Land Ecological Environment Quality Assessment And Analysis Of ITS Influence Factors

Land resources are the material basis of human survival and development. However, with the increasing population and the rapid development of economic and social development, Excessive human exploitation of land resources, leading to a series of ecological and environmental problems. The increasingly serious environmental problems of soil erosion, soil pollution, land salinization, reduction of arable land resources, water pollution, land damage and biodiversity loss etc, aggravate the contradictions between man and land, restricted the sustainable economic and social development. As industrialization and urbanization move forward, ecological environmental problems become increasingly hard constraints of economic and social development in Jiangsu. Therefore, It is of great significance to realize the coordinated development of society, economy, ecology and the sustainable land use, objectively and comprehensively grasp the regional land ecological environment, explore influencing factors of the land ecological environment, propose effective measures to protect the environment.On the basis of the domestic and foreign research results and the relevant theory. Construct the analysis framework of Jiangsu socio-economic development impact land ecological environment, from three aspects of economic development, social development and institutional agreements. By land ecological index, portray the pros and cons of land ecological environment conditions, and the introduction of STIRPAT model to analyze the drivers of land ecological environment. Finally, empirical analysis on the influencing factors by Jiangsu Province In remote sensing and GIS technology, and make the corresponding policies and suggestions.(1)The influence mechanism of Land ecological environment quality. Based on the research of inherent relationship between regional development and land ecological environment. Constructing the analysis framework of impact mechanism of Land ecological environment quality, from three aspects of economic development, social development and institutional agreements.Economic development acting on land ecological environment by way of scale effect,structure effect and technology effect. Social development acting on land ecological environment by way of urbanization, population development and lifestyle changes. Institutional arrangement acting on land ecological environment by way of Government intervention, market regulation and social participation. Market mechanisms and government mechanism is an important mechanism for protecting the environment, meanwhile both exist deficiencies, Social mechanisms can compensate for their insufficient. Currently, because it is lack of the condition of social mechanisms protect land ecological environmental, leading to weakened social mechanisms,but improving the direction of the ecological environmental protection. The ecological environment.(2) The assessment of land ecological environment. The evaluation results are more in line with the ecological status of Jiangsu, the method is feasible. Jiangsu land ecological environment quality index was 54.25, in the general level, and ecological environmental conditions remain stable. The ecological environment of Yangzhou, Suzhou and Changzhou is better, and Xuzhou, Lianyungang, Suqian is relatively poor. Generally speaking, Most of Jiangsu Province, is good, only a small part is poor. Meanwhile, the ecological environment of south part of the Huaihe River is better than north part of the Huaihe River.(3) The analysis of Land ecological environment influence factors. The results showed that land ecological environment is mainly affected the GDP, urbanization, fertilizer, population density, the proportion of non-food consumer and industrial solid waste generation etc. From the relationship between factors and land ecological environment, it is positive correlated with the proportion of non-food consumption, GDP, urbanization level,it is negative correlated with fertilizer population density and industrial solid waste generation. From the influence degree of factors, the proportion of non-food consumer is the greatest impact factor, Population density and urbanization followed it, and GDP, fertilizers, and industrial solid waste generation are the relatively small impact factors.Based on the conclusions, the paper proposes the policies and recommendations about protecting the ecological environment and alleviating land resources pressure. First, promote low-carbon life, optimize consumption structure, raise the proportion of non-food consumption expenditure. Second, control population, guide population flow, promote rational distribution of population. Third, balance the quality of urbanization and the ecological environment protection. Fourth,transform the economic development pattern to promote the rapid growth of the green economy. Fifth, scientific fertilization and improve fertilizer use efficiency. Sixth, control pollutant emissions and strengthen ecological environment management.
