Research On The Feedback Mechanism Of Spatial Population Factors And Space For Green Development

After a long period of primitive civilization and agricultural civilization,human beings entered into a brilliant industrial civilization in the eighteenth Century.The proposition put forward by the proposition of sustainable development,In the middle of the last century,mankind has stepped into the era of ecological civilization.It is a new social form,which aims at the harmonious coexistence of human and human,human and nature,human and society.After eighteen years,the CPC Central Committee and State Council attached great importance to the construction of ecological civilization,put forward a series of reform opinions,and green development is the proper meaning of ecological civilization construction,but also the trend of the times.In the economic and social development,due to the over exploitation of resources and consumption,as well as to the environment caused great destruction,has entered the overload capacity of resources and environment,in this case,how to ensure the sustainable development of economy and society,is the problem we face.In this context,relying on scientific and technological progress,improve the efficiency of resource use is the most effective way to solve the problem,and people are a factor of production,to participate in the production process is the core force to promote scientific and technological progress.At present,under the concept of green development,the influence mechanism of population factors on it is not clear.Therefore,it is necessary to study the role of human being as an important element in the green development.Based on existing research achievements of green development,and applying a serious theories including the system theory,the sustainable development theory and ecological civilization construction theory,this paper has constructed index system that contains 9 categories and 21 indices for evaluating green development space,from the purpose of hydrological protection,greening protection,cultural relics protection,geological disaster protection and environmental protection.Then,by using the method of geographic information and spatial analysis,the quantitative index is transformed into different types of green development spatial pattern.Combing the existing research on population resources,the population is divided into resource based population and innovative population,and the spatial distribution pattern of two types of population is supported by the GIS method.Then,the multiple logistic regression model was used to construct the feedback equation of population spatial elements and green development space,to establish the relationship between population and green development of the two mechanisms.This paper takes Chengdu as a case study,through the implementation of the above research methods,the following conclusions are obtained:(1)The growth of innovative population has improved the efficiency of land use and potential and leaded to decline in land demand.Through innovative population growth,while maintaining economic variables unchanged,green development space carrying suitable construction area of population decreased,innovative population improvement and population improvement compared with traditional resources,population density increased significantly.(2)The increase of innovative population has positive effect on green development;the suitable construction area is greatly reduced,the land utilization efficiency increased,limiting ecological factors and the ban on construction of building space to obtain the effective protection.The increase of the Traditional Resource-based population has a negative effect on green development.The suitable construction area has been greatly increased,and the area of moderate construction area has been significantly reduced,which greatly occupied the future potential use space of the region.(3)A set of analysis framework,which is able to express the elements,dividing the pattern,and examining the cause of feedback based on the spatial scale,has been established.It provides an effective way for the analysis of the harmonious relationship between human and green development space.
