| Based on a literature review of over 1 hundred cases, this paper received almost full understanding of green landscape evaluation of both home and abroad, after then the Tianjin Airport Econimic Area was choose to be the research subject. With plenty of field investigation conducted and much background information collected, we refined the evaluation factors and determinated the evaluation method. Totally seven subjects were settled down to be researched: evaluation of the landscape patterns of Tianjin Airport Econimic Area, evaluation of the ecological benefit of the green landscape, evaluation of the plants selection and application, evaluation of the soil properties, planning of green landscape system and ecological protection, green landscape maintenance and management, and comparison of similar area of Tianjin.Generally speaking, in one hand, Tianjin Airport Econimic Area had made good progress in green landscape conduction. The greening facilities was adding, the area of green land was increasing, the green landscape system leading by road greening was forming, the daily maintenance and management of green landscape was well conducted, the corresponding rules and regulations were getting perfect, the datebase was developing, and the personnel training and research were smoothly promoted. In the other hand, Tianjin Airport Economic Area faced some kinds of problems and challenges. The soil of this area was impoverish and of heavy saline-alkaline. The patches of green landscape were rare and crushing. The number of plant species was not abundant enough and the plant diversity was poor. The ecological benefit of the green landscape cannot face people's requirement. The cost of maintanence and management was high. In view of this, some suggestion was put forwards by experts.Besides, a"experts guided, work team leading, multiple participating and supervising"working mode was developed during the research. This working mode was supposed to guide the future research. |
