Research Of Green Space In Hubei Province Based On Geographical Conditions Survey

With the sharply rising of economic and the sustainable growth of living standards,city residents have proposed a more and more need for the improvement of urban environment. Studing about the urban green space ,analyzing the rationality of the allocation of urbanization under the background of urban green space,can provide meaningful guidance for the optimization of the distribution of urban green space in order to promote a full use of its ecological, social and economic benefits. Using land cover data of geographical conditions survey as main datas,permanent residents of Hubei Statistical yearbook as auxiliary datas,our study extracts green space information our study need to set up a corresponding index system of green space classification, and use the methods of the landscape pattern index,Theil index and Gini coefficient to analyze the landscape spatial differentiation characteristics of Hubei Province from the provincial level,partition layer and three main functional areas,then on the basis of that to analyze matched-degree between urbang green space and permanent residents and related environmental justice issues.The major and conclusions were surnmarized as follows:(1) The establishment of the green space information extraction and classification system.Green space data mainly comes from the surface coverage of geographical conditions survey,using processing methods of The combination of Geoway and Arc GIS,using the way of artificial classification and combination of inside and outside the industry,and the principle of closing to proximity and large,then refer to relevant criteria of the classification of green space at home and abroad to establish green space classification system..Results indicate that the way of processing data can guarantee the data accuracy and practicability,in order to accurately extract the green space information and set up green space classification system in line with the situation of Hubei,laying the foundation of studying urban green space accurately.(2) The analysis of Green space landscape pattern.Firstly, through the statistics of patch numbers,patch areas,the percentage of the area to overall analyze the characteristics of green space resources in Hubei Province.Secondly,through using the landscape index method to Calculate the landscape diversity , heterogeneity,agglomeration and fragmentation,the study can discusse the characteristic of green space landscape space differentiation in Hubei Province.Results indicate that the total amount of green space resources in Hubei is hugeand have rich types the total areas of green space are 175038.68km2.The biggest advantage type is the forest landscape,which intensively locates in the the area of Sheng Nongjia,but very little in Jianghan plain;on the contrary,the smallest advantage type is the garden landscape,Which intensively locates in the the area of Yichang and Huanggang.Farmland landscape are mainly distributed in Jianghan plain,but little in the area of Wuhan and Huangshi;The grassland landscape intensively locates in the mountain in the north of hubei and Mufu ,but little in the mountain of Qingba,the are of Sheng Nongjiaand Yichang Jinmen and Jinzhou. The percentage of Water landscape is low and Water landscape intensively locates in the the area of coastal counties in the middle reach of Yangtze river.The diversity and evenness index of green space landscape are bigger,but dominance index is smaller,and the degree of agglomeration is relatively poor in the mountainofWu,Daba,Wudang,Tongbo,Dabie,Mufu and soon; The diversity and evenness index of green space landscape are lower,but dominance index is bigger,and agglomeration is relatively rich in the Central and southern of Jianghan plain.(3) The study of compatibility between green space and permanent residents.using the methods of Theil index and Gini coefficient and visual expression by GIS,setting up analysis model,the study has a comprehensive analysis of the compatibility difference between urban green space resources and permanent residents in hubei province and points out existing problems and gives the corresponding countermeasures.Results indicate that the compatibility of green space- permanent residents is well and the fairness of Green space resource allocation is good,but that is not applicable to subarea.Most areas of Wuhan city circle have a poor compatibility of green space- permanent residents,eapecially in Wuhan..Large differences exists in green space resources configuration within subarea,and differences between the contribution are most come from Shiyan,Enshi,Wuhan,Yichang and Xiangyang.(4) The problems and countermeasure analysis of green space distribution.First,the crumbliness of green space resource distribution is large;second,there exsits unreasonable mpatibility between urban green space resources and permanent residents.Refactoring green space landscape,increasing the continuity of the green space and a balanced layout of green space by the population density,can improve the situation.
