Studies On Plant Diversity Protection Plan Of Greenland Systerm In Qitaihe

Qitaihe City, Heilongjiang Province is an important industrial city, in order to meet multiple targets , such as the city's ecological environment and the harmonious development of the coal industry, reflect the local characteristics to create a garden city, paper through investigating in three types that the city of species diversity, ecosystem diversity and ornamental diversity. analysis the plant diversity current situation , and finally writes a series of planning measures to protect plant diversity..Papers on urban plant diversity assessment, including analysis of the layout of urban green space. Analysis the features of various types of urban green space, can effectively alleviate the coal pollution on the city against; Analysis of the composition of plant resources in the city, the regional characteristics of species composition, vegetation composition of the geographical characteristics of components. Through comparative study, select advantage family and genue, find out suitable plant family and genue growing in Qitaihe; Vegetation community diversity, measured on artificial-natural forest and artificial forest diversity of the community, through a comparative analysis of the difference between the level of community diversity reasons. Ornamental the type of plant diversity, analyze the ornamental type characteristics on tress, shrub and grass; Rare and endangered species diversity, expand the scope of protection species according to the current situation, the development of plant protection in Qitaihe City Directory; Introduction and acclimatization of plant diversity, according to the characteristics of introduction and acclimatization species in the last few years, determine the future focus of the protecting work.Summary of the current situation problems, to identify protection measures based on home and abroad, through multi-level layout of green space to protect the plant diversity and the establishment of the plant protection network to reflect the structure of urban landscapesd and reach the ultimate goal.that is protecting the plant diversityPapers in the course of the study reached the following conclusions: the uneven distribution of urban green space system, the Xinxing area less green area and the layout of the shelter-forests difficult to alleviate the dust pollution in cities;tress,shrub and grass imbalance rattan, the majority of grass and fewer home species; vegetation geographical composition diversity, in temperate ingredients mixed a small tropical ingredients; city's four urban imbalances in the distribution of plant species, at least in Xinxing area, the largest peach mountain area; parkland has the highest diversity index among different types of green space, Roadland has the lowest diversity index.A large number of native plant has not been development in the city, the focus of future work is strongly acclimatized native plants, an appropriate introducti abroad plant.Qitaihe city is not done on urban resources survey and system evaluation, nor specific targeted measures to protect plant diversity, as a result, this paper will provide a reference to the future biodiversity protection in Qitaihe City, but also provide case for this direction research.
