Abstract:

Researches on engineering construction in permafrost areas have been carried on from early time, while the focus on the resulted ecological environmental impacts took place relatively late. From a viewpoint of impacts on ecological environmental elements, concerned studies mainly focus on the impacts on permafrost, vegetations, wetlands, desertification, wild animals and natural reserves. The researches on impacts on permafrost are relatively more mature, which lies on the fact that different impact assessment models based on thermal stability parameters have been set up. Further from a viewpoint of ecological environmental impact prediction and assessment, concerned studies mainly focus on prediction and assessment of permafrost and erosion impacts. It can be concluded from existing references that, there are problems as regard to researches on ecological environmental impacts of engineering construction projects in permafrost areas, as follows: (1) the connection between ecological environmental deterioration and permafrost degradation is not effectively embodied; (2) impacts of engineering projects on ecological elements are mainly analyzed qualitatively but not quantitatively; (3) researches on corresponding impact assessment and prediction are not undertaken in a systematic way, especially for the lack of comprehensive assessment indicator systems and shortage of full reflection on characteristics of different stages of engineering projects; (4) impact assessment procedures are often not integrated. To solve the above problems, it is necessary to realize systematism, quantification and integration for concerned researches. The specific scheme contains: designation of key ecological factor identification method; establishment of ecological environmental impact assessment indicator system; creation of comprehensive ecological environmental impact assessment method for certain engineering projects; and perfection of impact assessment procedure.
