Sanjiang plain is the biggest freshwater wetland in China, and it plays an important role in regional ecological environment construction. Based on expatiating the general situation of Sanjiang plain, the ecological problems due to the variation of Sanjiang wetland were analyzed, including the area decreasing of wetland and the degradation of its function, the decreasing of biodiversity, the losing of water and soil, the variation of climate, the pollution of soil and water. It suggested that the regional climate changing, unreasonable exploitation and the tension of population are the reasons that the Sanjiang plain was destroyed. The strategy of protection and sustainable development of wetland resources was put forward, such as establishing information system of Sanjiang wetland resources, strengthening the construction and management of wetland natural reserve, adjusting the structure of industry, developing the ecological agriculture, giving up cultivation to wetland in order to resume the structure and function of ecological system, coordinating the relationship between wetland and industry, agriculture as well as city development, and enhancing propagandizing and education.
