming, and therefore better understanding of the micro-climate benefits of urban green is needed. This study quantified the thermal influence of a large green park in Tokyo, Japan on the surrounding urban area by collecting long-term measurements. App...

iranian women who, in the traditional conditions of the past and norms of the iranian society, have had a limited access to the public spaces of the city, with the changes taken place in our modern day society and factors such as education, employment and so on. nowadays, they have distinguished themselves in various fields and introduced their own issues and concerns to the society. however, i...
