During this study, total 55 species of birds were recorded, which included 31 resident and 24 migratory species. With statistics methodology, we analyzed the avian communities with 10 major environmental factors covering the park area, water percentage, vegetation species, canopy cover, shrub cover, grass cover, hill number, location condition, human quantity, path width, the study results indicated that: (1) the following 7 environmental factors were important to impact the structures of the avian community, they were park area, vegetation species, shrub coverage, grass coverage, hill number, location condition of the parks and path width; (2) the avian community of theses urban parks tended to deteriorate in the bird number and diversity; the man-made lake which was currently promoted in the park designing and planning process would not be good to attract the birds.展开更多

Because of the development of urbankation, however, most cities have lost their balance in the ecological enviionment although they seem to have the modem flavor of life. Integrating garden design with plant protection is an important measure to protect the ecological environment and maintain ecological balance. How to protect the plants in urban garden planning and design has become a problem to be solved by garden designers. In this paper, the relationship between garden design and plant protection was ekbofated, the status quo and problems of ornamental plant protection were analyzed, and measures to protect ornamental plants were proposed.展开更多

In this study, efforts were made to standardize vegetative propagation techniques for Lycium shawiL Nitraria retusa and Farsetia aegyptia. Effects of varying concentrations of rooting hormones on the success of rooting of hardwood cuttings of these species were studied in this research. Rooting in hardwood cuttings of Lycium shawii was enhanced （100%） by treating them with 1,000 ppm IBA, Ormone radicante in polvere （5,000 ppm NAA） and hormex （1,000 ppm IBA）. Treatment with 1,000 ppm NAA was found to be effective for Nitraria retusa, while marginal success was recorded in rooting of hardwood cuttings of Farsetia aegyptia when treated with 400 ppm NAA. Rooting in untreated cuttings was 80%.展开更多

In order to develop these structures and maintain population and its activity, the metabolism of urban areas needs a lot of external sources of energy and nutrients （water, food, materials...）, which produces heat waste, garbage, sewage and pollution which are some of the major problems for urban sites, and the related areas from it. This metabolism promotes major environmental changes in the urban areas, which promote stress on vegetation used in gardening. The main environmental factors that affect vegetation in urban areas are the same that have been defined in literature from long time ago, but now they are acting as the sum of complementary and synergic effects of these classical stresses at the same moment, in the same place, which happen due to the incredibly amount of energy that we place in the systems. This is called global change. Ecophysiological studies can provide objective information to be used as a tool to improve the vegetation management in urban areas from design to process, and consequently avoiding the potential vulnerabilities associated with global change. Present paper tries to show several examples about the plant response, measurement tools and vulnerabilities and adaptations to global change under urban conditions. It can be concluded that the large availability of vegetal material and the great technical development can be highlighted as strong points of gardening and urban landscaping while, as weak points, it could be mentioned the changing taste of consumers, which can force the introduction of new vegetal material with no time for adaptation, Urban gardening and landscaping can be considered to be exposed to global change, but in our opinion it is necessary to carry out more studies to determine the real degree of vulnerability of this activity to this complex kind of stress.展开更多

China＇s urbanization is a subject of great interest, one that has attracted the attention of people throughout the world. Whereas a handful of studies have assessed various aspects of urbanization（urban expansion, urban transition, urban-rural relationships, the spatial changes in urban and rural areas, motivations for sustaining rural places）, little is known of how to retain the indigenous character of rural areas in terms of landscape design. In this paper, the authors set out to contribute to this significant gap. They used Chengdu City and Five Golden Flowers（FGF） village in Chengdu＇s suburbs as case studies. A detailed description of the application of Ebenezer Howard＇s Garden City vision in Chengdu City was made; the Garden City vision was the key premise for FGF＇s ecotourism industry and successful conservation of landscapes with indigenous character. An analysis of the post-ecotourism landscape in FGF was accomplished using a typology method. Finally a set of landscape design methods for retaining indigenous character was proposed. The main conclusion of this paper was as follows： rural ecotourism can contribute to maintaining the indigenous character of rapidly urbanizing rural landscapes with the use of appropriate inheritance and renovation ways. The findings here may provide useful information for decision making by urban planners and policy-makers.展开更多

The results show that the average air temperature in both forest park and landscape forest is much closer to the pleasing feeling of human body temperature than that of the rest two greenbelts, where it is 1.782 ℃ and 0.837℃ in forest park as well as 3.084 ℃ and 2.140 ℃ in landscape forest less than that of roadside and resident-area greenbelts, respectively. In terms of mean air humidity, forest park and landscape forest are 3.034% and 7.563% higher than that of roadside greenbelt, and 1.205% and 5.734% higher than that of resident-area greenbelt, respectively, implying a sound humidity feeling of human comfort in the former two types. The air cleanness holds a descending rank as forest park, landscape forest, resident-area greenbelt, and roadside greenbelt, whereas the rank in inhalable particle concentration is completely reverse. In general, landscape forest and forest park that mainly consist of trees have a comparatively higher feeling of human comfort whereas roadside and resident-area greenbelts fluctuate irregularly to some extent for the measures studied. The four greenbelt types investigated could be summarized in human comfort as the following descending rank, forest park, landscape forest, resident-area greenbelt, and roadside greenbelt.展开更多
