Zhengzhou City Park Green Space Plant Diversity And Landscape Research

City Park is the main body of city greenbelt system, city park plant has multiplefunctions of greening and beautification, purification of the city, also plays an important rolein the garden state of mind and mental health. Research on the plant diversity of city park, onone hand, can provide a basis for plant protection, on the other hand, for the current cityplanning and construction of green space, plant composition, plant introduction and reference.In this paper, through the investigation on plant diversity in Zhengzhou city park green space,analyzed the status of plant diversity in Zhengzhou city park green space, and analyzes the6Park plant landscape and the existing problems.1.the zhengzhou city park green space plant a total of73families,158genera and73species, including7of14genera,25species of gymnosperm, and66families,144genera and212species of angiosperms,7families21genera and23species of monocotyledon anddicotyledon59families and123genera,189species Rosaceae15genera and32species oflegume9genera17in oleaceae June12component in plots.131kinds of local tree species,introduced tree species,80kinds of domestic, imported species of27.2. different Park plant richnessTrees Margalef richness index showed:Zhengzhou Green Expo Garden(30.80) graterpeople’s Park grater Bauhinia Hill Park grater Bayside Kong Park grater Lin Yuan ofZhengzhou grater Forest Park(5.22). Shrubs Margalef richness index showed:ZhengzhouGreen Expo Garden(15.25) grater people’s Park grater Bauhinia Hill Park grater BaysideKong Park grater Lin Yuan of Zhengzhou grater Forest Park(0.374).The Shannon-Wiener index for trees:Zhengzhou Green Expo Garden(1.692) graterpeople’s Park, Bayside Kong Park grater Bauhinia Hill Park grater Lin Yuan of Zhengzhougrater Forest Park(1.033). Shrubs Shannon-Wiener index performance is:Zhengzhou GreenExpo Garden(1.213) grater Zijingshan Park grater Forest Park grater Zhengzhou people’s Parkgrater Lin Yuan Park grater Bayside Kong(0.889).The Simpson index for trees:Zhengzhou Green Expo Garden(0.968) grater people’s Parkgrater Bauhinia Hill Park grater Bayside Kong Park grater Lin Yuan of Zhengzhou graterForest Park(0.868).Shrubs Simpson index performance is:Zhengzhou Green Expo Garden (0.942)grater Zijingshan Park, people’s Park grater Zhengzhou Park grater Forest Park graterLin Yuan grater Bayside Kong(0.190).Tree species evenness index is:People’s Park grater Lin Yuan of Zhengzhou graterZijingshan Park grater Zhengzhou Green Expo Garden grater Forest Park grater BaysideKong Park(0.810).Shrub species evenness is shown as:People’s Park(1.556) grater Lin Yuanof Zhengzhou grater Zijingshan Park grater Zhengzhou Green Expo Garden grater BaysideKong Park grater Forest Park(0.301).3.Based on the investigation and Analysis on plant diversity of park, summed up thereasons affecting the city park plant diversity: park construction purpose and location, parkconstruction time, park management and maintenance. Finally, rich Zhengzhou city parkgreen space plant diversity and landscape proposal, provide guidance in Zhengzhou city parkgreen construction.4.put forward the zhengzhou city park green space plant diversity and rich plantlandscape proposal:(1) make full use of native tree species, according to the principle of optimal tree,all-round development of native tree species of landscape plants.(2) The application of herbaceous flowers, rich increase the diversity of groundcoverplants.(3) Plant expert guidance park ecological construction. In order to maximize the plantdiversity and landscape richness, expert guidance park management departments of planttransplantation and adjustment work.(4) Effective plant introduction and management Follow the principle of"people-oriented, service citizens", park according to their own characteristics, appropriateintroduction of high ornamental value of exotic species, in order to improve the plantdiversity.
