Bicycle center infrastructure in a city

The paper deals with the bicycle center infrastructure in a city, which becomes popular every year, but is not yet studied properly. Little attention is devoted to the spatial development for two-wheeled vehicles, so there are many problems to be discussed and solved.The purpose of this paper is to determine the types of bicycle centers in the structure of a city, from the main and central to regional and peripheral that connect all urban areas. Moving along the bicycle paths from home to a large bicycle center and back to home, one can communicate in bicycle centers. Less functional peripheral centers provide repair services, bicycle rental and small recreation. The city of Rostov-on-Don is taken as an example.The following parameters are determined: optimum distance between bicycle centers of different types, their functional content, bicycle center location in the city. In the future, it is possible to arrange such centers in any city due to their unification.The model of the bicycle center network is proposed for the city of Rostov-on-Don, that are characterized by different area and multifunctional purposes for each district to attract people. The main bicycle center includes sports grounds, bicycle track, rock climbers, skate park, gyms, ski jumping hall and other sports facilities. Roof-top bike trails, amphitheater with a street stage, art spaces, go-karting can be arranged on the territory of these centers.

Degradation of Primate Habitat at Tesso Nilo Forest with Special Emphasis on Riau Pale-Thighed Surili (<i>Presbytis siamensis cana</i>)

The habitat of Riau pale-thighed surili (Presbytis siamensis cana) located in Riau province of Sumatra island between Siak in the north and Indragiri rivers in the south, has been seriously degraded in the last a few decades. This swampy peat land forest has been degraded by frequent burning during the dry season. These problems originated because of poor governance on the forest management, and the construction of two access roads by the owners of logging concessions and wood pulp plantations. This forest block consists of Tesso Nilo National Park, Kerumutan protected area, Production Forest areas belong to two companies, and a small recreation Park. It also contains one of the most important mixed peat swamp forests. Here, we tracked changes in forest cover before and after road construction using GIS and remote sensing imagery. Deforestation rates have increased from 1.5% per year before road construction to 9.28% per year after road construction, which means that the area of forest has decreased by an annual average of 8156 ha in Tesso Nillo alone. The habitat of Riau pale-thighed surili decreased almost up to 60% in the last decade after companies started their converting forest for oil palm and acacia and roads were built crisscrossed. If the trend of deforestation continues, further decline of population of habitat of this species is unavoided. Researches should be carried out in more details to understand the status of population of this subspecies before this subspecies disappears in the wild.
