An Empirical Study Of Environmental Impact Assessment Of Land Use Planning

Land is a basis for the existence of ecosystems,which is the most important economic activity factor of production. Rational use of land resources is essential to achieve sustainable development means,which concerns balance and stability of ecosystem and protection of basic human needs. The preparation and implementation of land-use planning is the basis and means of land use management on government. The scientific and reasonable planning of land use concerns the land use management of government; the authority of land use planning affects the standard and order of land use management of government. the specific practical planning affects the operability of land use management of government. Acoording to report to the Seventeenth National Congress of the Communist Party of China,it links with the work of land resources which gives affirmation on the achievements of the past five years,and advance in the face of difficulties and outstanding issues are pointed clearly which has put forward a series of new tasks and new requirements. Improve energy, resources, ecological and environmental conservation and improve law and policy of saving energy resources and protecting the ecological environment. Adhering to the basic state policy of conserving resources and the environment is vital to the immediate interests of the people and the survival and development of the Chinese nation. On the other hand,promote balanced development among regions and improve the pattern of land development. Promote a conservation culture by basically forming an energy- and resource-efficient and environment-friendly structure of industries, pattern of growth and mode of consumption. Before it,china has carried out two rounds of overall land use planning,which has played a very positive role to implement the basic national policy.Therefore, the implementation of environmental impact assessment of land-use planning is an important part of a new round of revising its land use planning throughout the country.Since September 1, 2003, according to People's Republic of China Environmental Impact Assessment" Chapter 2 Article 7, land use planning, regional, basin, the area of construction, development and utilization planning are prepared for environmental impact assessment in the planning process of revision and the planning for the environmental impact of the chapter by the State Council departments, the municipal district more than local people's governments and relevant departments. So far, more evaluation of the environmental impact is around the construction projects in China. However , environment impact assessment of land use planning is in the initial stage in China. It is crucial for the implementation of environmental impact assessment study of land use planning and establishment of a scientific system of indicators and evaluation methods.This paper discusses the current overall land use planning in China, which starts with the relationship between way of land use and environment. In this paper, we should know that land use is the major means of production activities ,and the change of land use is the process of land-use activities in the external manifestations, which is the natural attribute of land use and social attributes constantly meet with the development needs of their own dynamic process. The change of land use and its impact on the ecological environment for the understanding of the regional ecological environment is of great significance.Because the change of land use can cause many natural phenomena and the changes in ecological processes, such as soil nutrients and moisture changes in surface runoff and erosion, biodiversity and the distribution of biogeochemical cycling. Land use planning is that the various land-use activities for arrangements of time and space ,and its essence is that the optimal allocation of land resources which depends not only on the optimal allocation of land resources and natural conditions, and ecological conditions, socio-economic characteristics, traditions and culture.The core of this paper is that theory of sustainable development, ecological economics theory,people coordination theory, systems engineering theory, which proposes content, methods and principles, and indicators used for evaluation system system construction of land use planning environmental impact assessment. Then we use the theory for the environmental impact evaluation of examples of Fengdu County, Chongqing Municipality .We Study the various types of land use structure and layout of the environment and the quality system and its functions assumed by the value of resources, ecological function value, the functional value of impact of socio-economic factors, and its impact mechanism, and identify the function value environmental system resources function value, the value of the ecological function, the value of the various socio-economic function of land use structure and layout of the types and sensitivity of the environment and environmental suitability through the macro impact that land use exerts on the environmental system in Fengdu County. Land use related with environmental systems can be divided into the following subsystems from the major aspects in Fengdu County, such as system of geological environment, tourism resources, water systems, soil environment, and ecological environment. We use the value of ecosystem services as a system of environmental impact of land use planning, Where system factors in a quantitative division, accounting and compare caused by the change of land use of ecosystem services to evaluate changes in value of the last round of land-use planning by the environmental impact. It is expected for sustainable land use planning to provide useful reference.
