The Research On Based On Sports, Leisure And Urban Forest Landscape Study

Urban forest landscape is the main components of an urban green space. It's also the most dynamic organic composition in cities. It's growing popularity generally concerned by people with the composite functions. Such as its improvement of the urban ecological environment, rich urban landscape and providing recreation space and avoiding caclamity in urban places. The city's builders and policy makers have also increased construction inputs in the urban forest landscape. Combining with the current status of urban forest landscape construction, the causes for the issue of the city's ecological environment and recreational visitors, in large part are due to the layout of urban forest landscape unreasonablly. Therefore, this article analyzes China's urban forest landscape construction problems based on analysis of the construction theory and practice of urban forest landscape at home and abroad. Concluded that many problems of urban forest landscape largely due to forest landscape planning unreasonablly. And thus put forward a principle of landscape ecology as the center, combined with Urban Planning, Landscape Architecture and other related disciplines that all involved to build the system of urban forest lands status cape ideas. And take Changsha for example, analyzes forest landscapes of Changsha (including the landscape patterns, influencing factors, tree species selection, old and valuable trees, etc.), Based on the results, the author put forward countermeasure systems overall pattern of Changsha forest landscape based on healthful, leisure and urban forest landscape, and provide a basis for constructing urban forest landscape with local characteristics. The main conclusions were as follows:(1) The impact factors of urban forest landscape of Changsha are analyzed by the use of ambiguous comprehensive evaluation method. Finding out the potential development of Urban forest landscape assessment is very high, of which 27.52% is excellent,50.55% is good.. However, there are still areas for improvement. The overall assessment based on healthful, leisure urban forest landscape have the significant relationship between factors in Changsha. The correlation coefficient among "air negative ions," "Plant refined gas," "grass bushes and trees that the degree of integration" and "Landscape Layout" of these four factors were greater than 0.25 This shows that with the improvement of living standards, the public have higher pursuit on urban forest landscape, not simply the pursuit of coverage per capita public area, but pay more attention to air negative ions, plants refined gas, landscape and layout of these on the healthful, leisure content. Public green area per person and the urban green rate is impeding the main aspects of full enjoying,relaxing and getting healthy in urban forest landscape, so it should focus on effective countermeasures and measures quickly to turn it into a competitive advantage.(2) The application of principles and methods of landscape ecological pattern in landscape ecology, analysised the current status of urban forest landscape of Changsha City from the following aspects, such as basic composition, landscape diversity,landscape connectivity landscape isolation etc, Results show that the urban spatial layout of the park of Changsha is ideal enough:â‘ The total built green space area of Changsha is 4436.59 hm2, the per capita parkland is 6.54 m2, green land rate is 30.30%, green coverage rate is 35.53%. This shows that the urban forest landscapes have good foundations, which provides excellent conditions the based on healthful, leisure landscape planning of urban forest. But the landscape element types is relatively poor, and the area of landscape elements are quite different. Evenness and dominance index reflecting existence of dominant landscape elements in the urban forest landscape of Changsha Community parks are relatively small, the total number is being limited, and distribution is discrete, resulting in the high-degree of separation.â‘¡The local road transport system of Changsha is relatively well developed, and the sidewalk effects of green landscapes reach a certain level, but the green corridor for public to walk is scarce, the average rate of green space in major roads less than 11%, green coverage rate of only 44.42%, plantation of Roads is not very satisfactory. Camphor and Fa Tong on the road account for a half in the use of the landscape, indicating that the species of road in Changsha is relatively monotonous and lack of rich diversity. Overall, green area system in construction area of Changsha is relatively simple. The collocation of Joe, shrubs and evergreen, deciduous tree is not very reasonable and the species of fragrance, color, flower, fruit trees is lack so that it not reach the requirements of visual effects and ecological functions.(3) the application plant type of urban forest landscape of Changsha is too monotonous, for example, the amount of uses of the park's botanical species is only 124, accounting for 12.6% of woody plants in Changsha, the amount of the whole garden green plants also only is 192, only accounting for 10.5% of plants resources of Changsha. The parks and green corridors of the system of urban forest landscape focus on the use of conventional species, while many native species which are more values have not been well developed. Proposing to increase the domestication of wild native plants and their development in order to make application of plant resources in the city parks more diverse.
