| In recent years, as the world population growth and global and regional economic development, structural problem such as"Population, Resources, Food and Environment"has become a global common problem. In particular, the strengthening of human activity, activities of regional expansion, making natural ecosystems are increasingly affected by the interference of human behavior.Ecological environmental degradation, natural disasters increased have seriously affected the smooth development of human society.Ecological environment is closely related to human survival and development of the environmental foundation, which is the eco-system and the organic combination of environmental systems, including biological and abiotic ecological factors of the ecological factors, such as vegetation, water, land, climate, physical geography conditions and artificial conditions; while the eco-environmental investigation is to use effective methods, in time or space within a specific geographical area or ecosystem eco-system polymer type, quantity, structure and function, etc. in one or more elements of regular, systematic measurement and observation process, and its aim is to establish the effects of each factor in the environment and ecological system in place to reflect the relationship between the ecosystem in order to eventually achieve the status and development trend of the evaluation and prediction.This study ,concluding a large number of domestic related literature, used theory of"land use / land cover change",and based on"3S"technology,guiding by《Eco-environment assessment of technical specifications (for trial implementation)》,as a guide for regional eco-environmental evaluation of the application requirements, as the research object of the ecological environment in western Jilin Province, investigated and researched the ecological environment in western Jilin Province by different time and space scales , in line with practical, science, advanced principles. |
