Evaluation Research On Ecological Safety Of Land In County Districts Of Anhui

The harmonious symbiosis between man and nature is not only the inexhaustible driving force and source of strength for modern development,but also the embodiment of the development of human civilization to a higher stage.Anhui Province is an important part of the "Yangtze River Delta" and is in the strategic position of national economic development,which puts higher demands on ecological civilization.The paper is based on Anhui's measurement and evaluation of the land ecological security of its county.The research has strong theoretical and practical significance.Based on the theory of human-land relationship,sustainable development theory and ecological economics,this paper builds the evaluation of land ecological security in Anhui Province based on the analysis of predecessors based on the county level and the application of ecological footprint analysis.The model evaluates the land ecological security of counties in Anhui Province.From the five aspects of per capita ecological footprint,per capita ecological carrying capacity,per capita ecological deficit,ecological pressure and ecological footprint of 10,000 yuan,the three regions of northern Fujian,Guizhou and Anhui have comprehensively compared the land ecological security of 61 counties in Anhui Province.analysis.The results show that:(1)For the per capita ecological footprint,the largest in northern Fujian,the smallest in southern Anhui,and the middle in central Yunnan;(2)for per capita ecological carrying capacity,the smallest in northern Fujian and the largest in southern Anhui.The middle region is somewhere in between;(3)for the per capita ecological deficit and ecological pressure,the ecological deficit is the largest in the northern region,the ecological deficit is the smallest in the southern region,and the middle region is between the two,corresponding to the north facing The ecological pressure is the largest,followed by the Yuzhong area,and the southern Anhui region faces the least ecological pressure.Further conclusions are drawn from the differences in the ecological footprint,ecological carrying capacity and ecological deficit of the county in Anhui Province.In particular,the land ecology in the northern part of Anhui Province has a large ecologica "gap",and the ecological pressure is large,and the land is subject to greater Load,etc.According to the research conclusions,this paper mainly proposes the following suggestions:increasing land productivity,creating brand effect;optimizing energy consumption structure;upgrading industrial institutions,coordinating land use patterns;innovating management functions;supplementing government welfare;and enhancing ecological awareness.
