Abstract
Wetland as one of the natural landscapes with the richest biodiversity and most closely related to our life is widely distributed all around the world, and capable of storing flood, preventing drought, purifying environment, adjusting climate, controlling pollution, maintaining regional ecological balance. Nanchang is famous for "City in the Lake and Lake in the City", and this paper begins with wetland resources in Nanchang City, analyzes problems of local wetlands. Taking the design of the Aixi Lake Wetland Park for example, this paper proposes suggestions for the renovation and improvement by analyzing the problems of its current landscape pattern, and specific problems in the landscape design of wetland park, and summarizes the ecological model fit for the landscape design of urban wetland park in Nanchang City. The research contributes to the ecological restoration and conservation of wetland resources in Nanchang.

Wetlands account for nearly 6.4% of the global land area, as one of the most widely-distributed ground landscapes and habitats, wetlands together with sea and forest are titled as the major three ecosystems of the world1'1. The nature of wetland park is to use the existing or already-degraded wetlands in cities or outskirts of the cities, restore wetland ecosystem by rebuilding it or using totally artificial means, but the whole process follows the laws of ecology. In this way, wetland will become a crucial component of urban green system, and the park highlights ecological, natural and themed features of the wetland ecosystem, and realizes such functions as wetland research, ecological science popularization and education, ecological sightseeing, ecological conservation and so on1'1. There are successful cases of wetland park design in China, however, the overall design concepts and techniques are not mature for the primary recognition and research level. This paper tries to provide references for the ecological design of the urban wetland landscapes in China by analyzing ecological landscape design concepts of the Aixi Lake Wetland Park in Nanchang City, Jiangxi Province.
