Study On The Green Space Landscape Pattern Analysis And Landscape Ecological Planning Research In Yuquan District Of Hohhot

The urbanization bring environmental problems including air pollution,water pollution,acid rain,municipal refuse and noise etc,and ecological problems including shortage of the urban green land, the loss of landscape diversity, and sharply decrease of biology and so on.These problems have already threatened the existence of the mankind seriously.Urban green space as main part of natural productivity,is the one of necessary conditions to improve the city's ecological environment,urban style and open conditions,protect sustainable development of urban.This study put Yuquan District of Hohhot as the research object, use landscape ecology and its related theory,research methods and quantitative analysis methods,use Quickbird image,Huhhot Statistical Yearbook and related information as the main source of information,in the geographic information system software Mapgis6.7 support,extract green land information to green land system in Yuquan District on the level of research,quantitatively analysis green landscape pattern and structure urban green space in a scale of city sapce,and preliminarily study on this basis of landscape ecological planning in Yuquan District.The results show that green landscape of the Yuquan District in Hohhot dominated by large patches,inadequate distribution of small and medium-sized plaque.green landscape types are distributed unevenly,the larger difference between the type of green landscape, green landscape is not high overall diversity,landscape greater dominance.roads green spaces,residential green space,green subsidiary units are smaller and broken high.the diversity of public green space,the highest evenness index,the minimum residential green space.residential green space dominance of the largest and the smallest is public green space.in the separation index,the largest one is residential area. Conduct a preliminary study of the building by analysing green landscape and evaluation of the status,according to the construction of urban green space landscape ecological principles and the basis for landscape ecology green Yuquan District,and put forward reasonable suggestions.
