Study On Environmental Impact Assessment Of Land Use General Planning

Since 2003, Chinese Environmental Impact Assessment Law has promulgatedand implemented, planning environmental impact assessment has become the focus ofmany scholars, and moreover, ministry of land and resources proposed that one of thekey of land use planning is to study how to coordinate land use and ecologicalenvironment issues in future. At present, coincided with the new round of revision of land useplanning, Land Use Planning Environmental Impact Assessment has been planning an importantpart. Tianshui is the only second core city of state-level economic zone <Guanzhong -Tianshui Economic Zone Development Plan> in Gansu Province, which is also animportant part of 'East Wing' in "Gansu Province Eleventh Five-Year Plan". Withentering a crucial period of economic and social development, land-use scale, layoutand ecological environment of Tianshui city will be impacted profoundly by the strongland demands. Therefore, it becomes an important question of the land use planningthat how to satisfy the needs of economic and social development and ecologicalenvironment.This thesis takes Tianshui City as the researched area, municipal general land useplanning as the assessing unit. Basing on sustainable development theory, ecologicaleconomic theory, human coordination theory etc, referring to the natural resources,environmental conditions and socio-economic development status of Tianshui City,the thesis constructs assessment indicator system of general land use planningenvironmental impact in Tianshui City that relating to economic and social, naturalconditions, the urban environment and urban landscape, first using landscapeecological analysis and harmonious environment analysis methods to calculate theland use status of counties in Tianshui City ,and then using DPSIR conceptual model,ecosystem service function evaluation method and graphic overlay method to predictand evaluate comprehensive environmental impact of the general land use planning inTianshui City, with hoping to provide references for realizing an orderly developmentof regions and spatial equilibrium, ultimately achieving sustainable development onland use, resources and environment in Tianshui City. The thesis includes thefollowing seven chapters:Chapter 1 is the introduction. It introduces the research background, researchsignificance, as well as the research thinking and research diagram.Chapter 2 is the review on environmental impact assessment. It mainly introduces the concept of environmental impact assessment and studies the focal points, theassessment indicator system and the applicable situation in area studies from thedomestic and international theories of environmental impact assessment.Chapter 3 is the introduction on basic theories and research contents of thegeneral land use planning environmental impact assessment. It mainly introduces thetheories of sustainable development, ecological economics, human coordination,systematic and landscape ecology, also the procedures of land use planningenvironmental impact assessment and the main contents of this paper.Chapter 4 is the general land use planning environmental impact assessmentmethod. Through presentation and comparison of 9 methods including checklists,matrix method, it identifies evaluation methods of the general land use planningenvironmental impact assessment in Tianshui City.Chapter 5 is the overview and calculation of the land use status in Tianshui City.It introduces the natural resources, environmental conditions, analyzes economic andsocial development level, land-use conditions, and then uses landscape ecologicalanalysis and harmonious environment analysis methods to calculate the land use statusof counties in Tianshui City.Chapter 6 is the research of general land use planning environmental impactassessment. Based on the theory and actual situation of Tianshui, the thesis builds theindex for land plan environmental impact assessment of Tianshui City from theeconomic and social, natural conditions, the urban environment and urban landscape constructed,natural disasters. It uses DPSIR conceptual model, ecosystem service functionevaluation method and graphic overlay method to predict and evaluate comprehensiveenvironmental impact of the general land use planning in Tianshui City.Chapter 7 is the conclusion and expectation. It summarizes the main researchfindings, innovations and inadequacies of the thesis, and then gives myrecommendations in future research.
