The Research On Ecological Function Regionalization In Tianmen

The survival of mankind cannot be separated from the support of ecological environment,the economic development and social progress also cannot do without it.For a long time,people are blind to the development of eco-environment and natural resources,only taking the regional development direction and manner of development into consideration from the angle of economy and society development.Thus,it has led a series of environmental problems.Based on the calculation of the economic strength,the ecological sensitivity,the ecological footprints,the ecological capacity of each township in Tianmen,this research used the GIS technology to carry on the spatial analysis,obtain the result of Ecological function zoning by using cluster analysis to integrate data.Finally,according to the actual situation of Tianmen,this research puts forward the corresponding suggestions for each partition function of construction planning.In the hope that it can provide a scientific reference for the strategy of sustainable development and the improvement of the ecological environment.At present,the function division is less studied at the city level.In this paper,I have thought the ecological function zoning at the city level of Tianmen.This is the innovation of this paper.The main parts of this research are as follows:(1)Analysis of regional situation.This research analyzes the natural state of the environment,socio-economic status,the ecological environment quality status,calculates and evaluates the comprehensive economic strength of each township.The results show the socio-economic situation in Jingling,Duoxiang,Houkou,Yukou,Zaoshi and Duobao develop well,and the rest develop less.(2)Analysis of ecological sensitivity.This research chooses terrain,the water environment,the habitat as the first level appraisal factors to analyze the elevation,slope,,rivers and lakes,vegetation specifically.The extremely sensitive area?highly sensitive area?moderate sensitive area account for 14%of the total,lower sensitive area account for 70%,insensitive area account for 16%,and assessed the Ecological Suitability according the results above.(3)Analysis of ecological footprints and ecological capacity.According to the data of"Tianmen Statistical Yearbook" of 2013,the ecological footprints and ecological capacity of each township are calculated.The ecological deficit of the whole of Tianmen is made clear by the results.Demands are far greater than the supplies of resources.The ecological deficit per cap is-1.25576 hm2 in Baimaohu.(4)The results of ecological function zoning.After the cluster analyzing of economic strength,ecological sensitivity,ecological footprints and ecological capacity,the result of ecological function zoning has been made to ecological city zone,ecological agriculture zone and ecological industry zone.(5)the research puts forward some reasonable ecological protection proposals,based on the characteristics and development orientation of each ecological function regionalization,...
