01圈层规划|Layers of planning
At the beginning of the intervention design in 2012, the team put forward the concept of “circle planning”, based on the original wetland resources, using green ecological technology, to build a circle protection system, and achieve the integration of ecological protection and tourism and leisure. According to the ecological situation of sanwan canal, we are divided into three circles, namely, wetland protection, wetland buffer and participatory wetland. According to the division of the whole circle, our corresponding design can meet the needs of three categories of human activities. The space not only perfectly constructs the ecological protection system but also harmoniously integrates with the sightseeing and leisure.
