Study On The Spatial Structure Mode Of Small-scale Towns In Longnan Mountainous Area

The spatial structure mode which matches to nature ecological environment is the basement of human settlements sustainable development.In the mountainous area which reserves the original ecological environment,treating well with the relationship between human and nature is necessary.Therefore the paper explains the study on spatial structure of towns human settlements in Longnan mountainous area.Based on investigation of the ecology background in Longnan mountainous area, revolving around the relationships of the human,space and nature,the paper inquiries into the processes and ways of spatial structure evolution,analyzes the ecological restrictions of the spatial mode evolvement of human settlements, then is aware of the opportunities which implicit in these restrictions.The study puts forward that investigating the processes and regulations of the spatial mode evolvement of human settlements honestly,should be the credible method for getting the ideal spatial mode. By discussing the processes and ways of the spatial mode of human settlements deeply, then understanding the restrictions brought by the local geography environment, the paper tries to establish a premise for holding the current opportunities.Therefore,it is also the basement for the sustainable development of human settlements.
