2. Value and Significance The construction of the Hangzhou Olympic Sports Center can promote the transformation of Hangzhou's urban spatial pattern and promote urbanization.

Hangzhou Olympic Sports Center can not only host large-scale intercontinental and national sports events, but also become a large-scale urban complex integrating culture, commerce, tourism, residence, performing arts, food, leisure, vacation, shopping and other functions.

The architectural features and layout structure of the Hangzhou Olympic Sports Center: 1. The architectural features of the "Big Lotus" stadium are as follows: The white space between the "petals" is similar to the view windows of traditional Chinese architecture.

The internal space and the external landscape interact through the new "floor-to-ceiling windows"; the borrowed scenery gives the "Big Lotus" a classical and romantic atmosphere under the steel structure frame.

The petals are arranged staggeredly, and each petal is not solid, but forms a translucent "cicada wing" like a grid.

The use of perforated metal plates is a "magic touch" in stadium architecture. Different times, different seasons, different light and shadows, through this translucent canopy, show the gentleness and agility of the "Big Lotus".

The petals are made of aluminum magnesium manganese plates. The outside scenery can be clearly seen from the inside, including the Qiantang River, but the inside cannot be seen clearly from the outside. The lighting effect is good, and the wind and dust from outside cannot enter.

2. Layout structure The Hangzhou Olympic Sports Center has a layout structure of "green core as the core, extended axis, blended with water and green, and surrounded by five areas".

The green core is the core: the center of the area combines the Qijia River water surface and the open and undulating green space to form a natural core landscape; axis extension: fully consider the landscape effect and axis relationship that echoes the core area of ??Qianjiang New City on the north bank of the Qiantang River; water and green blending
