But it inevitably causes some impacts on the environment in the construction process. Because that the height of wind power generator generally exceeds 100 m,and visual range in plain region is farther,it is necessary to scientifically and rationally evaluate and analyze landscape visual environment impact of wind power generator in plain region. One wind power farm project of Zhanjiang is located in typical plain region of Guangdong coast. Referring to traditional analytic method of landscape visual impact and comparing with actual situation for the same kind of project in the region,results show that it is ＂ extremely sensitive＂ area at 0- 2. 5 km from wind power generator, ＂ very sensitive＂ area at 2. 5- 5. 0 km, ＂ sensitive＂ area at 5- 10 km, ＂generally sensitive＂ area at 10- 20 km,and non-sensitive area outside 20 km.展开更多

The construction of the ski field will change the landscape pattern of the assessment district, and the production capacity and stability of the regional ecosystem in a certain degree, and will exert an influence on the ecological integrality of animal and plant habitats. This paper assesses the structure and function of the landscape ecosystem in the Niuchangpin ski field at Shennongjia, by using the theory and method of landscape ecology and 3S techniques. Through the calculation and comparison of landscape diversity indices and landscape aggregation indices, the influence imposed by the ski field project on the regional ecological integrality and relevant sensitive ecological issues is predicted. The results indicated that biomass of the natural system would decrease by 430.26 t, and correspondingly the average Net Primary Productivity would drop to 881.55 g/m2·a. The construction of the ski field would not change the matrix status of woodland and, however, it has a strong ability to control the quality of ecosystem. Combining 3S techniques with landscape-ecological theory will help turn the qualitative assessment into the quantitive one on the eco-environment impact. In this study a significant exploration has been conducted in the aspect of ecological impact assessment of construction projects.展开更多
