Research On Establishment Of The Ecological Environment Information Tupu In Zhuhai Doumen District

Ecological destruction and environmental problems not only affect the sustainable development of the economy,but also affect the safety and health of human beings.People gradually realize that it is the foundation of the sustainable development to maintain and restore the health of ecological environment.Therefore,we need to grasp the status of the regional ecological environment,the relationship between the elements,as well as the pattern of their temporal and spatial distribution and evolution.It is worth further researching how to describe a region's ecological environment status and spatial pattern of ecological environment changes,and then make the appropriate planning measures.In this paper,Doumen District of Zhuhai has been chosen as the study region.The research started with theoretical investigation.Then combined with the characteristics of the study area,from the perspective of the elements of the ecological environment and the different aspects of the environment change,the composition framework of the eco-environment information tupu is constructed,including single element information Tupu and temporal and spatial evolutionary information Tupu.They could used to display the status and development rules of the ecological environment in Doumen District.Single element information Tupu related to various elements,including topography,climate,hydrology,soil,vegetation,human activities and land use.The evolutionary information Tupu involve the ecological environment change in the quantity,spatial distribution,speed,extent,spatial pattern and quality.On the basis of the composition framework,indicators of element information Tupu and models are selected and its influencing parameters are determined.Then the construction methods and full construction process are discussed.According to the composition framework,a set of doumen district ecological environment information Tupu is constructed,including single element information Tupu and temporal and spatial evolutionary information Tupu.Then,the ecological environment evolution type unit map and single element information map were overlaid,using two quantitative indicators,the importance index of ecological environment change and the ecological environment change area proportion,to find the the main types and the intensity of change based on the landform,climate,soil,vegetation elements information Tupu.Ecological environment evolution maps and ecological environment quality change maps are overlaid to find the correlation of ecological environment quality changes and ecological environment evolution.
